A Warning and Safety Instructions

1 General Information Danger!

The low voltage produced in the electronic is not fully electrically isolated from the power supply. If power supply connection is via a reversible plug, and if this is reversed, then the live (phase) voltage is not applied to terminal [1] or [L] at the terminal block. If a plug contact is then disconnected, e.g., from the NTC temperature sensor, supply voltage is applied to these plug contacts.

Note:

Before starting any service work, disconnect the machine from the power supply. Service and repair work should only be carried out by qualified persons in accordance with all appropriate local and national safety regulations.

When carrying out measurements on an electronic connected to the power supply, always use narrow measuring probes. Contacts are very closely spaced and using thicker probes may cause short circuits.

For extra safety it is advisable to install a residual current device (RCD) with a trip current of 30mA or less (in accordance with DIN VDE 0664, VDE 0100 part 739). All regulations of the appropriate utility supply companies and standards relating to safety (not limited to electrical safety) are to be complied with. After any repair or service work, it is essential that an electrical safety check is carried out in accordance with DIN VDE 0701-1, part 1.

2 Touch Current Measurement Note:

Touch current measurement should be carried out on all accessible conductive parts that are not connected to ground.

Warning!

Touch current measurement should only be carried out after the ground connection of the machine under test has been checked and found to be satisfactory!

Dangerous voltages may exist on defective machines as well as on accessible conductive parts that are not connected to ground!

Note:

Touch current measurement should be carried out on the following accessible conductive parts: None.

3 Risk of Injury Due to Sharp Edges and Protruding Parts Danger!

There may be a risk of injury due to protruding parts. Protective goggles should be worn.

There may be a risk of injury due to sharp edges. Protective gloves should be worn and the edge protection (mat. no. 05057680) should be used.

4 Uninstalling the Dishwasher Before the machine is removed from its installation niche, the appliance feet must be screwed in (for positioning, refer to the installation plan). If this is not done the feet could become damaged.

If the machine is installed on skids, adjusting the feet is not required.

5 Service Work – Casing Warning!

If it is necessary to tip the machine when working on its lower areas, it may only be tilted onto its back.

The appliance must not be tilted onto its left side as this would cause brine to run out of the salt container.

After work has been completed and the machine installed again, a short program without load should be carried out. This is to remove any salt residues that might be present and to prevent possible corrosion.

6 Installation Aids Containing Silicone Warning! Installation aids that contain silicone, e.g., silicone grease, are not suitable for use in dishwashers because of the damage they can cause.

If, e.g., hoses or seals are treated with silicone in order to facilitate installation, this could jam the circulation pump. Furthermore, ingredients in silicone grease can evaporate and damage electrical components such as heater relays.

3 Electrical and Plumbing Connections

3.1 Electrical Information The appliance is equipped with a 4-foot power cord and molded NEMA 515 plug for connection to a NEMA 5-15R receptacle (120VAC, 15-amp, 3-prong, grounded outlet).

It is recommended that the power outlet for the appliance be installed on the wall (within the cabinets), adjacent to under-counter space where the appliance is installed.

Ensure that the cabinets contain no rough edges that could damage the power cord or drain hose. If metal cabinets are used, ensure that a rubber grommet is installed around the opening.

Always exercise caution when sliding the dishwasher in or out, to prevent damaging the power cord and/or hoses.

3.2 Hard-Wired Electrical Connection Connect L1 (black) to L on the terminal block, N (white) to N on the terminal block, and GND to the ground connector.

Note: Hardwiring the dishwasher should only be done if required by electrical code.


19

G 5xxx

Do not cut the plug off the power supply cord/plug and connect it directly to the house wiring under any circumstances. This voids the warranty.

For hardwiring, the power cord must be removed from the appliance by disconnecting the cord from the terminal block located at the lower left front of the dishwasher, behind the toekick and service panel. Feed the permanent power supply cable through the strain relief and secure it directly to the terminal block.

Note: The appliance must be grounded.

3.3 Plumbing Connections 3.3.1 Intake Connection

The appliance is supplied with a 5-foot-long intake hose, equipped with a ⅜-inch female hose connection. This hose connection can be directly connected to a water supply valve or to an appropriate coupler/adapter (not included with appliance).

3.3.2 Drain Connection The appliance is equipped with a 5-foot-long drain hose with an internal diameter of ⅞“.

D Layout of Electrical Components

1 Control Panels Miele Futura dishwashers are categorized into three (3) product series, based on the type of controls.

1.1 Touchtronic This series of Miele dishwashers is operated by pushing a single button – no separate temperature or drying selections – just turn the machine on, select a program and Miele does the rest. All models include a diverse group of wash programs for multiple cleaning needs. Models are designed to maximize cleaning results and optimize water and energy conservation.

Figure D-1: Touchtronic Fascia Panel (G 5505/G 5705 Shown)


20

G 5xxx

1.2 Incognito The Incognito (fully integrated) series of dishwashers has the program controls located on the top edge of the door, which can be accessed while the door is open. Neither seen nor heard, the Miele Incognito Series OCI (Optical Cycle Indicator) lets you see the progress of the dishwasher cycle via a red light, which is steady or flashing depending on the status of the cycle.

Figure D-2: Incognito Fascia Panel (G 427x/G 4570/G 5175 Shown)

1.3 Navitronic The Navitronic touch display consists of two electronic boards located behind the control panel. The front program electronic board contains touchpad sensors, which respond to finger contact. Three touchpad sensors are present on each side of the display to control the menu items displayed next to them (indicated by a small arrow) within the display area. During operation the display will show:

Figure 020-2: Child Safety Lock

2.4 Automatic Door Lock Latch (“Drying Plus” Function) This motorized door lock latch is used to close the door automatically after it has been manually placed in the slightly open position and also to further improve drying performance with the Drying plus function by opening the door automatically at the end of a wash program.


41

G 5xxx

Note: The Drying plus function is always active unless it has been deactivated in programming mode.

The latch automatically opens the door of the machine for approximately 30 minutes; see Figure 020-4. The door latch advances from position 1 (door closed, latch completely retracted) to position 3 (drying, latch completely extended), i.e. extended approximately 4 inches (10 centimeters). See Figure 020-9. This opening of the door optimizes drying results, as moisture can escape. The fan cooldown (approximately 10 to 15 minutes) prevents any damage to kitchen countertops by the expelled moisture. The warm, moist air from the cabinet is discharged into the room as it escapes through the door via the air flow from the fan. During the drying phase of the program in operation, the room air, which has been taken in by the fan and slightly warmed by the condenser, is discharged into the room from the top part of the panel (Figure 020-3). This heats up the countertop, preventing large temperature differences between the cold countertop and the warm, moist cabinet air released by the Drying plus process. This prevents the expelled moisture from collecting on the bottom edge of the countertop; see Figure 020-4.

After the Drying plus cycle has completed, the motorized door lock latch moves from position 3 (drying, latch completely extended) back to position 2 (door open, latch positioned in the center). See Figure 020-10. In this position, the adjustable door lock latch is hidden by the countertop in front of it. The customer can now open the door and unload the appliance.

For the user, the opening of the door is an additional indication that the program has come to an end. While Drying plus is running, the door may be opened at any time.

The dispenser contains a solenoid that is activated via pulses to dispense detergent and rinse aid. The first pulse opens the detergent dispenser flap. All following pulses then dispense rinse aid.

During detergent dispensing the solenoid is activated by a brief pulse and this allows the detergent dispenser flap to open.

Rinse aid is dispensed in pulses. Each solenoid pulse dispenses approximately 0.03 fluid ounces (1 milliliter) of rinse aid into the cabinet interior. 3 solenoid pulses are therefore required to dispense the normal quantity of rinse aid of 0.1 fluid ounces (3 milliliters) per wash. Each pulse is applied for approximately 10 seconds so that there is sufficient time for the rinse aid to flow into the cabinet. The pause between individual pulses is also approximately 10 seconds.

If the rinse aid container is empty, a reed switch is activated and this lights up an LED in the control panel or display. The rinse aid container has a capacity of 3.7 fluid ounces (110 milliliters).

G 5xxx

2 Function

2.1 Cabinet Construction The inner cabinet is constructed of stainless steel (1.4301) welded onto four (4) vertical U-section sub-frames. The cabinet is sound- and heat-insulated with bitumen and/or mineral wool matting.

2.2 Drying System Depending on model, Futura dishwashers may be equipped with version 1 or version 2 of recirculation Turbothermic drying.

Figure 040-1: Recirculation Turbothermic Drying

Recirculation Turbothermic drying (UTT) operates with two separate air paths:

1. Condensing circuit. To obtain a dry load, the cabinet must be dehumidified. During this process, the remaining moist, warm air in the cabinet is cooled down gradually. This is because cold air stores less humidity than warm air. During the cooling process, drops of condensation form, which deposit on the coldest places in the circuit. For dehumidification of the cabinet, moist air is extracted above the cutlery

G 5xxx

tray (front right) and directed into a condenser. This condenser is located in the right outer wall of the appliance and cool air from the exterior flows around it, thereby cooling the moist, warm cabinet air more quickly. To enable optimal heat release in the cooling circuit, its side surfaces are made of thin stainless-steel sheeting (0.004 inches or 0.1 millimeters). The dehumidified air and the condensate are returned to the cabinet via the round opening on the side. The condensate (½ water glass, maximum) is collected in the sump and the air is recirculated. At the end of the program, the condensate is pumped out.

2. Cooling circuit with ambient air. To cool the warm cabinet air, cold or cool air is required. For this, ambient air is taken in via the front bottom toekick area of the appliance and passed along both exterior sides of the condenser. These are the spaces between the condenser and the exterior wall of the appliance, and between the condenser and the cabinet wall. Then the air is returned to the room from the top rear side of the appliance. The effective heat transmission from the warmer to cooler air stream leads to increasingly dehumidified cabinet air and thereby efficiently dries the wash load.

The total separation of ambient air and cabinet air brings the following advantages:

Good drying performance is achieved independently of the type of water connection (cold or hot water).

The clear separation of condensation and cooling means there is no air outlet in the fascia panel. The interior air remains entirely in the appliance.

The function of both versions of circulation Turbothermic drying is comparable. However, version 2 has no condenser pocket. Therefore, the dishwashing cabinet is completely closed – the openings, to which the condenser pocket is attached in version 1, are eliminated. As a result, the entire area of the right side panel is cooled by the fan. The moist, warm cabinet air settles in the coldest areas of the cooling circuit and condenses on the cool cabinet inside wall. Moisture is removed from the cabinet, and the dishes dry through the residual heat. The condensation runs down the cabinet inside wall to the sump and is pumped off at the end of the program.

2.3 Fan Two different fan types are employed for the two different versions of recirculation Turbothermic drying.

In version 1, a split-pole motor (approximately 23 watts) drives 2 impellers. One impeller transports cool air to the exterior sides of the stainless-steel sheeting, which serve as condensation surfaces. The second impeller transports the water vapor in the appliance to the condensation surfaces.

In version 2, a split-pole motor (approximately 19 watts) drives one impeller, which transports cool air to the outer surface of the right side panel.

G 5xxx

2.2 WaterProof System (WPS) The WaterProof System (WPS) consists of a number of interdependent safety features to provide protection against water leakage.

1. Protection against solenoid valve leakage: Each water intake is controlled by an inlet valve. If this valve cannot close properly due to some defect or blockage by a foreign object, a second inlet valve ensures that the water supply is shut off.

2. Protection against water intake hose leakage: If a leakage occurs, water flows along an outer hose sleeve surrounding the intake hose to the drip pan. Here a float switch then acts to switch off a microswitch which closes the inlet valves to cut off the water supply.

3. Protection against dishwasher overflow: If some defect has caused the water level in the appliance to rise so that it overflows into the drip pan, and the water quantity sensor has also failed, the float switch is activated. This switches off a microswitch which closes the inlet valves to cut off the water supply. At the same time the drain pump is activated.

4. Protection against drain pump failure or blocked drain path: In this case the water level in the appliance rises until it overflows into the drip pan where the float switch is activated. This switches off a microswitch which closes the inlet valves to cut off the water supply.

2.6 Water Softener Programming If the on-site tap water hardness is above 8 grains per gallon (140 ppm), the water should be softened.

If water softening is needed: The water softener reservoir must be filled with softener salt. The water hardness level must be programmed manually. See the

separate programming-mode guide.

If water softening is not needed: Salt is not needed and should not be added. For instructions on adding water softener salt, see Section 050-4.28.

2.7 Flow Meter B3/4, Water Intake Quantity The water intake quantity is monitored by a flow meter (B3/4) integrated in the water diverter. The water flow is measured in the hard-water area. A permanent magnet located in the flow meter axle activates an external reed switch each time the axle rotates. The pulses supplied by the reed switch are registered by the electronic and compared with a target value stored in memory for the particular program or program step in operation. For each 0.26 gallons (1 liter) of water, approximately 200 pulses should be registered. When the target value (maximum number of pulses) is reached, the water intake step is stopped. If the target value has not been reached after 4 minutes, the program is interrupted and the pump operates. Then, depending on model, either the Intake/Drain LED flashes or fault code F13 (see Section 080-3.13) is displayed.

Note: For specific information regarding permissible minimum flow pressure, see the appropriate operating/installation instructions.

2.8 Electronically Controlled Water Hardness (EGS)

The EGS valve is located in the water diverter.

To prevent or avoid possible glass corrosion, the wash water hardness level should not fall below 3 grains per gallon in program steps with heating and 5 grains per gallon in program steps without heating. With supply water hardness below 20 grains per gallon (under 16 grains per gallon in heating steps), solenoid Y5 is activated to add a proportion of hard supply water to the cabinet. The proportion added in this way depends on the water hardness level set at the electronic or that measured at the sensor softener. The EGS system is not active as standard in all wash programs, but this can be programmed as an option if required.

2.9 MPEH Circulation Pump (No Slide Shutter or Frequency Converter) In the MPEH circulation pump (approximately 85 watts), all three spray arms are supplied with water at the same time. The total water circulation rate is approximately 18 gallons per minute. Approximately 4 gallons per minute

flows through the top spray arm, approximately 9 gallons per minute through the middle spray arm and approximately 5 gallons per minute through the bottom spray arm. This pump version does not have a speed sensor.

This pump is equipped with a winding changeover, which increases the torque at the moment it is switched on (higher starting torque). In this state the main winding is connected directly, and the auxiliary winding connected indirectly via the capacitor, to the power supply. During normal operation the efficiency is increased. The main winding is switched parallel to the capacitor.

The winding changes are made via a changeover relay on the electronic module. At every switch-on, the changeover relay and the circulation pump starting relay are supplied with power at the same time. The changeover relay switches the windings with a time delay.

This circulation pump has thermal winding protection.

2.10 MPEW Circulation Pump (with Slide Shutter, No Frequency

Converter) With spray arm alternation, the spray arms are only intermittently supplied with water. This is achieved via a slide shutter which is moved back and forth as appropriate to open or close water paths to the different spray arms. For 30 seconds both the top and bottom spray arms are supplied and during the next 30 seconds the middle spray arm only. The total water circulation rate is constant and is approximately 35 L/min.

Detergent is only dispensed when the middle spray arm is being supplied with water.

The circulation pump is primed via the middle spray arm water circuit. Therefore, at the start of a program, the water path control appliance first directs water to the middle spray arm.

The MPEW version installed in these models has an integrated speed (Hall) sensor.

This pump has switched auxiliary windings which are additionally activated at the moment of pump switch-on to raise the starting torque. In this state power supply voltage is applied directly to the main winding and via the operational capacitor to the auxiliary winding. During normal operation, the efficiency factor is increased. The main winding is then switched to be in parallel with the operational capacitor.

The winding changes are made via a changeover relay on the electronic module.

At every switch-on, the changeover relay and the circulation pump starting relay are supplied with power at the same time. The changeover relay switches the windings with a time delay.

The circulation pump has thermal winding protection.

Table 050-1: MPPW Pump Pressure versus Wash Program

Load sensing: The MPPW circulation pump does not have a Hall sensor to measure speed of rotation. Instead of utilizing the Hall effect, the load is registered by monitoring the circulation pump current consumption as follows: During the water intake block, a certain fixed basic quantity of water is taken into the machine. The load is sprayed with this water and some is thus retained on items in the machine. The less water that flows back into the sump, the larger the load because more water has been needed to wet the individual items. The pump then has less water to circulate and its mechanical load is reduced. By measuring current peaks, the control-power electronic (SLT) calculates the additional quantity of water that must be taken in to carry out the program.

Note: These voltages can also be measured when the pump is not activated.

2.12 Heater Element

Water heating is carried out by a ring heater element in the circulation pump housing. The heater element and circulation pump together form one component. This ensures that on models with spray arm alternation heating can always be carried out whichever water path is currently being used. Integrating the heater element in the pump housing also ensures that it is always cooled sufficiently thus preventing the baking-on of soil particles or impurities in the water. The heater rating is 1.30 kilowatts at 120 volts.

Various safety measures protect the heater element against overheating, such as the following:

Heater pressure switch NTC temperature sensor Electronic control

The heater is activated only when the circulation pump has taken in sufficient water.

2.13 Heater Pressure Switch, B1/13 Heater pressure switch B1/13 is located directly on the circulation pump and registers the water pressure when the pump is in operation.


86

G 5xxx

Using the pressure switch contacts, heating is controlled via 2 poles. The heating is switched via a heater relay located before the pressure switch contacts in the circuit. Heater activation occurs during the wash and final rinse cycles.

If the circulation pump and heater relay are activated and the pressure switch reset contact is open, the control registers a water intake fault (see Fault Code F14, Section 080-3.14).

Figure 050-12: Heater Pressure Switch

2.14 NTC Temperature Sensor R30

Temperature sensor R30 (NTC resistor) is located in the bottom area of the sump. The electronic constantly monitors the current wash water temperature via the resistance of this sensor.

If the maximum safety temperature of 194°F at the NTC sensor is exceeded, the program is interrupted (boiling prevention) and fault code F26 is registered; see Fault Code F26, Section 080-3.20.

If the sensor or its connections are open- or short-circuited, the heating is switched off. The program then continues to the end without heating or dispensing; see Fault Code F01, Section 080-3.9 (NTC short-circuited), or Fault Code F02, Section 080-3.10 (NTC open-circuited).

If, during heating, the desired temperature is not reached in the given time, a fault is registered; see Fault Code F25, Section 080-3.19.

2.15 Turbidity Sensor (ECO Sensor III, Autosensor), B3/10 G 5xxx dishwashers are provided with one of two turbidity sensors, depending on model. The ECO sensor III measures the turbidity of the water and, based on this result, the wash blocks, temperatures and running times of Sensor Wash programs are modified. In addition to this, the Autosensor has a microprocessor to evaluate the particle measurement.

Principle of operation: Water circulation and the presence of detergent cause bubbles to be developed in the suds and measurement technology cannot differentiate between these bubbles and suspended soil particles. With the turbidity sensor, a proportion of the suds are directed into a bypass channel which is wider at one end. This causes the flow rate to reduce and hence the bubbles in the water to rise. The suspended soil particles in the water can then be more accurately registered in the following measuring process.

A photoelectric barrier switch (infrared (IR) diode opposite a phototransistor) acts as a turbidity sensor. Depending on the turbidity (transparency) of the water, a certain current flows through the phototransistor. This current is measured and processed by the electronic which then initiates the appropriate action. If the level of turbidity passes certain thresholds, then, depending on the soiling detected, subsequent cleaning cycles are modified


88

accordingly with regard to water quantity, program duration and temperature.

Note: In addition, temperature compensation of the Autosensor is carried out via an integrated NTC resistor.

Figure 050-13: Turbidity Sensor Circuit

The sensor is situated in the feed pipe to the top spray arm; see Figure 050-14, Item 1.

Figure 050-14: Turbidity Sensor Location

The flow rate is approximately 4 gallons (15 liters) per minute. In order to compensate for residues on the sensor and aging of the optical system, the turbidity sensor must be recalibrated regularly. This process is carried out automatically by the electronic and cannot be modified in any way.

Measurements are carried out at different times during the pre-wash, main wash and interim rinse stages. For this the top and bottom spray arms must be supplied with water.

2.16 Spray Arms The following speeds apply to all programs except Pots and Pans, China & Crystal and Economy:

Spray arm Speed

Top 40 - 50 rpm

Middle 22 - 30 rpm

Bottom 34 - 42 rpm Table 050-3: Spray Arm Speeds

Note: The programs Pots and Pans, China & Crystal and Economy are not suitable for checking spray arm speed. These programs are designed for special applications, such as cleaning heavily soiled loads (Pots and Pans), glassware (China & Crystal) or economical cleaning (Economy), and operate with differing water pressure. The higher or lower water pressure required for these programs is produced by the circulation pump; see Sections 050-2.9 to 050-2.11.

2.17 Spray Arm Sensing, Middle and Bottom Spray Arms

Two spray arm sensors are installed on the water intake to monitor the bottom and middle spray arms. A small magnet is installed on one end of each of the two spray arms.

The sensor for the middle spray arm is monitored when the circulation pump is in operation and the slide shutter is in the middle spray arm position. The sensor for the bottom spray arm is monitored when the circulation pump is in operation and the slide shutter is in the top and bottom spray arm position. If the slide shutter position is undefined or if a fault occurs, monitoring is not carried out.

The time period during which the spray arms are monitored is given by the electronic. If a fault is detected, it will be indicated but not saved in the fault memory. The indication will be canceled when the fault is remedied. The minimum spray arm speed is approximately 5 revolutions per minute. Therefore, the next pulse should be registered approximately 12 seconds after the start of the monitoring time.

The maximum spray arm speed is approximately 50 revolutions per minute. Therefore, the next pulse can be registered at the earliest approximately 1.2 seconds after the start of the monitoring time.

If a fault is indicated, the indication will remain active even after the door has been opened. To cancel the fault indication, the door must be closed again.

2.18 Filter Combination with Microfine Filter Circulation pump M6 pumps the wash water from the sump via the filter combination to the spray arms. The circulating wash water is filtered via 2 parallel paths. A proportion of the water flows through the central opening of the coarse filter and then passes through the conical microfine filter (Figure 050-16, Item 3). The remainder passes directly through the large surface area fine filter (Figure 050-16, Item 2), which contains a small hole for ventilation of the suction area of the circulation pump. Both partial currents are continually redistributed via constant circulation in the cabinet, so that all suds flow through the microfine filter. Soil that is retained by the microfine filter either collects there or falls onto the filter cap where it will eventually be flushed out by the drain pump.

The crown coarse filter (Figure 050-16, Item 1) is attached to the filter combination handle. If dispensed powder detergent should fall into the microfine filter, it remains on the filter cap where it can dissolve. This prevents it from collecting in the drain outlet. Foreign objects which pass the crown

2.19 Drain Pump

Drain pump M8 is driven by a synchronous motor and is located under the cabinet on the left next to the sump. It is directly activated by the electronic. In case of fault, drain pump M8 can be directly activated via overflow float switch B8/3. The drain pump pumps the suds via the non-return valve and the drain hose to the on-site drain.

Drain pump M8 extracts water from below the microfine filter. This reverses the direction of flow through the microfine filter that normally exists during the dishwashing cycle. Soil particles that have been trapped in the filter during dishwashing are then flushed out with the drain water.

Pump capacity: Max. 13'1" hose length Max. 3'3" head height

Most faults will cause the program in operation to be interrupted and the drain pump to start.

If the WaterProof System has been activated (Fault Code F70, Section 080-3.33), the drain pump continues to run even after the appliance has been shut off. In this case, the pump is switched off only when the main power cable is unplugged or by removing water from the drip pan.

The drain pump of has a rated output of 32W. The flow rate is 6 liters per minute (3 liters per minute nominal) at 1m pump head height and 4m hose length. The applied voltage is the nominal rated voltage minus 15% (Vnom -15%).

2.2 Component Test

After selecting the service mode (Section 080-4.2) and successfully accessing the component test program, individual electrical components can be activated via the program selection button or the Start/Stop button, depending on model. During this procedure, certain components can only be activated via special mini-programs.

2.2.1 Test Sequence and Background Information

Note: In models without displays, one of the LEDs will flash corresponding to the test step (e.g., one quick flash for test step 1, one slow flash and one quick flash for step 11, etc.). In models with displays, the test step is indicated by "Vxx", where x is the step number (e.g., "V01" for step 1).

1. R1, Y63, M6, ... Wash sequence with heating (mini-program): This starts with 30 seconds drainage which begins with pulsed priming (2 seconds on/2 seconds off). The water inlet valve is then activated until 1.4 gallons (5.4 liters) has been taken in. Concurrently with water inlet valve activation, the slide shutter (if applicable) is set to the middle spray


116

G 5xxx

arm position. After 0.7 gallons (2.7 liters) has been registered, the EGS (electronically controlled water softener) valve is also opened until the total desired intake quantity has been reached. The circulation pump with switched auxiliary winding is then operated. At the same time the slide shutter is activated with its setting alternating at 15-second intervals. After a further 60 seconds, the heater relay is switched on for 300 seconds and the water is heated to 122°F (50°C). The mini-program ends with 30 seconds drainage which begins with pulsed priming (2 seconds on/2 seconds off).

Note: This mini-program does not include any fault-testing function.

2. 1K1 or K1/1, heater relay: The heater relay is activated for 60 seconds.

3. M8, drain pump: The drain pump is activated for 60 seconds.

4. Y63, Y5, water inlet valve with EGS valve (mini-program): The water inlet valve is activated (on models with and without slide shutter) until 1.4 gallons (5.4 liters) has been taken in. After 0.7 gallons (2.7 liters) has been registered, the EGS valve is also opened until the total desired intake quantity has been reached.

Warning! If the flow meter is defective, the EGS valve will not be activated.

5. Y5, EGS valve: The EGS valve is activated for 60 seconds. (Vacant in models without EGS valve.)

6. M6, circulation pump auxiliary winding relay: The circulation pump with switched auxiliary winding is activated. With a controlled circulation pump, the activation is at the maximum speed for controlled operation. The circulation pump is activated for 30 seconds but the auxiliary winding relay is only activated during the first 15 seconds.

Note: During the period when the auxiliary winding relay is activated, a higher circulation pump current (approximately 0.9 amps) flows. After this period, the current drops to approximately 0.16 amps.

Warning! The circulation pump must not run for more than 30 seconds without water.

7. M24, M6, slide shutter at middle spray arm setting with circulation pump: The slide shutter is activated and set to the middle spray arm setting. The circulation pump is then operated for 30 seconds at the maximum speed for controlled operation. (MPEW and MPPW only.)

8. M24, M6, slide shutter at top/bottom spray arm setting with circulation pump: The slide shutter is activated and set to the top/bottom spray arm setting. The circulation pump is then operated for 30 seconds at the maximum speed for controlled operation. (MPEW and MPPW only.)

9. M24, slide shutter: The slide shutter is activated for 60 seconds. (MPEW and MPPW only.)

10. Y50, combination dispenser: The combination dispenser is activated with


117

pulsed operation for 60 seconds. The pulse rhythm throughout the test period is 10 seconds on/10 seconds off.

11. Y38, Y5, ... Reactivation sequence (mini-program): This starts with 30 seconds drainage which begins with pulsed priming (2 seconds on/2 seconds off). The water inlet valve with EGS valve is then activated until 8.3 fluid ounces (250 milliliters) has been reached or 60 seconds has elapsed. The reactivation valve is then activated for 150 seconds. Following this the water inlet valve and the drain pump, which begins with pulsed priming (2 seconds on/2 seconds off), are operated together for 60 seconds.

12. Y5, EGS valve. The EGS valve is activated for 60 seconds.

13. Y38, reactivation valve: The reactivation valve is activated for 60 seconds.

14. M2, fan: The fan is activated for 60 seconds.

15. M6, circulation pump: The circulation pump is activated for 30 seconds at maximum speed. If the desired speed has not been reached within 7 seconds, the circulation pump will remain stationary. (MPEW only.) Warning! The circulation pump must not run for more than 30 seconds without water.

16. 2B3-20, M6, wash sequence with middle spray arm sensor (mini-program): This starts with 30 seconds of drainage which begins with pulsed priming (2 seconds on/2 seconds off). The water inlet valve is then activated (on models with and without slide shutter) until 1.4 gallons (5.4 liters) has been taken in. At the same time the water inlet valve is activated, the slide shutter is set to the middle spray arm position. The circulation pump with switched auxiliary winding is then operated. If a spray arm fault is registered during circulation pump operation, the pump is switched off after 60 seconds; otherwise, it operates for a further 120 seconds. (Models with spray-arm sensing only.)

17. 1B3-20, M6, wash sequence with bottom spray arm sensor (mini-program): This starts with 30 seconds of drainage which begins with pulsed priming (2 seconds on/2 seconds off). The water inlet valve is then activated (on models with and without slide shutter) until 1.4 gallons (5.4 liters) has been taken in. At the same time the water inlet valve is activated, the slide shutter is set to the middle spray arm position. The circulation pump with switched auxiliary winding is then operated. If a spray arm fault is registered during circulation pump operation, the pump is switched off after 60 seconds; otherwise, it operates for a further 120 seconds. (Models with spray-arm sensing only.)

18. A2, Drying Plus (automatic door lock latch): In the home position, door contact switch S24 must be closed. After the component test begins, the latch extends until it reaches position 3 (drying position), while the door lock remains locked. Then, door contact switch S24 must be opened, and the latch moves to position 2 (door open). The door must be closed, and


118

G 5xxx

the latch is completely retracted until position 1 (door closed) is reached. Finally, the door lock is locked. (Diamond, Dimension Plus only.)

Warning! Incognito (fully integrated) models: If for service purposes the door switch has been bypassed and the see-through door installed, the locking bar must be pushed back into its home position before the door is closed. If this is not done, the hinge spring will be damaged and the entire AutoOpen drive assembly will have to be replaced.

2.3 Machine Response Following a Power Failure

Following a power failure, a program automatically continues from the point at which it was interrupted.

2.4 Turbo Function (Select Models) The Turbo function can be selected by the customer under Extras.

An increase in the wash temperature (+9°F), the final rinse temperature (+3.6°F) and the circulation pump pressure (see Section 050-2.11) can shorten the duration of certain programs without diminishing washing and drying performance.

Shorter times: The shorter times resulting from the selection of Turbo vary from standard running times by 20 to 30 percent, depending on the program.

Water consumption: Water consumption is the same in the Light Soiling and Express programs. In other programs such as Normal, Heavy Soil or Pots and Pans, water consumption is even slightly reduced, because the pre-wash step is skipped.

Energy consumption: Energy consumption increases by approximately 0.2 kilowatt-hours, as the suds in the wash cycle, for example, are heated to a higher temperature (+9°F).

The Turbo function is activated in the Sensor Wash, Express, Light Soiling, Normal, Heavy Soil and Pots and Pans programs.

The Turbo function is not activated in the special programs (such as Starch/Cheese) as shortening the running times would contradict the specific goal of the special application. It is also not activated in glassware programs (the focus here is on the protection of glassware, and the increased wash and rinse temperatures would contradict this) or the Economy program (resource-saving washing is the key aspect here and the increased energy consumption in the Turbo function would contradict this).

Note: When the Turbo function is selected, the GlassCare LED (if applicable) does not light up, even in programs under 122°F. With Turbo the emphasis is clearly on speed and not on gentle treatment.


119

G 5xxx

2.5 SensorDry Feature Recirculation Turbothermic drying is based on the taking in of cool ambient air to condense the moist, warm air in the cabinet interior. The optimal drying effect is achieved at 73°F with a full load.

The SensorDry function ensures that good drying results are achieved in the Sensor Wash program, regardless of ambient temperature or load size. These factors can normally have a positive or a negative effect on drying results.

Before the program begins (before water intake), the ambient temperature is measured by temperature sensor R30 (in the sump) and saved in the electronic. If the ambient temperature changes after the start of the program (for example, when a window is opened), this is not taken into account.

If the measured ambient temperature is below 73°F, the condenser or side panel is cooled further, resulting in the air in the cabinet being dehumidified to a greater extent. If the measured ambient temperature is above 73°F, the opposite applies: The condenser or side panel is cooled less and, as a consequence, the air in the cabinet is also dehumidified to a lesser extent.

Note: With an ambient temperature greater than or equal to 82°F, maximum values are always set for rinse aid dispensing amount and temperature, as well as fan running time.

The second influential factor is the load size. The drying efficiency classification is based on a standard load (12 standard place settings). A smaller load can have a negative impact on drying results because the larger the load, the greater the heat transfer. The load size is established during the final rinse. Here, an indirect measurement is taken depending on the rise in temperature per minute in the temperature range of 113 to 140°F. The larger the load in the machine, the longer it takes for the desired final rinse temperature to be reached. Heater performance always remains at a constant level, but every additional item in the load binds more heat energy and this extends the heating time.

The SensorDry function can affect certain parameters as follows:

Final rinse temperature: The final rinse temperature lies in the temperature range of 144 to 158°F, depending on the situation.

Rinse aid dispensing: In addition to the customer selection, 0.03 to 0.09 fluid ounces (1 to 3 milliliters) may be dispensed.

Fan operating time: The fan operating time can be between 17 and 35 minutes.

The following scenarios are possible:

1. Low ambient temperature - Large load: Optimal conditions for optimal drying results. The fan operating time can be shortened, the final rinse temperature is reduced, and no additional rinse aid is dispensed.

2. High ambient temperature - Small load: Unfavorable conditions for optimal drying results. The fan operating time is extended, the final rinse


120

G 5xxx

temperature is increased and additional rinse aid is dispensed. 3. High ambient temperature - Large load: The positive effects of a large

load on drying results are canceled out by the high ambient temperature. The fan operating time remains unchanged, the final rinse temperature is increased and the quantity of rinse aid dispensed remains unchanged.

4. Low ambient temperature - Small load: The positive effects of low room temperature on drying results are canceled out by the small load. The fan operating time remains unchanged, the final rinse temperature

is increased and the quantity of rinse aid dispensed is increased.

2.6 Drying Plus Function See Section 020-2.4.

Note: The customer can deactivate the Drying plus function in the Settings menu.

2.10 Demo Mode The appliance is equipped with up to five different demo programs (depending on model) for showrooms.

The operation and functions of the appliance are demonstrated in the Demo mode and Endless demo mode programs. These show the operating structure by means of some examples. They show, among other things, how wash programs are selected, how related background information is accessed, how extra options are programmed and how the timer function is set. In the Trade show demo program, initial commissioning in the display can be suppressed. In the Demo with sound program, the circulation pump is activated to demonstrate the wash noise. If there is water in the machine, the circulation pump runs until the program is interrupted. If there is no water in the machine, the circulation pump is switched off again immediately after activation. Also, the spray arm alternation function is demonstrated - first the middle spray arm and then the top and bottom spray arms are supplied alternately with water.

In the Drying Plus demo program, the door is automatically opened in order to demonstrate the Drying Plus function. (Models with Drying Plus only.)

To put the appliance into demo mode, access the service programming mode (Section 080-4.1) then select Showroom program.

3.9 Fault Code F01: Water/Heating NTC or Leads Short-Circuited

Symptom: After this fault is registered, the heating will not be activated and rinse aid will not be dispensed.

Cause: NTC temperature sensor R30 or its connection leads short-circuited. Remedy: 1. Check the temperature sensor and its leads for continuity. At 68°F (20°C),

the temperature sensor resistance should be approximately 14.9kΩ (± 750Ω); at 77°F (25°C), approximately 12kΩ (± 600Ω) (guide figures only).

2. Check the plug connections. 3. Replace the temperature sensor, if necessary. See Section 050-4.20.

3.10 Fault Code F02: Water/Heating NTC or Leads Open-Circuited

Symptom: After this fault is registered, the heating will not be activated and rinse aid will not be dispensed.

Cause: NTC temperature sensor R30 or its connection leads open-circuited. Remedy: 1. Check the temperature sensor and its leads for continuity. At 68°F (20°C),

the temperature sensor resistance should be approximately 14.9kΩ (± 750Ω); at 77°F (25°C), approximately 12kΩ (± 600Ω) (guide figures only).

2. Check the plug connections. 3. Replace the temperature sensor, if necessary. See Section 050-4.20.

3.11 Fault Code F11: Drainage Fault

Symptom: Water present in appliance and is not being drained off.

Background information: After each drain pump step, the circulation pump operates for 2 seconds and

heater pressure switch B1/13 checks the water level. See Figure 080-6. If it is too high (large quantity of residual water remaining in the cabinet), the drainage time is extended. If, after a further check, the water level is still too high, then the program is interrupted, the fault code is saved and the drain pump is activated.

G 5xxx

Figure 080-6: Circuit Test Path for F11

Fault code F11 is also registered if heater relay 1K1 is not activated after the fault code F51 register check; see Section 080-3.27.

Cause: Drain hose kinked. Remedy: Check the drain hose for correct positioning.

Cause: Drain blocked. Remedy: Check for proper water flow from the drain line by performing the following procedure: 1. Disconnect drain line from drain trap, garbage disposal, or drain pipe and

place in bucket or large container. 2. Ensure that adequate water is in the dishwasher cabinet. Select and start

a new wash program (first step should be a 30-second drain). Ensure that the drain hose is held in place within the bucket or container.

3. If water flows from the drain hose, the dishwasher is not the cause of the blockage. Blockage is in the piping and should be checked by a specialist.

If water does not flow from the drain hose, then check the filters. 1. Clean the on-site drain. 2. Check the sump drain. 3. Check the filters for blockage. 4. Check the heater pressure switch and replace it, if necessary. See

Section 050-4.16.

Cause: Ball in non-return valve in sump has not opened (e.g., jammed). Remedy: Check the non-return valve for blockage; clean or replace as necessary. Clean the non-return valve in the sump or replace it if necessary.


129

G 5xxx

Cause: Drain pump defective. Remedy: With the non-return valve removed, check the drain pump for proper operation by performing the following steps: 1. Check the drain pump impeller blades for proper rotation. If stuck, look for

foreign objects blocking impeller blades. If impeller blades are jammed and no foreign objects are found, proceed to the next step.

2. Remove the lower service door panel. 3. Operate the dishwasher in a drain step. 4. Check for power at the drain pump. If pump is receiving power, then

replace the drain pump. If not, check wiring from electronic to the drain pump. Replace or repair as necessary (Section 050-4.17).

Cause: Foreign objects in heater pressure switch. Remedy: Check the heater pressure switch for blockages and correct switching point. Ensure that the contacts are in the correct position after a drain step. Replace if necessary. See Section 050-4.16.

Cause: Heater relay defective.

Heater relay (coil or contacts) becomes defective during the drainage step (after fault code F51 register check).

Remedy: Replace the heater relay. See Section 050-4.10. 3.12 Fault Code F12: Water Intake Fault at Start of Step

Symptom: During the first 5 seconds of any water intake step, at least 15 pulses from flow meter B3/4 should be registered. If this given number of pulses is not detected, the display reads Water inlet fault and/or “Intake/Drain” LED flashes (depending on model). The water inlet valve will be activated at 10-second intervals for one hour. The drain pump will also be activated at intervals to prevent the possibility of the appliance overflowing. All other components remain inactive. If these attempts to achieve the minimum pulse rate fail, the buzzer is activated for 2 minutes.

Cause: On-site shutoff valve (water supply) closed. Remedy: Open the shutoff valve.

Cause: On-site water supply not in order (water pressure below 14.5 pounds per square inch).


130

electronic board to electrical connector. Replace and repair as necessary. See Section 100-4.5 or 100-4.6.

3.14 Fault Code F14: Water Intake Fault: Heater Pressure Switch

Symptom: The program is interrupted and the drain pump is operated.

Background information: With the circulation pump operating after a water intake step, the heater pressure switch is checked to ensure that sufficient water pressure exists in the wash water circuit. For this the heater relay must have been activated.

Cause: During a heating step the heater pressure switch may have registered no or insufficient water pressure at the circulation pump.

Remedy: 1. Check the dispensing of detergent and rinse aid. Excessive foam

development means that the pressure at the heater pressure switch will be reduced.

2. Check for correct water level within the machine (water level should be just under the filter arm). See Section 050-4.29.

3. Check all filters for blockages. 4. Check if the circulation pump is defective by performing the following steps:

a. Open the dishwasher door and insert the yellow bypass tool into the latching mechanism.

b. Turn on the dishwasher and select and start a wash program. c. After the 30-second drain step, pay attention to the lower spray arm.

As water enters the cabinet the circulation pump should be operating, increasing the water flow pressure. There should be a small stream of water coming out of the lower spray arm.

Warning! Keep both hands on the door handle while performing this test. If water begins to flow out of the lower spray arm, press the door handle to pop the bypass tool out of the door lock and shut off the machine. If this is not done, there is the danger of water spraying out of the dishwasher.

d. If water is flowing out of the spray arm, the circulation pump is operating and there is no blockage. Press the door handle to pop the bypass tool out of the door lock.

e. If there is no water, continue troubleshooting.

Cause: Heater pressure switch B1/13 defective or blocked by foreign objects.

Remedy: 1. Check the heater pressure switch. 2. Check the connection plug and wiring harness. 3. Replace the heater pressure switch, if necessary. See Section 050-4.16.


134

G 5xxx

Cause: Circulation pump inoperative. Circulation pressure too low (no pressure at heater pressure switch). Pump may be blocked by foreign objects. Remedy: 1. Check the circulation pump for foreign objects by performing the following

steps: a. Remove the drip pan (Section 010-4.2). b. Remove the circulation pump (Section 050-4.13). c. Remove the circulation pump housing cap (Section 050-4.14). d. Check the inner housing for blockages. Clean as necessary.

2. Check the pump’s hose connections. 3. Check the circulation pump capacitor. 4. Check the circulation pump power supply. 5. Replace the circulation pump, if necessary.

Cause: Flow meter B3/4 defective (incorrect water quantity registered). Remedy: 1. Check that the plate with the reed switch on the flow meter is seated correctly. 2. Check that the reed switch connection plug is seated correctly. 3. Replace the reed switch, if necessary (Section 050-4.7). 4. Check the control lead from the electronic to flow meter B3/4. 5. Remove the water diverter and replace if necessary. See Section 050-4.12.

Cause: Circulation pump winding overheated; winding protection has cut out. Remedy: Replace the circulation pump. See Section 050-4.13.

Cause: After a water intake step, heater pressure switch B1/13 has not opened switching steps 11–12 and 21–22. This causes the anti-stiction routine to be started. Remedy: Check the heater pressure switch for proper operation by performing the following steps: 1. Check connection plugs and wiring harness for damage, corrosion or

loose connection. 2. Access service mode (see the separate service mode guide) and select the

component test menu. 3. Select the first test, wash sequence with heating (R1, Y63, M6). 4. Access the control electronic. 5. Using a multimeter, place the probes onto the heater pressure switch sensing

leads off of connector ST5 on the electronic board. During circulation pump operation no voltage should be read at these points. If 120VAC is measured, replace the heater pressure switch (Section 050-4.16).

Cause: Circulation pump capacitor defective.


135

G 5xxx

Remedy: Check the pump capacitor and replace it if necessary. See Section 050-4.15.

3.15 Fault Code F15: Water Intake Fault - Hot Water

Symptom: The display reads Intake temperature too low and the status LED flashes (model-dependent). The program is not interrupted.

Cause: Intake temperature of the hot-water connection is too cold (below 100°F). Remedy: Have the water connection checked by a specialist.

3.16 Fault Code F18: Flow Meter Stationary State Monitor B3/4


Background information: The water inlet valve is open when it should not be (a signal to open it has not been given by the electronic). Water then flows into the appliance and unexpected pulses from the flow meter are detected. Unexpected pulses from the flow meter are also detected when the water inlet valve is not activated.

Cause: Water inlet valve defective. Remedy:

Check the water inlet valve for proper operation (may be stuck in open position). a. Access the water inlet valve. b. Start a wash program. c. Wrap one hand around the inlet valve during the water inlet step. There

should be a vibration, which indicates that the valve is energized. d. At the end of the water inlet step, the valve should be de-energized. If water

is still entering the machine, replace the water inlet valve (Section 050-4.27) e. Check for interference pulses. Electrical components within the water

diverter could be interfering with the pulses produced by the flow meter. Troubleshoot accordingly and replace the water diverter, if necessary (Section 050-4.12).

3.17 Fault Code F19: Flow Meter B3/4 Stiff and Not Turning Freely


Background information: Satisfactory test routines to monitor free rotation of the flow meter impeller could not be established.

Start rinse block water intake:


136

G 5xxx

Figure 080-7: F19 Start Rinse Block Water Intake

a Measuring time for 0.26 gallons (one liter)

1 Normal water intake time sufficient (1 minute in this example) 2 Extended water intake time required (2 minutes in this example) 3 After 0.26 gallons (one liter) intake, it is clear that neither the normal nor

the extended water intake time will be sufficient. Therefore, the test routine is started. (See below.)

Test routine:

Figure 080-8: F19 Test Routine

a Measuring time for 0.26 gallons (one liter) b Test routine successful; water intake time is extended. c Test routine unsuccessful; fault code F19 is registered.

a. During the first step, water intake solenoid Y63 is activated in order to let another 0.52 gallons (2 liters) flow into the machine. The required time is calculated on the basis of the time that the 0.26 gallons of water already in the machine required for intake.

Note: The volume of water cannot cause the machine to overflow, even if the flow meter is inaccurate.


137

G 5xxx

Circulation pump M6 is now activated for 2 minutes in order to wet the dishes in the dishwasher and to fill any spaces with water. Drain pump M8 is then activated for one minute. This creates a measurement basis for the actual test.

During the test, water inlet valve Y63 is activated until a defined number of pulses corresponding to a water volume of approximately 0.37 gallons (1.4 liters) is reached. Circulation pump M6 is then activated once more.

b. The program continues to run without interruption. The maximum water intake time is extended to 4 minutes. This time value is saved by the electronic for future water intake. For future water intakes, if the time needed for 0.26 gallons to flow into the machine differs by 15 percent, a new test routine flow will be started.

c. If heater pressure switch B1/13 is activated, the program is interrupted immediately, the drain pump is operated, and fault F19 is registered.

Cause: Flow meter defective. Remedy: Replace the water diverter. See Section 050-4.12. Fault F19 will be displayed if the check to test the sluggish movement of the flow meter (impeller counter) during the water intake is not successful.

3.18 Fault Code F24: Heater Relay Contact


Background information:

Figure 080-9: Circuit Test Path for F24

18 seconds after starting the drain sequence, the electronic will perform an operational test on the heater relay. The circulation pump is not operating and no power is applied to the heater relay coil. If 120VAC is registered at ST5 on the electronic board, then an F24 is logged in memory (see Figure 080-9). When the circulation pump is not operating, the heater relay contacts are checked. If supply voltage is then applied to the electronic’s inputs, the fault is registered.


138

G 5xxx

Cause: Heater relay contacts have fused together. Remedy: Replace the heater relay. See Section 050-4.10.

Cause: Moisture in heater relay. Remedy: Replace the heater relay. See Section 050-4.10.

Cause: Fault in the plug on the output side of the heater relay.

Contamination or corrosion on the plug of the heater wiring harness can cause a bridge between contacts, which can reduce the transfer resistance below a value of 10 megaohms (10MΩ).

Remedy: 1. Disconnect the machine from the power supply. 2. Disconnect plug ST5 from the electronic. 3. Measure the resistance between the lines of the electronic for heater

pressure switch B1/13 (pins 12 and 22 on plug ST5). 4. If the measured resistance value is smaller than 10 megaohms (10MΩ),

then the heater partial wiring harness must be replaced. 3.19 Fault Code F25: Target Temperature Fault

Background information: During the heating stage, the desired temperature has not been reached within the given time (minimum 75 minutes). In subsequent wash blocks, after this fault has been registered, the heater is not activated and no rinse aid is dispensed.

Cause: Heater defective. Remedy: Replace the heater. See Section 050-4.14.

Cause: Heater relay defective. Remedy: 1. Check the heater relay solenoid. 2. Check the heater relay solenoid voltage (12VDC) from the electronic. 3. Replace the electronic, if necessary. See Section 100-4.5 or 100-4.6.

Cause: Excess quantity of detergent or rinse aid dispensed. Excess foam has developed. Excess foam can cause a drop in water flow pressure, directly affecting the heater pressure switch. Remedy: Check the dispensed quantities of detergent and rinse aid. Clean out excess foam and follow the information given in the operating instructions.


139

3.20 Fault Code F26: Boiling Protection


Cause: Temperature at NTC temperature sensor has exceeded 194°F (90°C). Remedy: Check the heater relay and replace it, if necessary. See Section 050-4.10.

Cause: NTC temperature sensor providing inaccurate information. Remedy: Replace the NTC temperature sensor. See Section 050-4.20.

Cause: Heater relay closed. Remedy: Replace the heater relay. See Section 050-4.10.

Cause: Faulty position monitoring of the automatic door lock latch. For a switched-off appliance, the door-closing function is in operation. Under adverse conditions, the locking system can stop in a faulty position. The control electronic recognizes this as a “zero position” and interprets it incorrectly. After the first (or a later) water intake, the fault loop occurs. The machine drains for 4 minutes and, after the water intake, synchronizes the heating relay. Spray arm heating occurs up to activation of the boiling protection. Remedy: 1. Replace the heater relay. See Section 050-4.10. 2. Install a new electronic (SLT). See Section 100-4.5 or 100-4.6.

3.21 Fault Code F32: Door Lock Does Not Close

300 Technical Service Bulletins

1 Miele Policy on Dishwasher Detergent Requirements In 2005, we revised our company stance on the use of detergents in our dishwashers. Up until then we suggested powder detergents. However, with the generation of dishwashers from 2005 and continuing today, we suggest that powders, tablets, gels, and gelpacs can be used effectively in all of our dishwashers. (In fact, in support of this effort, Miele is now selling our own brand of tablets that can be found at our online store.)

Effective immediately, please begin offering the updated information for all detergent inquiries. We should no longer be advising our clients, our dealers, our service companies, or our staff that our dishwashers are "powder only."

2 Dishwasher Detergents and Phosphates Dishwasher detergents no longer contain phosphates In March, 2006, Washington State became the first state in the nation to ban phosphates from dishwasher detergents. By 2010, 15 other states adopted this policy and enacted similar bans. Faced with this growing dilemma, the major dishwasher detergent manufacturers agreed to stop producing phosphate-laden detergents by July, 2010. The quantity of the active ingredient, STPP, sodium tripolyphosphate, was reduced from nearly 35% by weight down to 0.5% by weight.

Why use phosphates? As a detergent additive, STPP is really the key ingredient. Phosphates help remove food and grease, keep insoluble dirt in suspension, maintain proper pH, reduce the risk of corrosion, and keep food and other particles from depositing on surfaces inside the dishwasher. Along with doing the lion’s share of the work, STPP is also a cost-effective additive in detergents.

Why ban phosphates? Phosphorus is one of many elements essential to life. When phosphorus gets into fresh water, it acts like a fertilizer for algae. When the bumper crop of algae later dies, its decomposition consumes oxygen in the water. Reduced levels of dissolved oxygen in water are harmful to fish. Excess levels of phosphorus can lead to widespread fish kills. In reality, the majority of phosphorus pollution can be attributed to heavy industry, mining operations, fertilizer and animal waste runoff from agriculture, and to a much lesser extent, effluent from sewage treatment plants containing trace amounts from – you guessed it – dishwasher detergents.


158

G 5xxx

Dishwashing problems without phosphates After the removal of phosphates from all major brands of dishwasher detergents in July 2010, it took about 6 months for existing store stocks to sell out. It’s no wonder that starting in 2011, consumer complaints grew at an alarming rate. Some of these complaints are:

Dishes no longer shine Gritty film left on glasses and plates Silverware turning black Food particles remaining on silverware and dishes White film & deposits on dishwasher surfaces Destruction of non-stick surfaces

What to do? These problems are being experienced by dishwasher owners all over the country. All brands and all models are affected. Our MieleCare brand detergents, also phosphate free, have been the cause of relatively few complaints, so they can be recommended as a possible solution. Other detergent manufacturers are looking for new, environmentally friendly additives, but until they find one, there is no easy answer. See the following links to learn more: http://www.appliance.net/2010/states-ban-phosphate-laden-dishwasher-soap-1988 http://pressroom.consumerreports.org/pressroom/2010/08/low-phosphate-dishwasher-detergents-that-work.html

3 G 5000 Inlet Hoses; Update There is a new inlet hose available for the G 5000 dishwashers. The inlet hose/inlet valve assembly has been updated with a new part number. 07934070 will no longer be available – 07934071 (or higher) should be used exclusively.

The difference: The new hoses have a stainless-steel braid on the exterior. On the old hoses, this braid was plastic. The new hose is stronger and much less likely to suffer damage from sharp objects, kinking, etc.

Replacing the hose: Any time you find that the outer plastic braid is damaged in any way, the hose assembly should be replaced. A damaged braid can lead to hose failure. In all cases, the hose and valve should be replaced as a complete assembly. The hose and valve are assembled at the factory, and they are matched and torqued to prevent the chance of any leaks.

After replacement: All damaged hoses or failed valves must be returned to Princeton. Mark the parts with the AMS order number as well as the model and serial number. Send the parts to the attention of Engineering Services.

4 G 5775 Fascia Panel Mounting This is a possible series fault: 11235

In some cases, either after service or during operation, it is no longer possible to secure the fascia panel to the door of the dishwasher. This is because the plastic mounting channels on the power/control unit frame have broken or chipped away (see first photo). Currently there is a repair kit available to re-attach the fascia and electronic. Use part number 09852170.

When encountering this issue, be sure to mark the bulletin number when closing the AMS order.

The repair kit is a metal bracket that links the electronic and fascia panel. Detailed instructions are packed with the kit. There is normally no need to replace the electronic or fascia.
