Repairs may be carried out by a qualified electrician only! The user may be put at risk and injured by improper repairs! To prevent electric shocks, always comply with the following instructions: ► If the appliance is faulty, the housing and frame may be live! ► Electric shock may occur if live components are touched
inside the appliance! ► Before commencing repairs, disconnect the appliance from
the power supply! ► If tests have to be performed while the appliance is live,
always use a residual-current-operated circuit-breaker! ► The protective conductor resistance must never exceed the
values specified in the standard! The protective conductor is crucial for personal safety and appliance function.
► When repairs are complete, perform a test in accordance with VDE 0701 or the corresponding national regulations!
► When repairs are complete, perform a function and leak test.
Comply with the following instructions:
Conduct the safety test in accordance with VDE 0701 via the connector as follows: ► The differential current must be measured on the appliance! See circuit diagrams test programme The following pictograms are used in the repair instructions:
Devices General State of the art electronics achieve economic efficiency, environmental protection, user comfort, high functionality and operating safety in electrical domestic appliances. This high quality technology requires professional handling and competent specialist knowledge. All electronic modules are fitted with components which are at risk from electrostatic voltage.
1.1.1 Components which are at risk
The following components are at risk from electrostatic voltage:
► µ processors and ICs ► Transistors, thyristors and triacs ► Diodes
1.1.2 Causes and effects
You are carrying an electrostatic voltage:
► of up to 35,000 volts if you walk across a non-conductive carpet,
► of up to 12,000 volts if you walk across a non-conductive PVC floor,
► of up to 1,800 volts if you are sitting on an upholstered chair.
The electrostatic voltage on your body is transferred to the electronic components and ESDs you touch which may be damaged as a result.
Shot down! ► A ‘dead’ component ► A ‘dead’ assembly ► A ‘dead’ appliance
Wounded! ► Damaged ► Debilitated ► Early failure

1.1.3 ESD instructions
All electronic modules and electronic assemblies feature electrostatic sensitive devices. The following measures must be taken in order to protect these electrostatic sensitive devices: Ensure that the assemblies and modules are appropriately identified. Before you touch and measure the ESDs, put on an electrostatic protection system (wrist band with earthing module). Avoid touching ESDs with chargeable plastics (film, etc.). When taking hold of assemblies, modules and printed circuit boards, try not to touch the printed conductors or connections. Keep ESDs away from monitors and television sets. Only use conductive materials or the original packaging for transportation.
1.1.4 Electrostatic protection system
The electrostatic voltage of the body is discharged via the wrist band and the earthing module. For reasons of safety this does not occur directly, but via a combina-tion of resistors. The earthing or protective conductor connection must not be damaged!

2 INSTALLATION
2.1 Installation / Connection
► Place the dryer on a level and firm surface. ► Level the dryer with the 2 height-adjustable feet.
(Use a spirit level) do not remove the height-adjustable feet.
► The dryer can be installed in combination with a washing
machine (front loader)To ensure a secure connection, use the original connection sets (see operating instructions).
► The installation location must be supplied with adequate fresh air (open window or door).
► Do not block the cooling-air grille on the front of the dryer, otherwise adequate cooling air cannot be drawn in.
► Do not install the dryer in a room where there is a risk of frost.Freezing water may damage the appliance.

3.1.1 Programme selector (1)
Single-button operation, 9 drying programmes, 4 of which are timed programmes. Automatic programmes Cotton/linen For cotton and linen washing which is to be mangled, ironed or dried cupboard-dry. Easy-care programmes For easy-care synthetic and blended fabrics and cotton washing which is to be ironed or dried cupboard-dry. Timed programme Timed programmes 20–60 min (Automatic-programm) warm for delicate textiles made of acrylic fibres or for redrying and airing up to 6 kg of washing. 10-120min at Time-programm
Low heat (3) For temperature-sensitive textiles (e.g. acrylic fibres) which are dried on a low heat. The temperature is reduced
“Clean filter” LED (2) If there is a lot of fluff in the fluff filter and/or heat exchanger, “Clean filter” is displayed, a signal sounds and the drying process is stopped. Restart is required after cleaning.
“Empty tank” LED (2) Lights up if the inner reservoir is filled as well as the water tank. Restart is required after draining.

4 COMPONENTS
4.1 Fluff filter
The fluff filter is plugged into the end shield in the area of the door. Unlike the T20 or T22, the filter must be locked in the end shield and not just dropped in. If the filter is not plugged in, a fault may develop in the air circuit and cause the appliance to fill with fluff.

4.2 Heater
The heating register consists of a heating resistor (2), safety thermal fuse (2) and an NTC (1). The heating register features an electrical connection up to the plug-in coupling.

6.4 Fluff filter droplet test generally
A blocked fluff filter obstructs the process air circuit and may cause the “Clean filter” LED to respond. Whether the fluff filter is blocked can be determined by the following measures. ► Take filter out of the end shield. ► Drip water onto the filter. ► If the water droplets remain on the filter, the filter is wetted
with washing agent or fabric softener (Fig. 1). ► Remove coating under warm water.

58300000141105.doc – 30.06.09 Seite 28 von 32
7.2 Unsatisfactory drying result
Customer complaint Cause Remedial action
Appliance starts only briefly. Inserted washing is too dry (<5%). Short-circuit or shunt in conductivity system. Drum and end shield electrode soiled, e.g. by fabric softener or scented cloths.
Advise the customer. Start test programme to measure conductivity. See circuit diagrams. Clean drum and end shield electrode with vinegar water.
(Programme is ready after 2–5 min.)
Ambient temperature below 5°C. Increase room temperature. Washing not uniformly dry. Wrong drying programme selected.
Blended fabric (different fabric types). The residual moisture cannot be measured correctly due to wrong types of textiles used in wrong programme (e.g. cotton textile dried in easy care programmes). Filter soiled, e.g. by fabric softener or scented cloths. (Drop test)
Advise customer. Select programme with higher degree of drying. When programme ends, additional drying temporarily.
Check kind of textiles and programme selection used by customer. Advise customer to use only cotton programmes to cotton textiles and easy care programmes to synthetics. Easy care does not mean delicate drying! This function is available with Delicate button. Clean filter under warm water
58300000141105.doc – 30.06.09 Seite 29 von 32
Customer complaint Cause Remedial action
Residual moisture in the washing too high. Was the washing spun adequately? Does the fault occur only occasionally?
7.3 Time jumps
Drum and end shield electrode soiled, e.g. by fabric softener or scented cloths. Drum overloaded. Fluff filter/air cooler blocked? (Conduct drip test). Wrong programme selected.
Advise customer. Clean drum with vinegar water. Advise customer. (Information in the operating instructions). Do not exceed drum load. See operating instructions. Clean filter/air cooler (see operating instructions). Advise customer.
Fault details Cause Remedial action
Time jumps at the end of the automatic-program (Not time program)
Load too high, max. +100% Very high ambient temperature > 30 °C Initial moisture too high Different types of washing. Residual humidity of the textiles differs.
