INSTALLATION
Unpacking
1. Unpack the washing machine and check whether the it has been damaged during transport.If this is the case, do not install it and contact the retailer.
2. Remove the four protective screws (transit bolts) and the rubber washer with the respective spacer, situated on the rear of the appliance (see Figures below).
3. Fit the blanking plugs provided into the holes vacated by the bolts.
4. Use the plug provided to seal the holes where the mains plug was housed (if supplied), situated on the lower right hand side on the rear of the appliance.
5. Keep all the removed parts as they will be required again if the washing machine needs to be moved to another location.
Levelling
1. Install the washing machine on a flat sturdy floor, without resting it up against walls, cabinets etc.2. Compensate for any unevenness by tightening or loosening the adjustable front feet. The angle of
inclination, measured according to the worktop must not exceed 2°.Levelling the appliance correctly will provide it with stability and avoid vibrations, noise and shifting during operation. If it is placed on a fitted or loose carpet, adjust the feet in such a way as to allow enough room for ventilation underneath the appliance.
This raised part is attached to the polystyrene base and should have been removed when unpacking.
Remove 4 transit bolts.

DRAINAGE CONNECTIONS
A. Connect the drain hose, without kinking it, to a draining duct or a wall drain fixed at a height between 65 and 100 cm from the floor. See Fig.1.
B. Alternatively, place it over the edge of a basin, sink or tub, fastening the hose supplied to the tap. See Fig.1.
The free end of the hose should not be under water.Note: We advise against the use of hose extensions. In case of absolute need, the extension must have the same diameter as the original hose and must not exceed 150 cm in length.
Undersink Connections:
The drain hose may be connected to an undersink trap. Before connecting the drain hose from the machine ensure that any blanks or removable ends have been taken off the spigot. See Fig.2.
Note: The hose must also be raised up in a similar way to a standpipe installation to prevent backflow of waste water from the sink into the machine. See Fig.1.
Electrical Connections
Before plugging the appliance into the mains socket, make sure that:
- the socket is earthed and in compliance with the applicable law.
- the supply voltage is included within the values indicated in the Specifications page.
- the socket is compatible with the washing machines plug. If this is not the case, replace the socket or the plug.
Location
! The washing machine should not be installed in an outdoor environment, not even when the area is sheltered, because it may be very dangerous to leave it exposed to rain and thunderstorms.
! When the washing machine is installed, the mains socket must be within easy reach.
! Do not use extensions or multiple sockets.
! The power supply cable must never be bent or dangerously compressed.
! The power supply cable must only be replaced by an authorised serviceman.
WARNING!
The company denies all liability if and when these warnings are not respected.

CONTROLS INFORMATION
A single control board located at the back of the machine contains all the circuitry to control the machine and interfaces with the programme selector, option buttons and LEDs located on the console panel. The control board has an access port to the rear of the machine.Programmes are selected by turning the rotary switch to one of the 16 positions. Special options can be selected by pressing the appropriate buttons and the programme process followed by LEDs.The machine is switched on using the On/Off button and selected programmes started by pressing the Start/Cancel button.
Automatic Features
Auto Half Load
Auto half load adjusts the amount of water in the wash load depending on the absorbency of garments in the wash load.
Fabric Conditioner Dispensing
Dispensing of fabric conditioner is achieved by energising both the Pre-Wash and Main Wash cold valves.
Out of Balance Protection
The machine has an inbuilt feature to prevent spinning with an unbalanced load. A calculation via the motor tacho and control board detects the current drawn by the motor during distribution.Before each spin, the controls senses the load within the drum and if the load is calculated to be out of balance the machine will not automatically spin to the full speed.
There are two levels of out of balance, level 1 @ 480 grammes and level 2 @ 1030 grammes.
If the out of balance is below level 1 the machine will spin at full speed, if between level 1 and level 2 the machine will spin at the reduced speed of 600 rpm and above level 2 spin at reduced speed of 400 rpm. There are 15 attempts at level 1 with 57 attempts in total, this being the same for both cotton and synthetic spins.
The wool spin has one level of out of balance @ 1.8 kg. The controls will make three attempts to achieve a balance, if after three attempts a balance is not achieved; the spin is reduced to a speed of 90 rpm.

FAULT FINDING
IMPORTANT NOTE: Disconnect the machine from Electricity Supply before any testing.
General Information
If the machine has an Earth Fault it can display erroneous fault codes. Repair any Earth Faults on the machine before using the code guide on the previous page.
Some faults will not show up as error codes:-
The module will not show up a fault if the water to the machine is turned off or if the solenoid valves are open circuit.Certain motor faults, will not show as a fault, the door will lock but the machine will not start a programme. (motor plug disconnected, faulty brushes etc.)Open circuit field windings will signal fault F01.If the motor Thermoprotector (toc) - if fitted -operates in the middle of a cycle, the machine will stop with no fault code indicated, when the thermoprotector (toc) resets the cycle will then restart.If the element goes open circuit in the middle of a programme and the pressure switch is in the full position, the machine may not signal a fault but will wash for a long extended period.
Note: This chart refers to both "commutator" (brush motor) and "three phase" (non-brush motor) models. Refer to text for appropriate information.
FAULT CAUSE SERVICE ACTIONS
