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 two (UK built) or four (Polish built models) 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.
3. 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.
4. 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.

Connecting the Water Inlet Hose.
Before making the water
connection to the 3/4"
thread, allow the water
freely from the supply tap
until it is perfectly clear.
Check that seal is in place
inside the hose end cap.
Connect the other end of
the water inlet hose to the
washing machine,
screwing it onto the cold
waterinlet,situatedonthe
top right-hand rear of the
appliance - see
illustration.
!Screw the inlet end with the blue cap onto the cold water supply tap.
Turn the tap on and check for leaks: tighten if necessary.

Indesit Company
Service Manual UK English
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.
The first wash cycle
Once the appliance has been installed and before you use it for the first time, run a wash cycle
without detergent and no laundry, setting the 90°C programme without a pre-wash cycle.

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.

PROGRAMMES - ALL MODELS
Eco Wash cycles
The Eco Cycles assure energy saving by eliminating the need of heating water and it’s an advantage both to your ener-
gy bill and the environment!
These innovative Eco programmes (Cotton, Synthetics and Fast Wash) are available for various fabrics and diffe-
rent quantity of garment; they have been designed to guarantee a high cleaning action even at low temperature
and can be used for lightly to medium soiled loads.
Eco Cycles give the best results thanks to an intensified wash action, water optimization and are carried out in
the same average time of a standard cycle.
For the best washing results with Eco programmes we recommend the usage of a liquid detergent.
The information contained in the table is intended as a guide only.
For all Test Institutes:
1) Test wash cycle in compliance with regulation EN 60456: set wash cycle 1 with a temperature of 60°C.
2) Long wash cycle for cottons: set wash cycle 2 with a temperature of 40°C.
3) Short wash cycle for cottons: set wash cycle 3 with a temperature of 40°C.

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.
