Safety Precautions
All external equipment which is connected to the machine must be CE/EMC-approved
and connected using an approved shielded cable.
Safety Precautions
The machine is only intended for water-wash use.
Do not allow minors to use the machine.
Do not hose down the machine with water.
The machine's door lock must under no circumstances be bypassed.
If the machine develops a fault, this must be reported to the person in charge as soon
as possible. This is important both for your safety and that of others.
The machine is not intended to be used by people (including minors) with reduced
physical or mental capacity or lack of experience and knowledge. Such people must
be instructed in the use of the machine by a person who has responsibility for their
safety. Minors must be supervised to ensure that they do not play with the machine.
Warnings
The service manual contains the following warnings concerning serious personal injury.
Next to each warning is a reference to the page and section where the warning text is located
in the manual.
DANGER
Take care when measuring the motor control system since all components have a
potential difference of approximately 300V in relation to protective earth and neutral.
The components will contain dangerous voltages when the green LED on the motor
control board is on.
The motor control system will remain live for 10-30 seconds after cutting the power to
the machine and the motor has stopped running.

Description
General
The machines covered in this service manual
include the following models:
Drum volume Model name

65 W465H
75 W475H/M/N
85 W485M/N

The machines feature an electronic programme
unit with fixed washing programmes that may be
changed using optional accessories. The pro-
gramme unit also has an in-built self-diagnosis
programme, which increases the possibilities for
quick troubleshooting.
The motor is frequency-controlled and is control-
led by an advanced motor control. This allows
precise and flexible control of the motor rpm for
any application.
The machines are supplied to customer specifi-
cations with e.g. electric or steam heating or no
heating, and may be connected to various com-
binations of cold, warm and hard water.

Function
General
This section presents a general overview of the functions of the machine.
Most functions are then presented in detailed in separate chapters later on
in this service manual.
The machine is freely suspended, which means the outer drum and motor
are mounted on a supporting ”cradle” that rests on four shock absorbers
for dampening the imbalance in the machine.
The washer drum (inner drum) is belt driven by a motor. This motor is loca-
ted at the bottom of the machine and is mounted on the cradle with a belt
tensioner. The inner drum is mounted to the outer drum at the rear plate
with two bearings sealed against leakage with sealing rings.
The drain valve is a water-controlled diaphragm valve alternatively, an
electrical drain valve or drain pump.
The door is of sturdy type that is interlocked with a lock module when in
operation.
The control panel contains a program knob for selecting the fixed wash
programs and a display.
The program unit is mounted inside the control panel. Contactor, water
valves, etc., are located at the back of the machine.

Program unit
The control panel contains a program knob and
a display. The panel can also be equipped with
two preset buttons.
The control panel and display are used by:
• theusertoselectthemachine’sxedwash
programs, to select up to two options for
each wash program and for information on
the wash process and any fault indicators.
• servicepersonnelfornavigationandcontrol
oftheprogramunit’sserviceprogram.
• programmingpersonnelforsettingandpro-
gramadjustmentintheprogramunit’ssoft-
ware.
If present, the preset buttons are used for direct
start of two preset wash programs.
Using information on torque values from the
motor, the weight of each wash is measured
before each wash program in order to adapt the
amount of water used for washing.
The program unit controls the water valves, drain
valve and heating via an I/O board in the rear
electrical module. Control signals to external
units, such as detergent pumps or external water
valves can also be engaged here.

Motor and motor control
The washer drum (inner drum) is belt driven by a
frequency controlled motor. The motor is located
on a motor shelf under the outer drum and has
been arranged with a belt tensioner.
Motor control is microprocessor controlled and
can control the acceleration of the drum, its rpm
and its retardation very precisely.
Motor control communicates with the program
unit through a serial interface.

Door lock
The door lock is electromechanical with twin sa-
fety breakers. The lock is bi-stable, i.e. the lock
must be given an active signal from the program
unit to lock as well as unlock the door.
A separate circuit integrated in the program unit
checks and controls the locking and unlocking
of the door through a lock module. The circuit
has separate controls that the drum is empty
and that it is stationary. Through sensors in the
lockmodule,thecircuitchecksthedoor’sclo-
sed and locked position. Together with other
controls the program unit conducts, this will
guarantee the door cannot be opened by mis-
take.

Heating
Electric heating heats the washing water with
three elements accessible from the front of the
machine.
Themachine’sheatingsystemisdescribedmore
thoroughly in the section Heating.
Water connections
The machine can have one, two, three or four wa-
ter inlet valves depending on the machine size and
customer requirements.
In this unit there are also eight connections for an
external detergent feeder.
Rear electric module
Contains the main switch or terminal block for
incoming power, heating contactor, I/O board with
outputsforcontrollingthemachine’swaterand
drain valves and heating. Some machines have an
additional I/O board with terminal blocks for con-
necting e.g. external detergent feeder.

Detergent compartment
The detergent compartment has four compart-
ments for prewash, main wash, rinse and
bleaching agent/liquid detergent.

compartment.
Drain valve
The valve is a diaphragm valve that is opened
and closed through water pressure. The control
valve is mounted by the water valves.

Frame and suspension
The machines are freely suspended, i.e. the
drum package can move and is suspended in
relation to the frame. In this way, a minimum of
vibration passes to the bottom plate, which in
turn simplifies installation as a concrete founda-
tion is not required.
The machine has four shock absorbers between
the bottom plate and the drum package.
