Safety Precautions
•The machine is only intended for washing with water.
•Do not allow minors to operate the machine.
• Installation and maintenance work should only be done by authorized
persons.
•Do not bypass the door lock of the machine.
•Any leaks, e.g. a worn-out door seal, should be repaired immediately.
•Prior to repairs or maintenance, be sure to read the corresponding

Warnings
The service manual includes the following warnings that warn of possible
injuries. Next to each warning text, a page reference refers to the page
where the warning can be found in the manual.
DANGER
Be careful when measuring the electric components in the motor
control. All components have a potential difference of approx.
300 V in relation to protective earth and neutral. When the green
LED on the motor control card is lit, the components carry
dangerous voltages. The motor control lose all voltage about 10-30
seconds after the voltage has been disconnected and the motor has
stopped.
Chapter 30, pages 2 and 5.

Description
General
The machines covered in this manual include the
following models:
Drum volume Model name
(litres)
65 W365H
75 W375H
105 W3105H
130 W3130H
180 W3180H
240 W3240H
300 W3300H
The machines feature an electronic programme
unit with fixed washing programmes that may be
changed using optional accessories. The
programme unit also has an in-built self-
diagnosis programme, which increases the
possibilities for quick troubleshooting.
The motor is frequency-controlled and is
controlled by an advanced motor control. This
allows precise and flexible control of the motor
rpm for any application.
The machines are supplied to customer
specifications with e.g. electric or steam heating
or no heating, and may be connected to various
combinations of cold, warm and hard water.
The machines are designed for installation in
hotels, laundries (such as apartment buildings
and coin laundries), factories, hospitals, various
institutions, etc.

Programme unit
The control panel has seven buttons for selection
of fixed machine programmes, two or four
optional buttons and a combined start/pause
button with rapid advance. The panel also has six
symbols and ten LEDs, which indicate the
progress of the selected programme.
Furthermore, there is a display for water
temperature, remaining programme time and
error indications.
Using the instantaneous values from the motor,
the machine weighs the loaded laundry prior to
each wash and then adapts the amount of water
to the laundry in the machine.
The programme unit controls the water valves,
drain valve and heating via the communication
card in the rear control unit. This unit can also be
connected to send control signals to external
units for detergent pumps and external water
valves.
The programme unit of the machine is described
in detail in section 23. Programme unit.

Motor and motor controller
A frequency-regulated motor using a drive belt
drives the drum. The motor is situated on a motor
shelf, under the outer drum with a tensioner
device for the drive belt.
The motor control relies on microcomputer-
control and controls acceleration, rpm and
retardation of the laundry drum with high
precision. Further, the motor control can supply
simultaneous values that can be used as
warnings for unbalanced loads and to calculate
the weight of the load.
The motor control communicates with the
programme unit through a serial interface.
The motor and motor control is described in
detail in section 30. Motor and motor control.

Door lock
The door lock is an electro-mechanical type with
double safety switches. The lock is bi-stable, i.e.,
it needs to receive an active pulse from the
control in order both to lock and unlock the door.
A separate printed circuit board, called door lock
control, can be fitted onto the programme unit.
This board controls locking and unlocking. The
card has separate checks for empty drum and
stopped drum. Together with the checks built into
the programme unit, this guarantees that the
door cannot be opened by a mistake.
The door lock on the machine is described in
detail in section 29. Door and door lock.

Heating
When using electric heating, the water for
washing is heated by three heating elements
accessible from the front of the machine.
The machine can also be fitted with steam
heating using a steam valve fitted on the rear of
the machine.
The heating system of the machine is described
in detail in section 40. Heating.
Water connections
Depending on the machine size and customer
specifications, the machine has one, two, three or
four inlet valves.
This unit also holds eight connectors for external
detergent supply.
Rear control unit
This box contains the main power switch or a
connection block for the input voltage, heating
contactor and a communication card with outputs
that control the water and drain valves of the
machine as well as the heating. There are also
connection blocks for connection to e.g., an
external detergent supply.
The rear electric box of the machines is
described in detail in section 21. Control unit.
