Machine presentation
The drum assembly on this model is of the suspended type, which means
that the outer drum and its motor assembly are suspended in the machine
chassis with strong coil springs in the middle and at each corner, inside the
machine. By each spring there is a damper to minimise imbalance when
the machine is operating. The union between the inner drum and the outer
drum (at the back) has two heavy-duty bearings, and is sealed with three
radial seals.

16 Machine presentation
The inner drum is driven via four V-belts by a frequency-controlled motor,
which is mounted on a motor mounting plate under the drum assembly.
The motor mounting plate is adjustable, so that belt tension can be regula-
ted. The motor has a microprocessor-controlled control unit which allows
the motor speed, acceleration and deceleration to be controlled with high
precision.
The drain valve is a diaphragm valve which is operated by compressed air.
The door is locked when the program starts.
The machine is supplied complete with a microprocessor-based control
unit.
The electrical components are in the automatic control unit on the machine
rear.
The machine exterior is made up of:
• Front panels of stainless steel.
• Back cover of hot-dip galvanised steel, painted white.
• Side panels and top cover of either stainless steel or of hot-dip galvani-
sed steel.

Maintenance
Maintenance
The careful attention paid to all aspects of the
design of this machine means that preventive
maintenance has been reduced to a minimum.
The measures listed below will, however, need
to be followed at regular intervals, and their
frequency should be adapted according to the
actual level of machine use.
Daily
• Check that the door lock is working normally.
• Check that the door does not leak. Clean the
door sealing disk of detergent residue.
• If the machine has an automatic dispenser:
clean this (including scoops) of detergent
residue.
• Check that the drain valve is not leaking and
that it opens and closes normally.
• Check the compressed air regulator (A). If
necessary empty separated water.
Every third month
• Ensure that the external switch is “OFF”.
• Remove rear and side panels.
• Check that hoses and connections are not
leaking.
• Check that the drive belts are undamaged
and properly tensioned. If necessary adjust
the drive belts.
• Clean the filters at the steam and water con-
nections.
• Refit the panels at the end of the check.

Troubleshooting
General information about troubleshooting
The troubleshooting section is used to pinpoint a fault on the machine to a
specific defective component or unit.
If the power supply is interrupted, the programme memory will keep the
select programme in its memory for approx. 3-5 minutes.
Within this time period, the machine automatically restarts after the power
interruption.
Precautions
Only authorized personnel is allowed to troubleshoot the machine.
Prior to commencing troubleshooting, pay close attention to the
precautions in section 1.
If the power is on, be very careful when working on the the machine.
DANGER
Be very careful when measuring the motor controller since all com-
ponents have a potential difference of about 300 V compared to
Ground and Neutral.
When the green LED is lit, all components are powered with dange-
rous voltage.
When the power supply to the machine is interrupted and the motor
has stopped, the motor controller will does lose power until after
10-30 seconds.
Measurements
For information about measurement points, components and voltages,
please refer to the wiring diagrams for the machine.

Troubleshooting
Errors with no error codes
This section includes troubleshooting charts for
errors for which no error code is generated.
Errors with error codes
Error indication
Programme or machine errors are indicated by
an alarm text in the display window.
Resetting an error indication
Error indications can be reset in two different
ways:
• By pressing START, the error may be tempo-
rarily reset. The machine then continuous the
programme that was already started. If the
error code remains, the error will come back
at once.
• By pressing athe error is reset and the
started programme is cancelled.
Error codes
A brief summary of all error codes and the pos-
sible cause for each error is presented below.
Troubleshooting charts for all errors are presen-
ted on the following pages.
