dispenser C after taking in water for the
last rinse.
- Remove all soap made solid during machine
lay up.
- Perform a 90°C cycle to remove all
manufacturing residues.
- If need be, mount appropriate bumpers to
prevent trolleys from hitting and damaging
the door.
- Never open soap compartments when the
machine is taking in water or is heating.

7.9 ORDINARY MAINTENANCE

(to be carried out by the user)
BEFORE ANY MAINTENANCE OR
CLEANING OPERATIONS, CHECK
THAT THE WALL CUTOFF SWITCH
IS OFF AND THE WARM WATER,
COLD WATER AND STEAM TAPS
ARE CLOSED (THE LATTER APPLIES
TO STEAM-HEATED MACHINES
ONLY). THE DRUM MUST BE STILL
AND DRAINED AND
TEMPERATURE INSIDE MUST NOT
°
EXCEED 40 C.
The machine requires no special
maintenance, thanks to its ergonomic design
and to the use of very reliable, first-quality
parts.
Periodically clean the external panels with a
damp cloth. Never use inflammable or
abrasive products and rub in the direction of
the satin-finish.
Always keep forced-cooling slots and
openings free from dust (the fan sucks fresh
air from the room), which are on the rear of
the machine, where the speed changer is
housed.
NEVER WASH THE APPLIANCE
USING WATER JETS.
BEFORE TURNING THE MACHINE
ON BY THE CUTOFF SWITCH ON
THE WALL, PUT ALL THE PANELS
REMOVED BACK IN PLACE.
INSTRUCTIONS FOR
MAINTENANCE AND
REPAIR PERSONNEL
8. SCHEDULED MAINTENANCE
AND ORDERING SPARE PARTS
8.1 REMOVE THE LID
To access the electrical parts of the machine,
remove the screws fastening the cover to the
back, lift the rear part of the cover and push
it to the front by approximately 5cm.
BEFORE TURNING THE MACHINE
ON AGAIN BY THE WALL CUTOFF
SWITCH, PUT ALL THE PANELS
REMOVED BACK IN PLACE.
8.2 TROUBLESHOOTING
If the machine does not work, check the
following:
- the main cutoff switch on the wall is on and
the machine is getting current;
- the door is closed;
- the green start push-button has been pressed.
- the warm water, cold water and steam taps
are open (the steam tap only for steam-
heated machines).
If the fault is not due to any of the above
causes, call the authorised after-sales service
or your dealer (see last page of this booklet).

8.3 SAFETY DEVICES

- Door closed safety microswitch: cuts off
power to the whole auxiliary circuit and
consequently stops the machine.
- Electronic thermal switch (overload cutout)
within the motor: disconnects power supply
in the event of coil overheating.
- Air-break system in the soap dispenser:
prevents wastewater from polluting the
drinkable water system in the event of a
depression.
- Normally open drain valve: enables safe
door manual opening by means of the manual
THE
puller.
- Tilt switch: avoids mechanical damage in
the event of irregular loads.
- Fuse-fitted heating elements. the electric
circuit is disconnected in case of malfunction.
8.4 PERIODIC MAINTENANCE (to be
carried out by the technical personnel)
All maintenance operations must be carried
out by the authorised after-sales service or
by qualified personnel.
BEFORE ANY MAINTENANCE OR
CLEANING OPERATION, CHECK
THAT THE WALL CUTOFF SWITCH
IS OFF AND THE WARM WATER,
COLD WATER AND STEAM TAPS
ARE CLOSED (THE LATTER APPLIES
TO STEAM-HEATED MACHINES
ONLY).
Be very careful during maintenance. NEVER
skip or ignore safety devices. Use only
original spare parts. If doubts should arise,
contact your sales person immediately,
explaining what the fault is and indicating
some information on the machine: model
and serial number (details reported on the
rating plate appearing on the rear of the
machine or inside the door, where
applicable).
MONTHLY INSPECTION
SERVICING
Clean the strains located on the outer part of
the electrically driven valves.
Make certain that the steam valve strain is
clean (this applies to steam-heated machines
only).
Clean the soap dispenser from any soap
remains.
Clean the door gasket and the tub inlet with
a cloth.
Always keep forced-cooling slots and
openings free from dust, which are on the
rear of the machine, where the speed changer
is housed.
YEARLY INSPECTION AND
SERVICING
Make certain that the floor fastening nuts are
securely closed (if applicable).
Check the wear of the belts and replace them
if necessary. If more than one of them is
worn out, replace the entire set of belts.
Make sure that the safety devices are working
properly (e.g. door and tilt microswitch).
Check that the floor fastening screws are
tight.
Make certain that the power connecting
screws are tight on the contactors and the
terminal board.
Disassemble the drain valve and clean it
inside from lint.
Check that heaters are in perfect condition
and clean them from scale.
BEFORE TURNING THE MACHINE
ON BY THE CUTOFF SWITCH ON
THE WALL, PUT ALL THE PANELS
REMOVED BACK IN PLACE.
AUTOMATIC MAINTENANCE
REQUEST
The machine keeps count of the number of
cycles it executes. After 1000 programs the
machine will flash the writing "10 00 C" for
10 seconds as the START button is pressed,
to remind the user that scheduled
maintenance is needed. Then it will carry out
the selected cycle normally.
To call off this reading and start the 1000
cycle count from scratch, press the push-
button "-" for at least 5 secs with the door
closed. Then the total number of cycles
performed is viewed and, if the push button
"-" is pressed again within 10 seconds, the
count is set to zero and ready to start back
again.
8.5 IDENTIFYING AND ORDERING
SPARE PARTS
AND
To identify the codes of spare parts refer to
the exploded drawings and relevant list. Once
you have identified your codes, send a
standard written order to the manufacturer,
mentioning clearly the model, serial number,
feed voltage and frequency of your appliance
and, of course, including the code and
description of the spare part you need.
