Instructions For Maintenance And Repair Personnel; Scheduled Maintenance And Spare Parts - grandimpianti WR-EC 8 Mode D'emploi

Measures to be taken in case of a
voltage drop
If a voltage drop longer than 3 sec. occurs
during a wash cycle, on being re-energised
all the luminous devices the machine is
fitted with (wash step LEDS, time, cycle and
temperature DISPLAYS) are reset: they flash
for one minute with all functions disabled.
As soon as normal work conditions are
restored the cycle will be resumed from the
step that was underway when the voltage
drop occurred and displays will resume their
normal functions. Conversely, if the door is
open when the machine is re-energised, the
cycle will be aborted.
ATTENTION If the ON - OFF switch is
actuated to turn machine off after the
cycle has been started, the machine will
behave as if a voltage drop has occurred.
ATTENTION: WHEN ONE OR MORE
ALARMS APPEAR ON DISPLAY
DURING MACHINE OPERATION, IN
ORDER TO AVOID
DAMAGE, REMOVE MISFUNCTION
SOURCES (IF POSSIBLE) BEFORE
STARTING A NEW CYCLE OR
CONTACT THE AUTHORISED AFTER-
SALES SERVICE OR DEALER.
7.8 INFORMATION ABOUT SPECIAL
MEASURES FOR USE AND
PROTECTION
When carrying out the first cycle, verify the
following:
- Soap dispensers must stay clean:
dispenser A after taking in pre-wash water;
dispenser B after taking in wash water;
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.
- The operator must be able to check soap
compartments with ease. Place a platform if
necessary.
- Make certain that laundry trolleys are lower
than the door bottom edge.
- 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 HOT WATER, COLD
WATER AND STEAM TAPS ARE
CLOSED (THE LATTER APPLIES TO
STEAM-HEATED MACHINES ONLY).
THE DRUM MUST BE STILL AND
DRAINED AND THE TEMPERATURE
INSIDE MUST NOT EXCEED 40
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.
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.

AND ORDERING SPARE PARTS

8.1 REMOVE THE LID
To reach the machine electrical parts, take
off the screws fastening the lid to the back
panel and the soap dispenser. Then lift the
rear part of the lid and pull it to the front by
approximately 5 cm.
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 hot 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 microswitch disconnects the auxiliary
circuit from the power mains and so stops
the appliance.
- Motor overload cutout that cuts off power
to the motor winding.
- Air-break system in the soap dispenser,
which avoids pollution of the water mains in
case of a depression.
- Normally open drain valve, which enables
safe door manual opening.

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 HOT 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).
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.
YEARLY INSPECTION
SERVICING
Check that machine floor-anchoring nuts
are securely fastened.
Check the wear of belts and replace them if
necessary. If more than one belt is worn-out,
replace the entire set.
Make sure that the safety devices are working
properly (e.g. door microswitch).
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.
