I6 Maintenance
IMPORTANT
Before servicing, disconnect the electrical service
and place a red tag at the disconnect switch to indi-
cate work is being done on that circuit.
Inspection and maintenance intervals depend on the
actual machine operating conditions (total wash hours)
and ambient conditions (presence of dust, damp, etc.),
therefore precise time intervals cannot be given. In any
case, to minimize interruptions of the service, careful
and periodical machine maintenance is advisable.
Therefore, it is advisable to:
• Descale the boiler, inside surfaces of the tank and the
machine piping once or twice a year (call technical
assistance).
• Every month descale the prewash, wash and rinse
jets with vinegar or scale remover.
• Once or twice a year clean the finned coil of the CU
(call technical assistance).
It is also advisable to stipulate a scheduled preven-
tive maintenance contract with technical assistance.
I6.1 Preventive maintenance
The preventive maintenance call can be activated (call
technical assistance).
On reaching the set number of working hours (e.g.
5000), a technical assistance call message appears on
the display.
This message suggests calling a specialized technician,
for a general check of the equipment.

I8 Troubleshooting
THE DISHWASHER DOES NOT WASH PROPERLY
1. Check the suction filter and carefully clean it if
dirty.
2. Make sure the wash jets are not clogged by solid
residuals.
3. Make sure the initial quantity of detergent and/or
subsequent additions are correct.
4. Make sure the modules making up the machine
respect the recommended values given in the
technical data table.
5. Make sure the dishes are correctly placed in the
racks.
GLASSES AND DISHES ARE NOT PROPERLY
DRIED
1. Make sure there is rinse aid in the container and
top-up if necessary.
2. Make sure the water temperature of the rinse mod-
ule is between 176°F and 194°F (80°C - 90°C).
3. If present in the machine, check operation of the
drying module (that hot air comes out).
4. Make sure the curtains are correctly positioned.
5. Make sure the dishes were not immersed in foamy
detergent (e.g. hand wash detergent) before being
put in the machine.
CONDENSATE ON GLASSES
1. Make sure there is rinse aid in the container and
top-up if necessary.
STAINS ON GLASSES
1. Only use “non-foaming” products for professional
dishwashers.
EXCESSIVE FOAM IN THE TANK
1. Make sure the washing module water temperature
is not below the minimum recommended value
given in the technical data table.
2. Make sure the tank has been cleaned with suitable
detergents.
3. Empty the tank and carefully rinse before resum-
ing work.
4. If a foaming detergent was used, empty and refill
the tank with water until the foam has been
removed.
