• Carefully clean the washing and rinse jets and
clean everything with hot water and neutral deter-
gent/detersive, if necessary using a soft brush or
sponge. Do not use sharp implements to clean the
nozzle holes, which could otherwise be damaged.
Upon completion of cleaning operations, replace the
parts removed previously.
I9.2 Exterior cleaning
Before carrying out any cleaning operations, turn off
the power at the mains.
IMPORTANT
Clean the stainless steel surfaces using warm
soapy water; never use detergents containing
abrasive substances nor steel scrapers, common
wire wool, brushes or scrapers; rinse thoroughly
using a wet cloth and carefully wipe dry.
Clean the control panel using a soft damp cloth
and a neutral detergent if necessary.
Do not wash the appliance using direct or high-
pressure water jets.

To reduce the emission of pollutants into the environ-
ment, clean the appliance (externally and where
necessary internally) with products having a biodegra-
dability of over 90%.
Leave the hood raised whenever the appliance is not in
use.
I10 Long idle periods
Whenever the dishwasher is not going to be used for a
long period of time (e.g. one month), carefully carry out
the following instructions.
• Close the water supply cock.
• Completely drain the tank.
• Remove and carefully clean the filters.
• Completely drain the
hoses, removing them from the containers. Repeat
the procedure described in the paragraph "Manual
activation" at least 3 times.
• Completely drain the boiler.
• Clean the inside and outside of the machine as
indicated in par. I9.1 "End of service and daily inter-
nal cleaning" and I9.2 "Exterior cleaning".
• Spread a film of paraffin oil over the steel surfaces.
When using the machine again, follow the indications
in par. I4 "Daily activation of machine".
I11 Maintenance
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 tech-
nical assistance).
• Every month descale the wash and rinse jets with
vinegar or scale remover.
• The internal hose of the rinse-aid and detergent
peristaltic dispenser should undergo periodic main-
tenance (once or twice a year).
• If present, clean the finned coil of the energy saving
device once or twice a year (call technical assis-
tance).
It is also advisable to stipulate a scheduled pre-
ventive maintenance contract with technical assis-
tance.
I11.1 Preventive maintenance
The preventive maintenance call can be activated (call
technical assistance).
On reaching the set number of cycles (e.g. 20000), a
technical assistance call message appears on the dis-
play.
This message suggests calling a specialized techni-
cian, for a general check of the equipment.
