J10 Maintenance
The 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, careful and periodical machine
maintenance is advisable in order to minimize service
interruptions.
Therefore, it is advisable to:
• Descale the booster, inner surfaces of the tank and
the machine's pipes once or twice a year (call the
After-Sales Service).
• Every month descale the prewash, wash and rinse
jets with vinegar or scale remover.
• The internal tube of the peristaltic rinse aid and
detergent dispenser must undergo periodical main-
tenance (once or twice a year).
It is also advisable to sign a preventive and sched-
uled maintenance contract with the After-Sales
Service.

J10.1 Preventive maintenance

The preventive maintenance call can be activated (call
the After-Sales Service).
When the set number of cycles (e.g. 20000) has been
reached, a call After-Sales Service message appears
on the display.
This message suggests calling a specialized techni-
cian, for a general check of the equipment.
