In case of particularly heavy usage it is recommended to perform a cleaning of the filter every 30-40 wash cycles in
order to maintain the machine in operative conditions; Use “partial Tank draining” in order to perform these
cleanings.
Remove the filters (it is sufficient to lift them out of their lodgings as shown
in the figure), making sure that greasy residues do not fall into the opening
underneath the filters. Clean away the residues and rinse the filters
abundantly before correctly reinserting them; Do not utilize pointy or sharp
objects for cleaning.
Be sure to remove eventual hardened calcium deposits in order to avoid
their accumulation;
‐ Clean the surfaces well and frequently with a damp rag; use neutral,
non-abrasive detergents which do not contain chlorine-based
substances. Corrosive products can damage stainless steel.
In order to avoid drops or vapors damaging the steel surfaces, do not even use the above-indicated products for
the cleaning of the flooring beneath or around the dishwasher.
10.2 Periodic checks
Disassemble the sprinklers (lower and upper 2-4) by removing the central screw (4); unscrew the caps at the two
far ends of the rinsing sprinklers (7).
Clean the holes and the nozzles under a stream of clean water. Do not use utensils which could cause damage.
Carefully reassemble the sprinklers.
Clean the outside of the machine with neutral soap and a damp cloth. Rinse and dry with care.
10.3 Prolonged disuse
If the use of the dishwasher is not foreseen for a relatively long period of time it is necessary to drain the
detergent and rinse-aid dispenser in order to avoid crystallization and pump damage:
Remove the suction
tubes from the detergent and rinse-aid containers and emerge them in a container filled with clean water. Perform a
few wash cycles and drain the machine completely.
Finally, turn off the main switch and close the water supply faucet. The detergent and rinse-aid suction tubes will be
placed back in the containers when the machine is ready to be put back in use, taking care so as not to invert
the tubes (red tube = detergent; transparent tube = rinse-aid).
Do not leave the device on, inactive and in disuse for long periods of time.
