8. MAINTENANCE
Before starting any maintenance work, disconnect the appliance from the power supply.
Daily maintenance involves removing objects from the chamber and washing them with a cloth
dampened in water with a dish detergent and then wiping them off with a dry cloth. Washing under running
water as well as using a pressure washer for this purpose is prohibited.
In the case of intense use, we recommend that you clean the filters every 30-40 wash cycles in order
to ensure the proper functioning of the appliance To do this, partially drain the tank of water.
Remove the filters, making sure no fatty deposits and leftover food falls into the openings under the
filters. Clean the filters of food residue and sediment and then rinse thoroughly. Do not use sharp tools or
sharp edges to clean the filters. Make sure to also remove limescale, as this prevents the build-up of a layer on
the surface of the filter.
The surfaces of the filters should be cleaned thoroughly with a damp cloth and neutral (non-
aggressive) detergents with no chlorine content and agents that do not cause corrosion and mechanical damage
to stainless steel surfaces.
In order to prevent the formation of corrosion spots on the stainless steel, avoid using harsh detergents
containing chlorine and agents that cause corrosion or mechanical damage to the stainless steel surfaces. For
cleaning floors and immediate surroundings, only use detergents that do not cause damage to stainless steel.
Once a month you should make sure whether:
•electrical connections are made correctly
•the power cord is not damaged;
•all components of the appliance are working properly,
Remove the nozzles (figure 13) (upper and lower 2-4) by unscrewing screws (4). Unscrew the caps (7) at the
two ends of the nozzles.

Figure 13
•Clean the outside of the appliance using soap and a damp cloth and then thoroughly rinse and wipe dry.
Service the appliance once a year to verify its degree of wear and detect possible failures of components and
parts. If you detect any damage, it should be removed by qualified technical personnel (technical services).
Technical service should pay particular attention to:
•the condition of heating elements
•the condition of heating elements' safeguards
•wear and tear of the appliance
•insulation quality
Although no special program of periodic inspections has been developed, it is recommended that the correct
functioning of the appliance and its safety be checked by a maintenance employee twice a year. Any damage or
failure resulting from the user's non-compliance with this manual, as well as failure to comply with existing
legislation and standards, will not be considered manufacturer's liability.
Downtime in operation
When not expecting to use the appliance for an extended period of time, it is necessary to empty containers
for the washing liquid and rinse aid in order to prevent crystallization, and consequently, damage to the pump.
Accordingly, suction tubes should be removed from both containers and placed in a bowl filled with clear
water; carry out several wash cycles and then drain the tank of water.
Finally, turn off the main switch and close the water tap. Suction tubes must be connected back to the
containers only when the appliance goes back into use (the transparent tube goes into the washing liquid
container, and the transparent one with blue lagging into the rinse aid container).
It is forbidden to leave the appliance on and the water valve open for an extended period of
downtime.
9. PACKING, LOADING AND TRANSPORT
The dishwasher is packed in accordance with applicable standards. Loading for transport, unloading and transit
should be done using appropriate cranes mechanisms, trucks.
