Washing results are
unsatisfactory
The washing nozzles are obstructed
or the rack does not rotate.
Clean the nozzles carefully, and check the right positioning of
the wash-arm, tightening firmly.
Foam is present.
Use no-foam detergents or reduce the dose in use. Check the
rinse-aid dosage.
Fats or starches not removed.
Insufficient detergent concentration.
Filters are dirty.
Remove filters, clean with brush under a jet of water and
replace in original position.
Check tank temperature (which must
be between 50°C and 60°C).
Adjust the thermostat or check correct heating element opera-
tion.
Wash time insufficient for the type of
dirt.
Select a longer wash-cycle, if possible, otherwise repeat the
wash cycle.
Wash water is dirty.
Drain the tank water, clean the filters; refill the tank and replace
the filters correctly.
The objects are not properly
dried.
Not enough rinse aid.
Increase dosage by turning the dispenser screw (see par.
"Rinse aid dispenser").
The rack is not suitable for the
objects.
Use the suitable rack which gives the objects an inclined
position so that water can rinse away.
The washed items may have been
sitting in the wash chamber too long.
As soon as the cycle stops, remove the rack with the objects so
that they can dry more quickly in the air.
Rinse temperature under 80°C.
Check the boiler thermostat temperature.
Surface of objects too rough or po-
rous for material wear.
Replace type of the objects used. If the dirt on the object is dry
and old, soak before washing.
Streaks and spots on glas-
ses and dishes
Too much rinse-aid chemical.
Reduce the rinse aid amount by turning the micrometric
dispenser screw (see par. 2.4 "Rinse aid dispenser").
Too hard water.
Check the water quality. Water must not exceed 5-8°f in
hardness

overload device.
Connect the machine on a own overload device (call Service).
A machine safety device was
triggered.
Check the electrical devices (call Service).

the wash stage and starts
refilling water.
