8 MALFUNCTIONS SHOWN ON THE DISPLAY (FOR THE TECHNICIAN)

The dishwasher is able to identify a number of malfunctions and show them on the display. If the problem
persists after the dishwasher has been switched off and back on, proceed as described below:
Tank temperature
04
probe malfunction
Tank water filling
malfunction
05
Water pump-out
malfunction
06
Boiler does not heat up
as expected.
23
Boiler temperature
24
probe malfunction
Boiler water filling
malfunction
25
Tank temperature probe disconnected or not working.
- The tank wasn't filled in the expected time: check the water supply
tap, the dynamic supply pressure, cleanliness of the inlet water filter,
cleanliness of the rinse nozzles, any damage of the water charging
hose. If the problem still occurs during the "FILL":
- Work level tank pressure switch damaged (it always detects "empty":
check if the tank safety pressure switch starts operating).
- Leakage from the tube connected to the air trap; if the problem is not
solved, it occurs during the work program.
- vent valve of the drain pipe obstructed with dirt: with siphonage, the
tank gets completely empty at the end of a washing program.
Check:
- filter cleanliness; obstructions, bending and narrowing of the drain
pipe.
- possible obstructions of the drain pump (blocked with a foreign body).
In case the problem is not solved, please contact the After-Sales
Service.
The problem may be occurring because water is continually entering
the tank (the causes are as for "Er 05" – see above). If the boiler heating
element is damaged, this might be due to operation with no water in
the boiler - the pressure switch is indicating full even with the boiler
empty: - damaged boiler heating element – contactor failure - open on
boiler safety thermostat side. - boiler temperature probe faulty or
incorrectly positioned - motherboard relay failure, Important: If the
boiler heating element is damaged, this might be due to operation with
no water in the boiler, pressure switch continues to give full reading
even with boiler empty: check boiler air trap and/or relative pressure
switch and replace if necessary.
Boiler temperature probe disconnected or not working
The boiler wasn't filled in the expected time: check the water supply
tap, the dynamic supply pressure, cleanliness of the inlet water filter,
any damage of the water charging hose, or check the following in this
order:
- faulty boiler pressure switch (it always detects "empty"),
- leakage or unbinding of the tube (water runs inside the tube)
- menu service wrong setting "rP"
