INSTRUCTION
HANDBOOK
WATER IN DRUM Error 6
- Waste water collector might be blocked.
- Drain valve or wiring faulty.
- Level tube probably blocked.
- Level detection function on CPU PCB faulty.
- Air vent blocked.
Error/Function Cause Action
Clean waste water collector.
- Check drain valve functioning.
- Clean or replace level tube.
Clean connection of the water
level control device.
- Replace PCB.
- Clean air vent.
The water level is higher than the
EMPTY level at start of program.
MACHINE OVERFILLED Error 7
- Transient fault or water has been added manually.
- Electrovalves are faulty.
- Level detection function on CPU PCB faulty.
- Drain machine then restart a
program or change the level in
the manual program.
- Check function of electrovalves.
- Replace PCB.
The water level is above the
set safety level during program
operation or manual operation.
NO HEATING Error 8
- Bad water seal of the drain valve.
- Elements faulty.
- Leak at water supply.
- Fault in wiring between contactor and element(s)
or heating contactor faulty.
- Temperature detection function on CPU PCB
faulty.
- Check water seal of the drain
valve.
- Switch off power supply at wall
switch. Measure resistance of
elements to see if any element is
faulty (open circuit).
- Replace faulty element.
- Check seals of water electrov-
alves.
- Check wiring and replace the
heating contactor.
- Replace PCB.
Rate of temperature incease
in water slower than minimum
value allowed.
13. Maintenance
NTC HIGH TEMP. Error 5
- This suggests short-circuit in sensor or wiring.
- Temperature sensor faulty.
- Temperature detection function on CPU PCB
faulty.
- Check the wiring temperature
sensor and replace as appropri-
ate.
- Replace temperature sensor.
- Replace PCB.
Temperature sensor indicating
a temperature above highest al-
lowable value.
NOT DRAINED Error 10
- Programmed drain time too short.
- Level tube probably blocked.
- Drain valve or wiring faulty.
- Level detection function on CPU PCB faulty.
- Increase drain time.
- Clean or replace level tube.
Clean connection of the water
level control device.
- Check drain valve functioning.
- Replace PCB
The water level is higher than
the EMPTY level after drain
sequence.
