wash sequence value then the temperature
of the wash bath will be too high.
3. Check the water temperature
4. Check if the temperature sensor is
functioning
5. Check if the heating contactor stays closed
(check voltage to contactor coil.)
6. Check the output relay that powers
the heating contactor
7. Check the output relay that powers
the heating contactor
FAILURE 18: THE OVERCURRENT SECURITY
When the motor overcurrent security has tripped the motors are switched off. The contact will be closed
again automatically after some time.
It is possible that when fault 18 is generated that not the thermal overcurrent security has tripped but the
thermal security of Motor 1 and 2 at the same time. The occurrence of this fault is exceptional (the thermal
contact is only checked when an output relay for a motor is on).
DIAGNOSE:
1. Check if the overcurrent security is open.
2. If the overcurrent security is not closing
after 15 minutes.
3. If the overcurrent security is not open
4. Check the continuity of the wiring
FAILURE 19: M1
When the motor overcurrent security has tripped the motors are switched off. The contact will be closed again
automatically after some time (the thermal contact is only checked when an output relay for a motor is on).
DIAGNOSE:
1. Check if the thermal security of the wash &
low spin motor is open
2. Check if the temperature in the cabinet of
the wash machine is becoming too high
during a hot wash with a very long
programmed wash time
3. If the thermal motor security is not closing
after 15 minutes.
4. Check the continuity of the wiring

WASH + LOW SPIN MOTOR SECURITY
If the temperature of the supplied hot water is too high:
decrease the temperature of the hot water
If the temperature sensor is defective:
replace the temperature sensor
If the heating contactor stays closed : Replace the
heating contactor
If the relay stays closed and the relay is broken,
replace the electronic board
If the relay is not broken, but receives a not allowed
signal from the electronic board, replace the electronic
board
If the overcurrent security is open, within 15 minutes
the security will close automatically.
If a motor is defective: the security can go open again
when you restart the washing machine.
If it was only a temperature problem and the motor is
not defective: the overload security will not trip again.
The overcurrent motor security will be probably
defective.
Check if both motor securities are open.
If both motor securities are open then there is a major
motor problem.
If the wiring is not continuous: repair the wiring
If the thermal security is open, within 15 minutes the
security will close automatically.
If a motor is defective : the security can go open again
when you restart the washing machine.
If it was only a temperature problem and the motor is
not defective: the overload security will not trip again.
While the machine is washing : the motor is heating
up. When the ambient temperature is becoming
important and the motor can't loose it's energy for a
long period then the thermal contact can trip.
Change the program or lower the ambient
temperature.
The thermal motor security will be probably broken.
If the wiring is not continuous: repair the wiring
