FAILURE 20: M2 DISTRIBUTION + HIGH SPIN MOTOR SECURITY
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
distribution and high spin motor is open
2. If the thermal motor security is not closing
after 15 minutes.
3. Check the continuity of the wiring
FAILURE 21: OVERFLOW FAILURE
When the water level is raising above the hole of the overflow tube: message 21 will be displayed.
DIAGNOSE:
1. Check if the overflow hole and tube isn't
blocked
2. Check if the drain tube isn't blocked
3. Check the water inlet valves
4. Check the output relay that powers the inlet
valve
5. Check the output relay that powers the inlet
valve
FAILURE 22: FLUSH FAILURE
When the flush function is active and the machine is loosing 7 cm water then the drain will be opened.
Message 22 will be displayed.
DIAGNOSE:
1. Check if the drain valve is not losing water
2. Check if the machine is not losing water
FAILURE 23: DEFECTIVE PCB TEMPERATURE SENSOR
The temperature of the electronic board is measured. This value is used as a reference to adjust the water
temperature and the water level.
When the on-board temperature sensor is measuring wrong then the water level and water temperature will
show a value that is slightly different from the correct value. Fault 23 is only written to the log register when
the power is switched off.
DIAGNOSE:
1. Check the electronic board visually
2. If the fault is persistent
112
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.
The thermal motor security will be probably broken.
If the wiring is not continuous: repair the wiring
If the overflow tube is blocked: repair the tube
If the drain tube is blocked: repair the drain tube
If the water inlet valves are broken: replace the water
inlet valves
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 drain valve is defective: replace the drain valve
If the machine is losing water: replace the defective
parts
If you see some damage : replace the electronic
board
Replace the electronic board
