The motor controller indicates the thermal
protector of the motor has triggered.
If the power is on, be very careful when
working on the machine.
First verify that:
• the machine is not overloaded
• the ventilation openings of the machine are
not blocked
• the external temperature is not very high
• the motor is not abnormally warm
• the drum doesn't rotate stiffly
Switch off the machine for at least 30 seconds to
ensure the motor controller has been completely
reset. Then try to start the machine again. If the
error returns, troubleshoot as follows:
1. Switch off the machine and verify that the drum and
motor operate smoothly.
Drum/motor OK Heavy operation of the drum/
motor
Defective bearings in drum
or motor, or there is an
object between the outer
and inner drum. Inspect and
remedy.
2. Wait for at least 10 minutes to allow the motor to cool
down. Then switch on the machine again. Enter the service
programme and run the motor clockwise at low washing
revolutions (code 25). Verify whether the error indication
immediately returns.
No error indication Immediate error indication
3. Switch off the machine. Undo the contactor at
X3 on the motor. Use an ohm meter to measure
the resistance between the contactor and the
motor at X3:7 - 9.
