Troubleshooting

• Check the motor windings with an ohmmeter
Fig
to detect any possible short-circuit or fault.

• The motor winding shall have the resistance of
2,6 ohm, measured between two phases.
• Check that the motor shaft can be turned. If it
can't, the problem is probably bearing failure.
Replace the motor (see under "To replace the
motor").
• If the motor feels abnormally hot (Error code
32E) directly after it has stopped functioning,
its thermal protector has probably been
activated. Investigate the cause of the
overload. Check that the motor and drum can
revolve freely.
The thermal protector will reset automatically
when the motor has cooled. Start the machine
again and listen carefully for any abnormal
noise.
If the thermal protector is triggered repeatedly
the cause may be:
- short-circuit
- bearing failure in drum
- bearing failure in motor.
• If the motor appears to be sound, the site of
the fault will probably be the motor control.
Replace the circuit board.
