Fault-tracing

Motor does not run at all.

• Check the power supply to the motor. Check the motor´s quick connector.

• Check the motor windings with an ohmmeter for short-circuit or failure.

• Check that the motor shaft can be turned. If it can´t, the probable cause

is bearing failure. Replace the motor.

• If, right after stopping, the motor feels abnormally hot, its thermal protection has

probable tripped. Investigate the cause of the overloading. Check that motor and drum

rotate easily.

The motor protection resets automatically when the motor has cooled, after about 30

minutes. Start the machine and listen for any untoward noise.

If the motor protection trips repeatedly, it may be because of short-circuiting. Bearing

failure in the motor may be the cause.

Motor runs slow

The motor is probably operating on only two phases.

• Check that the motor´s power supply is correct.

• Remove the quick connector and use a meter to check the motor windings for failure or

short-circuiting.

Motor is very noisy or seizes

• Bearing failure, replace motor
