Possible Causes
Shorted motor, Shorted triac or power transistor on PCB, Damaged motor harness, Power surge damage
How to Fix / Troubleshooting
Safety first: Unplug the washer immediately if you smell burning or see smoke.
- Inspect motor and wiring: Access the motor and harness. Look for melted connectors, burnt wires, or signs of arcing.
- Check drum movement: Ensure the drum turns freely by hand; a seized drum can overload the motor and control.
- Test motor: Use a multimeter to check for shorts between motor windings and chassis ground. Replace the motor if shorted.
- Control board: If the motor is not shorted but E51 persists, the motor triac or driver on the main PCB is likely damaged. Replace the PCB; this is typically a technician-level repair.
