How to Fix / Troubleshooting

Safety: Unplug the washer and do not attempt repeated starts, as this can damage the electrical system.

  • Inspect motor and wiring: Remove the rear panel and check for signs of burning, melted insulation, or water ingress around the motor and harness.
  • Test motor resistance: Measure motor winding resistance and insulation to earth. Replace the motor if readings are abnormal or if there is a short to chassis.
  • Dry moisture: If there are signs of leaks onto the motor, fix the leak source (e.g., door seal, tub gasket) and allow the motor to dry completely.

E51 typically requires replacement of the main control board after confirming the motor and wiring are not shorted. This should be done by a qualified technician.
