How to Fix / Troubleshooting

Safety first: Disconnect mains power. This fault involves high-voltage electronics.

  • 1. Visual inspection: Remove the top cover and inspect the main control board for obvious burn marks or damaged components near the motor control section.
  • 2. Check motor wiring: Inspect the harness from the PCB to the motor for chafing, melted insulation, or pinched sections against the cabinet.
  • 3. Do not bypass safety: Do not attempt to bypass the control board or hard-wire the motor; this is dangerous.
  • 4. When to call a technician: E51 almost always requires replacement of the main control board and sometimes the motor. This should be done by a qualified technician with proper testing equipment.
