How to Fix / Troubleshooting

Safety first: Disconnect power before working near the motor.

Steps to check:

  • Inspect harness: Remove the rear panel and carefully inspect the wiring harness from the motor to the PCB. Look for flexing points where wires may break internally.
  • Reseat connectors: Unplug and replug the motor connector and the PCB connector for the motor harness to ensure good contact.
  • Check for moisture: Ensure there is no water or condensation around the motor or connectors.
  • Test empty spin: Run a spin-only cycle with no load to see if 3E1 returns.

When to stop: If the error persists, the hall sensor or entire motor assembly may need replacement. This is a moderate to advanced repair.
