How to Fix / Troubleshooting

Safety first: Unplug the washer before accessing control boards.

  • Reseat communication cables: Locate the harness connecting the main control to the motor control. Disconnect and reconnect both ends, ensuring a firm fit.
  • Inspect harness for damage: Look for pinched or cut wires along the route. Repair or replace as needed.
  • Replace suspect board: If wiring is intact, replace the motor control board first (most common). If E5C persists, replace the main control board.
  • Run diagnostics: After replacement, enter diagnostic mode and run a full test to confirm communication is restored and E5C is cleared.
