How to Fix / Troubleshooting

Safety first: Unplug the appliance before removing panels.

  • Inspect wiring harness: Check the cable bundle from the main control board (usually in the door) down to the circulation pump. Look for pinched, cut, or burnt wires.
  • Check connectors: Reseat the motor connector and the corresponding connector on the PCB to ensure good contact.
  • Run a test cycle: After reseating, run a short program and observe whether the error reappears during wash phases.
  • Component testing: If the error persists, the circulation pump or control board may be failing intermittently. Testing requires electrical measurements under load; this is best done by a professional.
