How to Fix / Troubleshooting

  • Inspect harness: Check the wiring between the main control board and the circulation pump for cuts, pinches, or loose connectors.
  • Check for moisture: Look for water ingress around the pump connector and dry thoroughly.
  • Reset appliance: After inspection, reconnect power and attempt a short cycle.
