How to Fix / Troubleshooting

Safety First: No internal repair is required if this is a diagnostic indication.

  • Allow cycle to complete: If you intentionally started diagnostics, allow the dP phase to finish draining.
  • Exit diagnostic mode: Cancel the cycle by pressing and holding the Cancel or Start/Cancel button for 3–5 seconds, then wait for the pump to stop.
  • Power reset: Turn off the breaker for 1 minute, then restore power to return the dishwasher to normal operation.
  • Consult service manual: If dP reappears unexpectedly, refer to the technical sheet behind the toe-kick or contact a technician.
