Possible Causes

Improper drain hose installation causing siphon, stuck drain pump relay on control board, drain pump stuck on due to wiring short

How to Fix / Troubleshooting

Safety First: Turn off power before working under the sink or on wiring.

Check drain hose:

  • Verify the hose is not routed downward from the dishwasher to the drain without a high loop.
  • Secure the hose to the underside of the countertop or use an air gap as per KitchenAid instructions.

Listen for drain pump:

  • Start a cycle and listen: if the drain pump runs continuously even when the unit should be washing, the pump relay or wiring may be stuck.

Corrective action:

  • If hose routing is correct and the pump still runs at the wrong time, the main control board or wiring harness likely needs professional diagnosis and replacement.
