KitchenAid Overfill Condition / Water Level Sensing Fault

Dishwasher overfills or shows a water level too high error; may start draining immediately after filling.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck water inlet valve, blocked or failed pressure sensor (if equipped), siphoning through drain hose, main control misreading level

How to Fix / Troubleshooting

Safety First: Turn off power and shut off water supply immediately to prevent flooding.

Check drain hose routing:

Ensure the drain hose has a proper high loop or air gap to prevent siphoning.

Inspect inlet valve:

With power off, disconnect the water inlet valve wiring. Turn water supply on briefly. If water still flows into the dishwasher, the valve is stuck open and must be replaced.

Check for debris in level sensing system:

Some models use a pressure sensor or float. Inspect the float (if present) inside the tub to ensure it moves freely and is not stuck by debris or scale.
Clean around the float and test its movement.

If problem persists:

The pressure sensor or main control may be faulty and should be diagnosed by a professional.
