Frigidaire Professional Overfill / Water Level Control Failure

Dishwasher overfills with water or water level is too high in the tub.

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 or blocked pressure sensor hose, Faulty water level sensor, Inlet valve stuck open mechanically, Control board not shutting off fill

Safety First: Turn off power and water immediately if overfilling is observed.

Shut off water: Close the supply valve under the sink to stop filling.
Inspect pressure hose: Access the pressure sensor and clear any blockage in the hose as described in the i40 section.
Check inlet valve: If water continues to flow into the tub with power off, the inlet valve is stuck open and must be replaced.
Test sensor: Replace the water level/pressure sensor if it does not respond correctly after cleaning.
