Genuine OEM dishwasher overflow/float switch. The switch shuts off the water-fill valve if the water level becomes too high before the timed fill cycle ends.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Water fill stops or does not begin when the flood float is stuck in its raised position.
• On affected GE models, a C4 fault can indicate a stuck or failed float switch; a clogged drain or sump can also cause that code.
• The dishwasher may not wash properly if inadequate water enters the tub.

Check Before Replacing

• Before maintenance, disconnect power at the plug or household circuit breaker.
• For applicable models with a removable flood float, remove the filters, lift the float straight up, and check that it is not bent or damaged and that debris is not blocking the sump area.
• Reinstall the float correctly and confirm it moves freely; a stuck float can prevent water from entering the dishwasher.
• If a C4 code is present on an affected GE model, check for debris around the float cover and sump before concluding that the overflow switch itself has failed.

Pro Tip

Part Details

Key Features

• Genuine OEM GE dishwasher overflow/float switch.
• Safety-related water-level control that stops fill when the flood-float condition signals excessive water level.
• Used with the dishwasher's flood-float assembly rather than as a standalone water-level adjustment component.

Installation Notes

• Disconnect electrical power before accessing or servicing the float-switch circuit.
• Verify the dishwasher model and exact part number before installation; similar-looking water-level components may not be interchangeable.
• After service, make sure the associated flood float is correctly seated, straight, and free to move without debris obstruction.
• If the repair requires access to wiring or the switch beneath the tub, follow the model-specific service information or use a qualified appliance technician.
