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.

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.
