GE Appliances / General Electric Dishwasher Sensor Leak Pan WD21X20552

Genuine GE dishwasher leak-pan moisture sensor that detects water in the base pan for the dishwasher leak-protection system.

Is This the Right Part?

Common Symptoms

• False or persistent leak-detection indication when the leak pan is dry
• Dishwasher cancels the cycle and pumps out water after a leak-detection signal
• Dishwasher will not operate normally because the leak-protection system remains activated

Check Before Replacing

• Inspect the leak pan for actual water before replacing the sensor.
• If a LEAK DETECTED message is displayed, disconnect power and correct the underlying leak before condemning the sensor.
• Verify the appliance model-specific parts diagram lists WD21X20552 before installation.
