GE Dishwasher turbidity sensor assembly WG04F05595, Replaces WD21X10494

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Turbidity-sensor or temperature-sensor fault indications
• Dishwasher defaults to maximum fill, wash, or circulation time when the sensor signal is open, shorted, or invalid
• Poor or inconsistent heating/drying performance when the sensor’s integrated thermistor is out of range
• Wash-cycle decisions that do not match the actual soil level of the water

Check Before Replacing

• Disconnect electrical power before inspecting the sensor or wiring.
• Check that the turbidity-sensor harness connector is fully seated and that the wiring is not damaged, pinched, or corroded.
• Inspect the sensor’s exposed sensing area for heavy soil or mineral buildup; clean it carefully without scratching or damaging the sensor.
• Use the dishwasher’s manufacturer-specified consumer/service diagnostic mode, when available for the exact model, to check for turbidity or temperature-sensor faults.
• If testing electrical values, use the exact service documentation for the dishwasher model; do not condemn the sensor from a fault code alone because the harness, control, water level, circulation, or drain system can produce related symptoms.

Installation Notes

• Disconnect power and water supplies and remove the dishwasher from its installation before accessing the sensor beneath the tub.
• The service procedure requires disconnecting the sensor wire harness and loosening the hose clamp before removing the sensor from the sump.
• During installation, align the sensor tab with the sump cutout before tightening the hose clamp.
• Restore the harness connection securely and check carefully for leaks before returning the dishwasher to normal use.
