The Pressure Sensor Assembly is an OEM part for GE dishwashers. It monitors the water level within the dishwasher, ensuring the correct amount of water is used during each wash cycle for optimal cleaning performance.

Causes of a bad pressure sensor assembly can include wear and tear over time, clogs or debris obstructing the sensor, electrical issues, or damage to the sensor housing. Malfunctioning sensors can result from exposure to hard water minerals or detergent residues that affect the sensor's accuracy.

Symptoms of a bad pressure sensor assembly include:

Dishwasher not filling with water properly
Overfilling or underfilling with water
Error codes related to water levels
Dishes not being cleaned effectively

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

DISHWSHER WILL DRAIN OUT ALL THE WATER. BUT WILL CONTINUE TO DRAIN AND EVENTUALLY GIVE ME A Ftd error code. But all the water is completely drained. would i need a new pressure sensor?

Thanks for your question, Kirk. This could be an issue with the pressure sensor (part # WD21X25468 - WD21X25468) or a control issue (part # WD21X32938 - WD21X32938).
