GE Dishwasher Error Code PrS — Pressure Sensor Fault
What this means
The PrS error code on GE dishwashers indicates the pressure sensor is sending an invalid signal to the control board. The dishwasher cannot determine the water level in the tub and will not start or will cancel the cycle. This is typically caused by a faulty pressure sensor or a damaged wiring harness.
Step-by-step fix
3 stepsReset the dishwasher
Turn off the circuit breaker for 5 minutes, then restore power. Start a cycle to see if the code clears.
Check the pressure sensor wiring
Unplug the dishwasher. Locate the pressure sensor (typically near the sump assembly). Check the wiring harness for loose connections, damage, or corrosion.
Contact a professional
If the wiring looks good and the code persists, the pressure sensor or control board likely needs replacement. This diagnosis and repair is best handled by a technician.
When to call a professional
The PrS code typically requires professional service. The pressure sensor and its interaction with the control board requires specialized testing equipment.
