GE dishwasher PrS code

Bad pressure-sensor signal. Reseat the plug before a new pump.

Dishwasher
Sensor
Check the harness

GE dishwasher PrS means the pressure sensor signal is invalid. The control is not reading a normal water-level signal from the sensor. A loose harness at the sensor causes PrS more often than a failed drain pump. Unplug the dishwasher, find the pressure sensor, and confirm the plug is seated. PrS that returns with a tight harness usually needs the sensor, not a new pump.

How to fix PrS

Unplug the dishwasher or turn off its breaker.
Locate the pressure sensor and confirm the wire plug is fully seated.
Look for a pinched or corroded harness between the sensor and the control.
Restore power and run a rinse. PrS should stay off if the plug was loose.
Replace the pressure sensor if PrS returns and the harness is intact. Do not start with the drain pump.

Call a pro when: Call a technician if the harness is damaged or PrS returns after the sensor plug is confirmed seated.
