Confirmed: GE Appliances documents PrS as a dishwasher pressure-sensor signal problem where the cycle cannot start or will cancel, with service recommended.
Can you keep using it?

When to stop
Stop using the dishwasher when PrS appears, especially if cycles cannot start or cancel immediately.
When to call a professional
GE Appliances recommends service for PrS.
Safe checks
- Confirm the display reads PrS.
- Do not keep restarting cycles that cancel immediately.
- Record whether the dishwasher cannot start or cancels after starting.
Confirmed by the manufacturer
- The pressure sensor is sending an invalid signal to the control.
- The dishwasher cannot start a cycle or the cycle will cancel.
- GE Appliances says the likely issue is harness or sensor related and recommends service.
Commonly associated with this fault
- A repeated immediate cycle cancel can fit the official PrS behavior.
Not confirmed for this exact model
- Do not identify the exact failed harness, sensor, or control board from PrS alone without service diagnosis.
Reset instructions
No reset procedure is published here because the current source does not document one for this scope.
Do not repeatedly reset or restart a dishwasher that continues to show PrS.
Information to collect before calling service
Record model label, exact PrS display, whether the cycle fails to start or cancels, and any recent water or service event.
