What to do
- Reset at the breaker
Switch the power off at the circuit breaker for about 30 seconds, then switch it back on and reset the dishwasher.
When to call an engineer
If the problem persists, GE says to contact service.
A repair visit will usually check the sensor's reading with a meter, then its wiring.
Before you book
- Note the model and serial number. They're on a label on the edge of the door or the side of the tub.
- Write down the exact code, and what the appliance was doing when it appeared.
- Check whether it's still under warranty. If it is, the repair may cost you nothing.
