C7
May need a pro

The circuit for the water temperature sensor is not working. A failed sensor or wiring fault is the likely cause.

GE notes that not every code appears on every model; check your owner's manual.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix GE C7

  1. Reset the power

    Switch off the dishwasher's circuit breaker (or unplug it) for about 30 seconds, then restore power and start a new cycle.

  2. Note the code and model number

    Write down the exact code, when in the cycle it appeared, and the model and serial numbers from the rating label (usually on the side or top edge of the door or tub). With nothing safe left to check yourself, this lets the technician bring the right part on the first visit.

When to call a technician

If C7 returns after a reset, schedule service.
