Error codeC7

What C7 says
The code means the circuit for the water temperature sensor is no longer working.
Owner step
Cut power at the circuit breaker for around 30 seconds.
Reset the dishwasher.
Contact service if the code stays.
Do not confuse with these
C6 reports that the water itself is too cold, whereas C7 is about the sensor circuit. C8 concerns a blocked detergent cup, and LEAK DETECTED indicates a possible leak.
San Francisco dishwasher service
For a C7 that comes back after the breaker reset, call (415) 729-2045 and ask for dishwasher service in San Francisco or the Bay Area. Give the model number and say if the reset helped even briefly.
Model compatibility: GE reuses codes across series and model years, so C7 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
