GE Dishwasher C7 code: Temperature sensor circuit fault
The circuit for the dishwasher's water temperature sensor has stopped working, so the control can't tell how hot the water is.
Most common causes
- Failed temperature sensor (thermistor)
- Loose or damaged sensor wiring
- Control board fault
What you can safely check yourself
- Turn off the dishwasher's power (breaker or plug) for 30 seconds, then turn it back on and run a cycle.
Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
