# GE dishwasher error code C7

### What C7 means, in the maker’s own words

The water temperature sensor circuit has become inoperative. Where C6 is about the water, this is about the appliance’s ability to measure it — so no amount of running the faucet will change it.

### Where this code actually appears

On the control panel, and usually with a sound. GE describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.

### What to do about it

- Disconnect the power at the circuit breaker for about 30 seconds and reset the dishwasher.
- If the code returns, it is a service call: the sensing circuit is measured rather than reset repeatedly.
- Worth noting: a machine that cannot read its water temperature will also wash badly, so this often arrives as two complaints.

### Where this goes next

The job this usually becomes is [dishwasher wash performance service](/services/dishwasher-wash-performance-service/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 306-2503](tel:+13053062503) and describe what the display is doing before booking anything.
