What we can confirm
Code C6, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
C6
The water temperature is too low. GE is specific about the number: the water coming into the dishwasher should be at least 120°F, and in a house where the kitchen is a long way from the heater it will not be on the first fill.

About GE dishwasher error code C6
What C6 means, in the maker's own words
The water temperature is too low. GE is specific about the number: the water coming into the dishwasher should be at least 120°F, and in a house where the kitchen is a long way from the heater it will not be on the first fill.
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
- Run the faucet next to the dishwasher before starting it, to purge the cold water sitting in the line. This is GE's own advice and it costs nothing.
- Check the water heater setting.
- Do not run the washing machine or take showers while the dishwasher is filling — GE names this too, and in a busy household it is the real cause.
- Use the options that make the cycle run longer, which adds heat.
- If the water arriving is genuinely 120°F and the code persists, the temperature sensing circuit is next — that is C7.
Where this goes next
The job this usually becomes is 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 and describe what the display is doing before booking anything.
