C6 on a GE dishwasher says water entering the machine is too cool; the manual gives faucet, water heater and cycle-option tips.
Model compatibility: GE reuses codes across series and model years, so C6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The water temperature is too low.
C6 means the water temperature is too low. According to GE, the water coming into the dishwasher should be at least 120 degrees F.
What the manual suggests
Run the faucet next to the dishwasher before you start it, to purge cold water from the line.
Adjust the water heater temperature.
Skip the washing machine and showers while the dishwasher is running.
Pick options on the dishwasher that make it run longer, which adds more heat.
Other water-related codes
A water temperature sensor issue is a different code, C7. If the dishwasher is not getting enough water at all, see H2O.
