Most people can clear this one at home with simple checks.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix GE C6

  1. Run the hot tap first

    Before starting the dishwasher, run the hot water at the kitchen sink until it is hot.

  2. Adjust your water heater

    Make sure the water heater is set high enough to deliver at least 120°F (49°C), and avoid showers or laundry at the same time as the dishwasher.

  3. Use longer cycle options

    Choose options that add heating time, such as a higher-temperature wash, if your model has them.

When to call a technician

If the water at the sink is hot enough and C6 still appears, schedule service to check the temperature sensor.
