What Does Error C6 Mean?
The GE Dishwasher C6 error indicates a low incoming water temperature, preventing proper operation. This code often appears alongside poor wash performance and may cause the dishwasher to halt its cycle until the water reaches a minimum temperature of 120°F.
Common Symptoms:
- Dishwasher displays C6 code on control panel
- Poor wash performance due to insufficient water temperature
- Dishwasher may not proceed with wash cycle until water is sufficiently warm
Possible Causes
- Low incoming water temperature (high)
- Inadequate hot water supply due to concurrent use of hot water elsewhere (medium)
How to Fix Error C6
DIY Fix Ensure hot water supply is adequate
- Before starting the dishwasher, run the hot water faucet at the adjacent sink until the water is at least warm/hot.
- Avoid using other appliances or fixtures that draw hot water (e.g., washing machine, shower) while the dishwasher is running.
- Restart the dishwasher after ensuring hot water availability.
Technician Only Inspect water supply and heating components
- Verify that the household hot water heater is set to an adequate temperature.
- Check for kinks or restrictions in the hot water supply hose.
- Confirm that the dishwasher’s internal components that influence temperature regulation (if present on the specific model) are functioning properly.
Parts needed: Hot water supply hose, Household water heater (settings), Dishwasher inlet components
- If the C6 code persists after verifying adequate hot water supply and usage adjustments
- If there appears to be an issue with internal temperature sensing hardware on models where applicable
