GE Dishwasher Error Code: C6
Water temperature coming into the dishwasher should be at least 120 degrees F. Run the faucet adjacent to the dishwasher prior to starting the dishwasher to purge any cold water from the line. Adjust the water heater temperature. Don’t use the washing machine or take showers when using the dishwasher. Use options on the dishwasher to cause the machine to run longer and thus add more heat.
