Can I fix GE Appliances code C6 myself?

Start with these safe checks: Run the kitchen faucet until the water is hot before you start the dishwasher. Avoid running the washing machine or showers while the dishwasher runs. Check the water heater setting, and use options that make the cycle run longer to add heat. Don't set a water heater so hot that it scalds. If the code continues with hot water at the sink, schedule service.

When should I call a technician for code C6?

Don't set a water heater so hot that it scalds. If the code continues with hot water at the sink, schedule service. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
