Can I fix GE Appliances code C1 myself?

Start with these safe checks: Clean the air gap (the small cap next to the faucet, if you have one). Check under the sink that the drain hose isn't kinked or crushed. Run the garbage disposer to clear it out, then try the cycle again. If C1 keeps coming back after these checks, GE recommends contacting service.

When should I call a technician for code C1?

If C1 keeps coming back after these checks, GE recommends contacting 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.
