GE Dishwasher C1 Error Code: What It Means & How to Fix It

C1 = Drain pump-out took longer than 2 minutes. C1 on a GE dishwasher means pumping water out took longer than two minutes. GE's fix list: clean the air gap, reposition or replace the drain hose, and run the disposal.

Can you fix it yourself? Yes

Check your model: Error codes can mean different things on different GE models. Find your model number (usually on a sticker inside the door or lid, or on the back) and confirm the code in your user manual.

Safety first: Unplug the appliance (or switch off its breaker) before you remove panels, filters or hoses. Turn off the water supply valves before you disconnect any hose, and keep a towel and shallow pan handy. Never work on wiring, gas lines or sealed refrigerator systems yourself.

Repair or replace?

If the appliance is under warranty, call GE first, since a repair may be free. Out of warranty, a common rule of thumb is to compare the repair quote with the cost of a new unit and the appliance's age before deciding.
