GE Dishwasher C1 error code
C1 shows up when the dishwasher's drain pump ran for more than two minutes during pump-out. That tells the control the machine is struggling to get water out of the tub. It almost always points to a blockage somewhere in the drain path rather than a failed part.

How to fix GE C1 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Clean the air gap
Remove the air gap cap (usually mounted on the sink deck or countertop) and clear out any debris or buildup inside it, then replace the cap. - Check and reposition the drain hose
Make sure the drain hose is not kinked, pinched, or pushed too far down the standpipe, and reposition it so it forms a proper high loop. Replace it if it is damaged.Safety warning: Turn off power at the circuit breaker before reaching under the sink to handle the hose. - Run the garbage disposer
Run the disposer briefly with water flowing to clear out food waste that can block the dishwasher's drainage into the disposer.
When to call a technician
- The C1 code returns after you have cleared the air gap, hose, and disposer
