What Does Error Code C1 Mean on a GE Appliances Dishwasher?

Slow drain — pump-out during drain exceeded ~2 minutes.

C1 fires when the control monitors the drain phase and the pump fails to evacuate water within roughly two minutes, signaling restricted drainage rather than a leak or fill problem. It differs from fill/float codes because it times the pump-out specifically. On many newer touch-panel GE/Profile/Café units, the same C1 alternately flags a stuck control-panel key, so if drainage checks out, clean the panel and power-cycle before condemning the pump.

Models affected: GE, GE Profile, and GE Café dishwashers with electronic controls, including touch-UI models like GDT665SSNSS and GDP630PYRFS
What owners report: Owners commonly report C1 after installing a new garbage disposal without knocking out the plug, or when the air gap or filter clogs over time. A quick win many describe is clearing the air gap and running the disposal; on touch-panel models, a simple power-cycle sometimes clears a false stuck-key reading.

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error C1 appears? +
You often can for a cycle or two, but the drainage issue behind C1 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes C1 on a GE Appliances Dishwasher? +
Across reported GE Appliances dishwasher repairs, the most frequent is air gap or drain hose partially clogged (40% of cases), garbage disposal knockout plug not removed / disposal blocked (25%), then drain filter restricted (20%). Check them in that order before replacing any parts.
C1 keeps coming back after a reset — what should I check next? +
A reset only clears the stored C1 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the air gap, then check the drain hose and disposal — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix GE Appliances Dishwasher error C1? +
A DIY repair typically runs $0–$100 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
Which GE Appliances Dishwasher models show error C1? +
C1 is documented on GE, GE Profile, and GE Café dishwashers with electronic controls, including touch-UI models like GDT665SSNSS and GDP630PYRFS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
