What Does Error Code C2 Mean on a GE Appliances Dishwasher?

Drain failure — total pump-out cycle exceeded ~7 minutes.

The control board monitors the drain phase and expects standing water to clear within a set window. When the drain pump runs cumulatively past its maximum pump-out time (about 7 minutes) and the sensor still detects water in the tub, the board halts the cycle and flags C2. Unlike C1, which signals a slower or partial drain, C2 represents a full failure to evacuate water, pointing to a hard blockage in the drain path or a non-functioning pump.

Models affected: GE dishwashers using the C-series fault codes, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS
What owners report: Owners commonly report C2 appearing at the end of a wash with standing water left in the tub, often after a new install where the disposal knockout plug was never removed or the drain hose is kinked. A frequent quick win is clearing the filter and sump or freeing the air gap, after which a Rinse cycle drains normally.

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error C2 appears? +
It is not advisable. The dishwasher may still power on, but running it while C2 is active can worsen the drainage fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes C2 on a GE Appliances Dishwasher? +
Across reported GE Appliances dishwasher repairs, the most frequent is drain hose or air gap clogged (35% of cases), drain filter or sump blocked (30%), then disposal blocked / knockout plug in place (20%). Check them in that order before replacing any parts.
C2 keeps coming back after a reset — what should I check next? +
A reset only clears the stored C2 fault; if it returns, the drainage problem is still present. Move on to the physical checks — press RESET to stop the alarm, then clear hose, air gap, 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 C2? +
A DIY repair typically runs $0–$120 in parts, versus $150–$300 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 C2? +
C2 is documented on GE dishwashers using the C-series fault codes, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
