Error codeC1
ApplianceDishwasher
What C1 is reporting
The dishwasher timed the pump-out during its drain phase, and it passed the 2-minute mark. GE adds that no single model displays every code, so confirm what your own display reads.
Three fixes, one after another
Give the air gap a thorough cleaning.
Swap in a new drain hose, or reposition the one you have.
Run the garbage disposer so it is cleared out.
Contact service if C1 is still there afterward.
Drain codes that look alike
C2: the full pump-out cycle goes beyond 7 minutes.
When the code survives the air gap, hose and disposer work, call (415) 729-2045 to book GE dishwasher repair in San Francisco and the Bay Area. Tell us it is C1, give the model number, and list which of the three steps you finished.
Model compatibility: GE reuses codes across series and model years, so C1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The pump-out during the drain phase lasted more than 2 minutes.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
