GE Dishwasher C2 Error Code — What It Means
The C2 error code on a GE dishwasher indicates that the total pump-out cycle exceeded 7 minutes. GE classifies this as a drain or pump-out fault. The dishwasher is unable to evacuate water from the tub within the expected time, so the control halts the cycle and throws the code. In most cases, the problem is a restriction somewhere in the drain path that slows or blocks water from leaving the machine, though a weak or obstructed drain pump can also trigger the fault.
Common Causes
- Blocked or kinked drain hose A clog, kink, or improper routing in the drain hose restricts flow and prevents the dishwasher from pumping out water in the allowed time.
- Clogged air gap If your installation includes an air gap at the countertop, food debris or buildup inside can block the drain path.
- Garbage disposer knockout plug left in place When the dishwasher drains into a disposer, a knockout plug must be removed from the disposer inlet, or water cannot exit the drain hose.
- Dirty filter or sump debris Food particles and grease in the dishwasher’s internal filter or sump area can restrict the pump and slow down water removal.
- Weak or jammed drain pump The drain pump itself may be obstructed by debris, mechanically worn, or electrically failing, preventing it from moving water efficiently.
- Control board or wiring fault If the drain path is clear and the pump is good, a problem in the wiring harness or control board output may prevent the pump from running properly.
Step-by-Step Fix
- Reset the dishwasher by pressing the RESET button or turning off power at the circuit breaker for at least 30 seconds, then restore power and see if the error clears.
- Check the air gap (if installed) by removing the chrome cap at the countertop and cleaning out any debris or buildup that could block the vent.
- Inspect the garbage disposer connection under the sink and confirm the knockout plug has been removed from the disposer inlet where the dishwasher drain hose connects.
- Examine the drain hose for kinks, clogs, or sags that could trap water, and verify it is routed with a high loop or air gap as required by your installation manual.
- Remove and clean the dishwasher filter at the bottom of the tub, and check the sump area beneath it for any food particles, glass, or other debris.
- Run a test cycle and listen to confirm the drain pump runs continuously and strongly during pump-out, and watch that water actually drains from the tub.
- If the code persists after clearing all obstructions, contact a qualified service technician to test the drain pump assembly, wiring harness, and control board output before replacing parts.
Parts Often Needed
| Part | Notes |
|---|---|
| GE dishwasher drain pump assembly | Amazon | Replace if the pump is mechanically jammed, electrically failed, or unable to move water after obstructions are cleared. |
| Dishwasher drain hose | Amazon | Use if the original hose is kinked, cracked, or permanently clogged and cannot be cleared. |
| Dishwasher filter and sump components | Amazon | Order if the internal filter is damaged or the sump housing is cracked and allows debris to bypass into the pump. |
When to Call a Pro
Call a professional if you have cleared the drain hose, air gap, disposer connection, and internal filter but the C2 code returns on the next cycle. A technician can perform electrical tests on the drain pump, verify control board output, and trace wiring faults that are not visible during a basic inspection. Also call for service if you are uncomfortable working under the sink, disconnecting the dishwasher, or removing internal components. GE advises contacting service when the fault persists after basic troubleshooting.
