GE Dishwasher Error Code C2

C2 means the dishwasher's drain pump ran for more than 400 seconds without successfully emptying the tub. When this threshold is reached, the control stops the pump for 5 seconds, then restarts it while energizing the drain solenoid to determine whether the drain valve is stuck or the drain path is physically blocked. It points to a restriction or component failure somewhere in the drain system.

A reset may clear the code temporarily, but the fault will return if the underlying cause is not addressed. Because C2 is triggered by an actual timed drain failure rather than a sensor glitch, the drain system blockage or component problem must be corrected for the code to stay cleared. Always diagnose and fix the root cause before relying on a reset.

If the fix involves only cleaning the filter, air gap, or disposer connection, there is no parts cost and the repair is a DIY task. Replacing a drain solenoid typically runs between $20 and $60 for the part, while a pump motor mechanism can range from $50 to $150 or more depending on the model. Adding professional labor generally brings the total repair cost to somewhere between $100 and $300 for component replacements.

Start by cleaning the air gap at the sink and running the garbage disposer to clear any blockage at the drain connection. Next, remove the filter screen inside the dishwasher tub and clean the filter chamber, checking the check valve gasket for swelling. If those steps do not resolve the fault, the drain solenoid or pump motor mechanism may need to be tested and replaced.

Running the dishwasher with an active C2 fault is not recommended. If the drain is blocked or the pump is struggling, standing water can remain in the tub between cycles, which creates sanitation concerns and puts additional strain on the pump motor. Resolve the drainage issue before running additional wash cycles.
