The C2 error code means the dishwasher attempted to drain but the drain cycle exceeded the maximum allowed time without the control board confirming the tub was empty. The fault indicates a slow or blocked drain that prevents water from evacuating within the expected window.

Answer to continue safely
Is it safe to keep using?
Maybe. The dishwasher is safe to inspect but should not be run through another full cycle until the drain obstruction is cleared. Running repeated cycles with poor drainage accelerates pump motor wear.
Can I reset the code?
Yes. Press the cancel/drain button to attempt a forced drain, or cut power for 60 seconds. If the underlying obstruction is cleared, the reset will hold and the unit will resume normal operation.
When to stop immediately?
Stop if you notice: Stop running cycles if water consistently remains in the tub after every attempt, as this accelerates pump wear and promotes mold growth., Stop if the pump makes a grinding or screeching noise during the drain phase, which may indicate a seized impeller..
Symptoms You May Notice
Standing water remains in the tub after the cycle
Opening the door at the end of a cycle reveals an inch or more of standing water sitting in the bottom of the tub instead of an empty, dry interior.
C2 shown on the display
The control panel displays the C2 fault code and the cycle halts or pauses during the drain portion of the program.
Drain pump runs but water does not recede
You can hear the drain pump motor humming or buzzing, yet the water level inside the tub stays the same or drops very slowly.
Unpleasant odor from standing water
Food particles and dirty water left sitting in the tub quickly develop a foul smell, making the odor noticeable when the door is opened.
Possible Causes
Clogged filter or drain basket
The cylindrical filter assembly at the bottom of the tub collects food debris. A heavily clogged filter severely restricts water flow to the drain pump, causing slow or failed draining.
DIY PossibleBlocked or kinked drain hose
The corrugated drain hose running from the pump to the sink drain or garbage disposal may be kinked behind the unit or blocked by a grease or debris buildup.
DIY PossibleFaulty drain pump motor
If the impeller inside the drain pump is broken or the pump motor has failed, it cannot generate enough pressure to evacuate the tub within the allotted drain time.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the filter assembly
Twist and lift the cylindrical filter from the tub floor. Rinse it under running warm water and use a soft brush to scrub away any trapped food particles or grease.
GE recommends cleaning the filter monthly for best performance. Reassemble by aligning the arrows and twisting clockwise until it locks.

2
Check the garbage disposal knockout plug
If the drain hose connects to a garbage disposal, verify the knockout plug inside the disposal inlet was removed during installation. A missed knockout plug fully blocks drainage.
Run the garbage disposal for 15 seconds before starting a dishwasher cycle to ensure the inlet is clear.
-
3
Inspect the drain hose for kinks
Carefully pull the dishwasher forward slightly or peer behind the toe-kick to trace the drain hose path. Straighten any visible kinks and confirm the hose forms a high loop under the counter before connecting to the drain.
The high loop (or air gap) prevents backflow from the sink from entering the tub.
Tools required
When to Call a Professional
Contact a qualified technician if:
- The filter is clean, the drain hose is clear, and the garbage disposal inlet is open, yet the C2 fault persists.
- The drain pump is audibly running but producing no water movement, suggesting a failed impeller or pump motor.
