GE Dishwasher Error Code C2: How to Fix Stuck Buttons
Updated: February 2026
The GE dishwasher error code C2 appears when the control board detects that one or more buttons are continuously pressed or stuck. This prevents normal operation and requires immediate attention.
Common Causes of C2 Error
Sticky residue from spills, worn-out membrane switches, moisture behind the control panel, or physical damage to buttons can all trigger the C2 error. Sometimes detergent splashes or cleaning spray residue is the culprit.
Step-by-Step Repair
- Step 1: Disconnect power to the dishwasher for safety. Don't skip this step when working on electrical controls.
- Step 2: Clean the control panel surface with a damp cloth and mild dish soap. Avoid spraying cleaner directly on the panel.
- Step 3: Use a cotton swab dipped in rubbing alcohol to clean around each button. Work the swab into the gaps to remove sticky residue.
- Step 4: Press each button multiple times to test for sticking. If a button doesn't spring back, it needs deeper cleaning or replacement.
- Step 5: For persistent sticking, remove the control panel cover. This usually involves removing screws from the door's top edge.
- Step 6: Once exposed, clean the membrane switch contacts with electronic contact cleaner. Allow to dry completely.
- Step 7: Inspect for moisture damage or worn contacts. If the membrane switch is damaged, order a replacement control panel overlay.
After cleaning and drying, reassemble the control panel and restore power. Test all buttons to ensure proper function. If the C2 error persists after thorough cleaning, the control board itself may be faulty and require professional replacement.
