GE Dishwasher Error Code C3: Door Latch and Switch Repair

Updated: February 2026

When your GE dishwasher displays error C3 , it's alerting you to a door latch or door switch malfunction. The dishwasher won't start because it can't verify the door is securely closed.

Understanding the C3 Error

💡 Pro Tip: Take a photo of this guide on your phone so you have it handy when you need it most.

The door latch assembly includes a mechanical latch and an electrical switch that signals the control board when the door is closed. The C3 error means either the latch isn't engaging properly or the switch isn't registering the closed position.

Complete Troubleshooting Process

  • Step 1: Inspect the door latch striker on the door for damage, misalignment, or buildup of debris. Clean or adjust as needed.
  • Step 2: Open the door and examine the latch assembly on the dishwasher frame. Test the latch mechanism by pushing the striker portion to see if it engages smoothly.
  • Step 3: Remove the inner door panel to access the latch assembly. This requires removing screws around the door edge.
  • Step 4: Disconnect the wires from the door switch and test with a multimeter set to continuity. The switch should show continuity when manually activated.
  • Step 5: If the switch is faulty, order a replacement door latch assembly for your GE model.
  • Step 6: Install the new latch by reversing the removal process. Ensure all wire connections are secure.
  • Step 7: Test door closure multiple times before fully reassembling to confirm proper engagement.

Sometimes realigning the door solves C3 errors without parts replacement. Check that the door closes evenly and the latch aligns with the striker. Adjust mounting screws if necessary to achieve proper alignment.

Bottom Line: GE Dishwasher Error Code C3: Door Latch and Switch Repair does not have to be complicated. Follow the step-by-step approach outlined above and you will be set for success.
