GE Dishwasher Error Code Start LED

The Start LED error indicates a communications failure between the user interface control board and the machine control board. The two boards are not exchanging data as expected, so the dishwasher cannot operate. This is most often caused by a loose wire harness connection or a failed UI board.

No. When the Start LED communications failure is present, the dishwasher cannot complete a cycle because the UI board and machine control board are not communicating. Attempting to run the unit in this state will not produce results and will not cause additional damage, but the dishwasher will not function until the underlying issue is resolved.

A reset may temporarily clear the error, but if there is a physical wiring or board problem, the Start LED will return once the dishwasher tries to communicate again. To reset, disconnect power for 60 seconds and restore it. If the error comes back immediately or on the next cycle, move on to inspecting the harness connectors and testing the UI board.

Start by unplugging the dishwasher and inspecting the wiring harness connectors between the UI board (inside the door panel) and the machine control board. Reseat any loose connectors and look for corroded or bent pins. If the connections are secure and clean, the UI board is the most likely cause and should be replaced. If a new UI board does not clear the error, the machine control board may need replacement.

If the fix is simply reseating a loose connector, there is no parts cost. A replacement UI board for a GE dishwasher typically costs between $80 and $200 depending on the model. A machine control board runs $100 to $300. If you hire a technician, add $100 to $200 for labor. DIY replacement of the UI board is manageable for most homeowners since it involves removing the inner door panel and swapping the board.
