Troubleshooting Steps:

  1. Check Touchpad and LED Assembly:

    • Select different wash cycles, change modifiers, and adjust options to test if the touchpad/LED assembly responds appropriately.
    • If unresponsive or erratic behavior is observed, it indicates an issue with these components.

  3. Inspect Wire Harness Connections:
