Upon inspection, the KitchenAid dishwasher exhibited no lights on its control panel, indicating a potential issue with the user interface control board. I began by disconnecting the dishwasher from the power supply for safety. Next, I accessed the control board by removing the necessary panels and screws. After carefully disconnecting the old control board, I installed the new one, ensuring all connections were secure and properly aligned. I then reassembled the dishwasher, reconnecting it to the power supply. Upon turning the unit on, the control panel displayed the expected lights, confirming the successful replacement of the control board. The dishwasher now functions correctly, with all lights and controls operating as intended.
