Mark D for Model Number LDF6810BB Went to turn the dishwasher on it has no power at all . Even the Led lights on the buttons are dead. Called LG they said there guess was it was main computer board. I really don't know how to check a computer board to see if it is bad. I am willing to take a guess at it before I call for help . Where would you check first or what part would be your guess as to why it is complete dead ?
Answer Hello Mark. It is best to test for power to the main board. If there is power there, replace the board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
