My dishwasher has no power. I have checked power at outlet and it is good. I am told that my control board is bad. How do I verify that is the problem. If it is how do I change it out?
Answer Hello Gerry,
You would want to test to make sure that the control board is getting power between L1 and neutral on the control board using a voltometer. You should have 120 vac to the control board. To access control board you would remove the screws on the inner panel of the dishwasher. 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
