Customer Questions and Answers for Dishwasher Control Board by Whirlpool

Hello Ferg, You will want to do a resistance check to make sure that heater is good. You will also want to check connections to make sure no loose or damaged connections. Do a continuity check on the wiring from heater to control board. If all this checks ok then you would replace control board. If heater does not check good then you would replace heater. If there is wiring issue wiring would have to be corrected. Heater should ohm out at 10-30 ohms. 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
