Customer Questions and Answers for Dishwasher Water Inlet Valve by Whirlpool

Hello Dave. You will need to test and see if the water valve is getting power at the start of the cycle. If not, then the float switch WP99002560 is bad or the timer 12001533 is bad. If there is power coming to the float switch, but not to the valve, the switch is bad. If there is no power at the float switch, you will need to replace the timer. You can test this with a multi-meter MA-DM1. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
