My dishwasher will not start: Most common d/w power is 120 volts, check for 120 volts with a volt meter at the main power harness where it enters into the dishwasher, you will have to remove the lower access panels to get to the power box. Dishwashers also have at least one and most newer dishwashers have two door switches that must be checked. You will find then behind the console at the door latch area. Each manufacture has different designs but this is a picture of what some of the newer dishwasher switches look like.
