Tip & How-To about Dishwashers
If you have a dishwasher that is not doing anything, the first thing to check is the incoming power. Make sure the circuit breaker is on and not tripped.
Another place to loose power to the dishwasher is under the sink if it is plugged in to an outlet. It could have come disconnected.
The third place to look is a wall switch. If you have a switch that does not operate a light in the kitchen it may be connected to the dishwasher power source.
If all of these are okay the next place to check is the junction box of the dishwasher. To check here you will want to turn the breaker off first or remove power from the cord before taking panels off. By removing the kick plate or lower panel on the dishwasher you can access the electrical junction box. Many times the wire connectors were not properly installed in this box and over a period of time the connection is lost. This connection should be made by a professional.
If we have power to the dishwasher a common component to fail on many brand such as Whirlpool, KitchenAid, Kenmore, Maytag is the thermal fuse. This device is a two wire heat activated fuse that if tripped will disable the dishwasher. This thermal fuse is attached to the control circuit board that is usually in the console in the upper portion of the door. It can be checked with an ohmmeter just like a regular fuse. When replacing this fuse it may come as a kit with wire connectors, be sure to use all of the parts in the kit. The fuse often will blow due to a loose wire connection on or near the fuse, that is why new connectors are supplied.
A sample image of a typical thermal fuse kit is shown below.
