If your dishwasher is doing nothing, no lights, no noise, nothing:
I hate to insult your intelligence, but…you’ve checked the breaker, of course, right?
And made sure it’s plugged into the wall?
Here is something you may NOT have thought of…make sure you plug the power cord back into the correct receptacle. Most dishwashers are plugged into a receptacle under the sink…into the same wall outlet as the garbage disposal. The garbage disposal receptacle has a wall switch…if you plug the dishwasher into the wrong receptacle, your dishwasher may not work unless the wall switch is on!
There is one more place to check…the incoming junction box. Power coming from the house is usually routed into this box, and connected to the dishwasher’s wiring using wire nuts. Sometimes they can vibrate loose and wires will short. This will probably trip your breaker…but when you reset it, you will still have no power. The wires inside the junction box are burned.
Though some are hard-wired into the wall, most dishwashers are plugged into a regular outlet beneath the kitchen sink. If you are unlucky enough to have one that’s hard-wired, you must shut off the breaker and disconnect the main power cord at the junction box. This box is usually located just inside the kickplate on the front corner of the machine
