Kitchenaid won't turn on

This dishwasher has worked fine for the last 5 or so years. I used it two days ago and it ran fine. Today I went to turn it on and none of the lights go on and it won’t start. The main breaker to the machine is fine, the plug in is fine (we checked both). There was no indication of something going wrong. Are there any breakers I should check? Any suggestions on what else we can check before I call the repairman to come in?
