Help! Dishwasher won't turn on

My kitchenaid KUDT03STSS2 dishwasher won’t turn on. The lights won’t turn on. It is like it quite in the middle of a cycle. The front panel screws weren’t tight so it was leaking water out. We stopped it, tightened up the front panel screws and then it wouldn’t start back up again.
Thanks in advance for your help!
