Whirlpool dishwasher will not start (by 4 users)

Whirlpool dishwasher series DU600 3381181. Now Dishwasher will not start, no lights. There is power to dishwasher connections. Dishwasher did not drain earlier so I pushed drain a few times and I got it to drain, so I ran it on hot cycle and it stopped without draining and not lights. Unhooked drain hose and drained it manually and closed door, nothing happens, no lights, no filling. Any ideas before I call the repairman?
