Dishwasher no power at panel door won’t latch

This is a Frigidaire dishwasher that was only 3 months old and suddenly stopped working with no indicator of power or lights on the control panel. After resetting the breaker and attempting several “resets” using the recommended button combinations, I discovered the actual problem was the latch mechanism being in the locked/closed position even when the door was open. Follow this procedure to get the latch back on track and hopefully take care of your problem as well.
