Frigidaire not turning on

Our Frigidaire dishwasher is not turning on. The door closes and latches (I just replaced the latch in case that was the problem) and the digital display reads 93 min but does not say "lock" which is what it has said in the past. Because of that I replaced the latch but it didn’t help. The buttons on the left side appear to work and you can select which cycle you want but the start button (on the right side) does nothing. Thanks!
