KitchenAid Dishwasher

My dishwasher is acting like it is not getting power. It is direct wired to the electrical. I am wondering if it could be a fuse issue, a timer issue, or circuit board? I have checked the electrical feed and all is well. So - I am left with decifering the timer verses the circuit board. Any suggestions???

Check the thermal fuse (#22 on the break down diagram) and the door switches.

Here are the break down diagrams for the Kitchen Aid dishwasher Model KUDI24SEBL4

P.S. There is no a timer in this dishwasher.
