This has happened on both of our Maytag dishwashers. One bought in 1998ish and the other in the new house. Both failed on the very first load or one there after.
Both required new controllers. Thankfully they were under warranty. Took about a week to get the parts.
Two Maytag washers. Two warranty repairs.
One Maytag fridge. One warranty repair.
The Maytag stove and microwave have been fine....
Is there a pattern?
The dishwashers have run fine after the defective controllers were replaced.
Later,
Dan
