Confused Dishwasher

My dishwasher gets very confused. It no longer will start a regular cycle wash (this has been true for 2 years) but now all the other wash cycles alway show as a delayed start but are actually washing. But the cycle never finishes, it counts down to 1 minute and stays there. sometimes it does open the soap either.

I suspect the control module. are there other possibilites and how would I test that. If it the control module, do you have installation instructions.
let me know thanks

sound like control module. outer door +control panel have to be removed with torque screwdriver
