GE Cafe Dishwasher wont start

I have a GE Cafe dishwasher model CDW9380N20SS
The dishwasher will not start, I have tested the door latch with my ohm meter and it appears to working, I replaced the touch pad but still nothing is working. The start light on the key pad is illuminated and the normal wash light is illuminated but machine does not start. Otherwise the other key pads functions do not work. Is it possible the module controller is bad? and how can I test that? I don’t want to purchase a new control module unless I know for sure it is bad due to the cost of this part!
