Replaced motherboard/control board

I had to replace the motherboard/control board because the control buttons stopped working, now that everything new is in, the clean light is blinking and beeping. Why is this? I have cut off power to the dishwasher and restarted it. Nothing is working. I installed the new parts exactly how the old ones were. What am I missing?
Please help.

I think it’s the model selector plug but I don’t know how to remove it from the old board and replace it in the new. It didn’t have a cable running to it, it’s just a 3 pronged piece, right?
