When I ordered the control board the young lady told me that I had to take the front off the dishwasher. I did exactly as she said and started to put the new control board on. I could not unplug from the old one and finally my son came by and did that. I then put everything back together and turned it on. IT WORKED. Thank you. I should probably tell you that I am a 75 year old woman and if I can do it, anyone can.
