I entered the dishwasher into service mode and nothing happened. I tested the door latch switch and it appeared to be working correctly. After checking my power connections, and drain, and making sure the other sensors were not sending an error code. I was able to determine the control board was bad, while ordering the board I also ordered a new latch since there are fairly inexpensive. Parts arrived on the day they were supposed to. I replaced the Electronic Control Board and Door Latch with zero issues and the dishwasher was back up and running without any problems.
