After reading online I decided to attempt installing the control panel. For this particular model, I removed 4 screws at top inside (2 center are longer fyi). There is one more holding the panel in the center, but the front door panel needs to be removed. There are screws all along the inside. Remove those and slide the door panel up and out. Next, remove the last screw and then unplug the wire connector. Replace in reverse order. I did not kill the power to the unit while replacing. It however did not seem to act right to begin with, so I killed the power via the electrical panel for 30 seconds. After that, she was back to her old self. I would advise killing the power just so the mother board gets a clean slate. Glad I tried this. I was about to purchase a new dishwasher. FYI - unit is approx 6 years old and gets daily use. We do clean the dishes off before to remove heavy particles.
