After diagnosing and finding the part on your website, I ended up replacing the control board.
I followed instructions from "Drewin' Around" on YouTube at https://youtu.be/SnlGOBVZt1U?si=fqwXsxpkKWMOj916. His dishwasher model was similar to mine and control board was located in the same place.
Removed 5 screws and disconnected 5 wiring harnesses. Easy to replace! I immediately turned the power back on to the dishwasher and started it up.
Thanks for ease of use of your website and giving me the confidence that I was ordering the correct part as it is was discontinued by the manufacturer..
