I researched the issue on line and YouTube had a video that explained the problem with the Bosch dishwasher control board. I checked the manufacturer website and other retail websites to find the right replacement part. AppliancePartsPros.com had the part I needed and could get it to me in the quickest time available.
I used the on-line chat session to confirm the part, price and delivery options. The service associate matched the price I could receive from the manufacturer and the part delivery came 2 days faster than promised (over the New Years holiday).
