I am presuming that the problem is within the electronics, but which part is most likely defective, Electronic Control Assy. P/N 9743448 or Switch, Panel P/N 9743242?

Suddenly quit doing any wash cycles. When attempting to start any cycle, now will only exhibit green "clean" led lamp and red "cancel" led lamp, both at the same time. I can hear the motor running for a short time before this happens, but there is no normal activity.

Unit completed a successful wash and drain yesterday with no problem.

This same problem occurred 4-5 years ago and ended up with the serviceman making three trips and $400+. I know he replaced one of those modules, but I don't know which one.

Knowing a little bit about computers, I'm willing to tackle this one myself because it is a quality unit and I don't look forward to replacing the dishwasher, even if it is an older model.

Thanks for any insight or recommendation on which part (or both) that I should order. Perhaps I should order both, install the most likely, and return the other one if the first one works, huh?

Thanks, but continuity otherwise appears OK. Anyone have experience with these particular circuit boards?
