Update
The dishwasher finally died again in 2016. The uninterrupted power supply that I purchased for it wasn't large enough so it died again.
I called a serviceman to look at it and as soon as he left, I found both the main control board for $150 on ebay and the controller for $30. It was a new and unused controller as another serviceman ordered it a long time ago, never used it and decided to sell it on ebay in 2017! Remember, this is a 1988 Kitchenaide Dishwasher. Finding these two parts was unbelievable luck and timing.
The serviceman came back and installed both parts and, I am happy to say, it is now working. I am leaving it unplugged til I use it as any power surge might kill it again.
So I have about $500 in it to get it going again incl service calls. Worth it to me because it had little hours on it and it is made so well.
