frigidare dishwasher --- panel or control?

[Wedgeman55]

I have this dishwasher.   Most of the touch pad works but start button doesn't seem to respond.   Put into test mode, and just locks up and will not go through.    Anyone have the manual or any information to help me determine if problem is in touch pad or the computer.?   Thanks.  

Model FDBB1940DB0

Couldn't find a service manual.  Dishwasher was acting real strange.   Went halfway through service test,  stop and lock up.    Cancel drain wouldn't work.  Then, next time it would work.   When it locked up,  6 or 7 of the lights were flashing.   Motor wouldn't run.    I guessed the switch panel,  and was right.      Replaced it and it ran good.   Thing was on this one,   it exhibited symptoms that would lead me to believe it could be either switch panel and main computer. This one was strange,  and I've been doing this for 38 years.  Just letting everyone know in case they run into this model.    Time for a nice cream doughnut and some coffee.
