Never gets to Dry Cycle...?

This dishwasher is 5 yrs old- works great up to now. Will run entire cycle, then just before dry cycle starts, the panel blinks, then beeps and then cycle ends without drying.
I used the debug/test mode to turn on the heating elements, and they work fine. This tells me the controller and the heating elements are working, can something be going wrong between the rinse and the dry cycle?

Any suggestions for me to check?

Thanks in advance!

Sounds like the control board has gone bad.

  • The part number for the control board is AP3203951
