Hi @pattig68389
Try performing the ''Water/Service test (WST)'' as described in the [document|39386|service data sheet] and check if this resets the dishwasher.
If still no good, then if checking the control panel keys or cleaning the control board cable connections as suggested above doesn't work also visually inspect the control board for any obvious signs of component damage i.e. burnt out or heat stressed components on the board.
If there is evidence of component damage on the control board and you're not sure (or even if there isn't) post a few close up images of the board in your question on ifixit to get more help. Here's how to do this on ifixit [guide|21499]
If you want to try replacing the control board to see if that resolves the problem search online for either [https://www.google.com/search?client=firefox-b-d&q=5304502611|5304502611]¹ or [https://www.google.com/search?client=firefox-b-d&q=5304512731|5304512731]¹ to find suppliers that suit you best.
¹ Supplier examples only to show possible cost of board. The first number linked is the Frigidaire part number for the original board used in the dishwasher (it should be printed on the board somewhere if you wish to confirm). The 2nd number is the part number for the board that has superseded the original board as it is not made anymore by the manufacturer. This doesn't mean however the the original is no longer available, maybe just that it is harder to find that's all.
