I have the same issue, multiple lights blinking quickly and CANCEL does not have any effect, nor pushing any of the buttons.
I could not locate the Tech Sheet for KUDP02FRSS0, could you share please?
Could you advise me how to determine which part I need to order? I also have not had success trying to reset or put into diagnostic mode. Could you tell me the right sequence and confirm these are down with door open, then when the lights start flashing you close the door.
Very much appreciate any help you can provide.. - Marianne
