Recently my Kenmore dishwasher has become increasingly troublesome. After closing the door, the dishwasher will not start by pressing the "start" button. If I press the "Drain/Cancel" button, it will drain. I can select a wash mode (with the corresponding LED lighting up), I can select a delay start, but pressing "start" does nothing. I took the front cover off and disconnected everything from the main control board. Noticing two bad 470 micro-F capacitors (but not having spares on hand), I put everything back together and turned the power back on. The "Start" button worked properly after that. A few days later it stopped working again, so again I dismantled it, changed nothing, reassembled it and the "Start" button worked again. This process has been going on for nearly a month. A few days ago I bought two 470 micro-F capacitors and replaced the two distended ones. Same result, the start button works and then it doesn't. At this point, I don't know if I should buy a new control board, or a new faceplate (reasoning that the physical button/micro controller is going bad). I found the board to be part number AP3775964 but I can't find the white faceplate. Suggestions are welcome. Which part is likely going bad?
