First normal stopped working but we could use auto wash. Then that stopped and also the start button. No lights came on except if I pushed delay then all lights would come on but start would not work. Then all lights would go out after a minute and nothing would work, not even delay. I replaced the electronic control board with a used one guaranteed to work. Same problem occured. I thought maybe the ground was bad so I disconnected and noted that the touch pad responded the same way as when the ground was connected. I reconnected the ground and noted the problem was still there. How do I check for good ground on the board. How do I ohm out the ribbon on the touch pad? Where can I find a good used touch pad?
