Kennmore ss dishwasher model # 665.16462300 purchased in 03, replaced control panel 9/07 under warranty. Now it quit working again. The "delay hours, cancel/drain, and start" buttons do not light up or anything. The other buttons under "cycles & options" light up red when pushed, but nothing happens. Iv'e tried disconnecting power, resetting & pushing all the different buttons that I've been reading about, nothing changes. Is it possible this could be another control panel failure?
