Kenmore Elite Dishwasher 665.17462300 control panel is stuck. The "Normal Wash" and the "Cancel Drain" light are on continuously, with no blinking. I have disconnected power, checked power, removed control panel cover, reseated the ribbon cable connector, checked control board for burns, all result in nothing. Is there something that I don't know about this problem? Serial number is FR0807392. Thanks!
