We have a Kenmore Elite 665.13124K703 that suddenly stopped doing anything but Cancel drain. No other control LEDs will light. The time delay lights for 1,2,3 hours (or what ever it is) does also light. All other buttons seem totally unresponsive. I cannot run any diagnostics. After looking everything over it seemed like it could only be the control board so I got a new one from here but does exactly the same thing. All connections look good. The drain motor works but nothing else. Is there some sensor somewhere that will shut down everything but cancel/drain?
