Kitchenaid 2 lights blinking won't start

Normal and Rinse Only lights blinking. Disconnected and reconnected ribbon cable, and cycle started fine. After a few minutes, pressed cancel/drain which also worked. Maybe I shouldn’t have canceled it as now Normal light blinks and won’t start. When you press start, the rinse only LED starts blinking too. Seems a little like waverider’s post. I guess I have to find teeny tiny probes to test the cable? Btw, this happened 3 months ago and disconnecting cable worked until now. Any help greatly appreciated, don’t want to buy a new one. Thanks!
