We have a Kenmore mod# 13743k. When I touch any wash mode the light comes on normally - but when I hit "start" it does nothing. It had been operating fine prior.

SOURCE: Lights flash but wont start

If the dishwasher is still under warranty, best thing will be to conntact for manufacturer service !! The problem you describe could be cause off : * A Defective switch level that doesn't "shows" that there is enough water in the dishwather and therefore will prevent program's advance. * A defective heater- If water will not reach need temperature it will prevent program's advance as well. * Defective timer - Dishwasher's heart. In case your washer is over its warranty period and you would like to solve your problem by yourself, let me know and I will instruct you step by step how to to find the defective part and how to fix it. Good luck !

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this.

I suspect for either of these units that the timer control boards are bad.
