Maytag dishwasher will not start

Mine was doing the same thing and I just pressed and held down the heated dry button until the light went off. Then I was able to start my machine as usual. Hope this works for you.

you'll need to enter a diagnostic mode, press in this order, hi-temp(sani-rinse)----heated dry--hitemp---heated dry... all lights should light, close door and let cycle for about a min, after press the cancelbutton, you should be good to go, the buttons on your model may read slighty different names, if this "toggle of buttons" does not work, you can remove thelower access panel and htere willl be a tech sheet/trouble shoooter behind the panel, in there it will explain how to enter diag/test mode

Hold down the heated-dry button for 3 seconds and the light will clear.

I was able to reset it using this procedure:

1. Crack the dook open

2. Within 3 seconds, press these buttons in this squence: Hi Temp Wash, Heated dry, Hi Temp Wash, Heated Dry

3. Close door

4. Press Cancel

That should clear the Blinking LED. It appears this is a common problem. The worst thing is they charge to come out for this.

The "3" means hold for 3 seconds to child proof it. When it's on, none of the functions work. When you hold it again for 3 seconds, it turns off and your buttons will work again.
Good luck!
