Kenmore Elite Dishwasher?

I figure there is someone out there that can help me with this. I am desperate as Sears can't come out for 1 week and I don't have a Warranty on it. I am a fix it person so I figure I can do this. My Kenmore Elite Dishwasher no. 665 13793K601 that my wife bought new (well 1 year old but still in box off Craigs list clean light is flashing. It seemed to be cleaning dishes the first time with the 3 lights coming on in order of cleaning but then the Clean button now is blinking green and nothing will happen. Manual says call for service? Can I reset it, push in a code to fix it? thanks.
