Why won't my new Kenmore 22-15259 dishwasher completing a cycle?

We got a new Kenmore Dishwasher 22-15259 about two years ago. It was not taken out of the box until this weekend when we finally installed it. We ran it thru a quick rinse cycle and before it was done it shut of and the hi temp and heat dry lights starting blinking and there is 2 inches of water in the bottom. I got it to drain by hitting cancel twice. I then tried to run it thru a normal wash cycle and it did the same thing. Only it shut off before it dispensed the soap. What should we do? This is brand new but its out of warranty because it sat in the box for 2 years.
