Frigidare dishwasher troubleshoot?

My frigidare dishwasher (less than a month old) was working fine until last night. I ran it and went to bed, woke up and it said it was clean. So I went to unload it to find out that it had not run at all. Then I tried to restart it and it wont run. The washer has water and power and all the buttons light up... any suggestions before I take off work and call for a repairman?
