Dishwasher Not Working

Dihwasher Quit In Cycle That Left Water In Bottom Of Unit. I Cannot Get It Do Anything. I Checked The Plug In, And Checked The Door Of The Dishwasher. Everything Looks Fine. MODEL # 66517829000

Note: A Month Ago I Replaced The Hoses From The Washer To The Water Supply Spigot. The Dishwasher Was Used Many Times Without Any Problem.
