You might try reading the "Canceling or Changing a Cycle" instructions in your manual. My dishwasher was stuck in the drain cycle, and it would never start washing. The diagrams in my manual did not match my dishwasher, but I did figure out that if I pressed the "Power Scrub" button and the "Regular" wash button at the same time, it cancelled the drain cycle and allowed me to start the dishwasher again and it now works fine. I suspect that your machine will have a similar solution.
