Starts cycle, gets "stuck" with h2o in bottom, timer is still heard-lights on too.

Hi. This is the 3rd time. Last 2 times I simply restarted the cycle and it was fine. This time, however, the water is standing (as it was the last 2 times)in the bottom, the normal wash light is on, I can hear the timer (sounds like a timer) running in the control panel, I tried resetting it and the same disfunction occurs. We bought the house 2 years ago, it is a 9 year old house. We do not have owners manuals or anything. I felt around in the water to see if something was blocking it-nothing. We do rinse the dishes thoroughly. I need trouble shooting ASAP, PLEASE!!! We are able to do -do it yourself- at home repairs. Thank You. Sincerely, John & Julia
