Kenmore dishwasher stuck!!!

I have a Kenmore dishwasher stuck in the wash cycle. My wife started it at approx 7:00 am, before she left for work, and when we got home at 5:30 pm, the machine was still running! None of the buttons will respond and as soon as we shut the door, the wash cycle will resume. It wont drain and cant be canceled. I was just wondering if maybe there was some form of a control panel or circuit board that may be tested. I am sorry but dont have the model #, I have not found it yet. Any insight will be helpful. If you absolutely need some more info, please let me know and I will try to get it, but at this point I am really just looking for some basics. Thank you all so much for your time.:confused:
