Just bought a house with this dishwasher installed. It seemed to get stuck on the wash cycle for over an hour. I ended up having to push the cancel button.
Any suggestions for why this may have occurred or what I should do? It's not an old model!! Help!

Look at these manuals and see what you can find out: http://dl.dropbox.com/u/8010163/Dishwasher%20Service%20Manuals-Whirlpool-Kenmore.zip
You will probably need a good digital meter to diagnose it.
