The door to the dishwasher will not close. There are no obstructions. I've unloaded the washer and tried and it still will not close. I don't know what to do. Can you offer a suggestion?

Close or lock? Many Kenmore's have a thin lockplate that extends into the door frame. Look to see if it is aligned properly and make sure the door isn't hitting the cabinet frame.

Look at it to see why it will not close.
