Dishwasher hums but doesn't fill

When you push the start button, the dishwasher lights go on. The dishwasher sounds like it’s starting but after about 20 seconds the clean light comes on. I have found that if I wait maybe 15 seconds after pushing the start button and then open and close the door, the dishwasher cycles normally. Usually when I open the door I hear a hissing sound like a dry pump is running. And the other thing that is strange…once in a while it runs normal without my having to open the door. What’s going on here?
