Hi Greg,

The first thing I would do is check the chopper assembly (#6 on the diagram). You can find the instructions in one of our previous posts: http://forum.appliancepartspros.com/dishwasher-repair/2903-whirlpool-dishwasher.html

Here are the breakdown diagrams and http://www.appliancepartspros.com/partsearch/model.aspx?diagram_id=130252&&model_id=504341
