Like its getting air in it. It has plenty water in it but while its washing i just hear something. Is there a check valve anywhere that can go bad and cause this. It isnt over sudsing either.

Are you using a detergent that causes foam? Cascade is notorious for this. Finish used to be.

The post KD-20 Hobart dishwashers had a check valve that can go bad which kills washing performance. Not sure if this is a Powerclean design or not. Here's a thread about the check valve.
