After a wash cycle, I still have soap in the washer. I have to run several
rinses or a couple washs with no detergent to get rid of it. I am using
extremely little detergent. Much less then what is called for.

So far I checked the screens in the hose lines to see if they were clogged.
They were clean. I ran some powdered Cascade thru the washer. I was told
this trick removes the detergent build-up inside. It didn't help. The
service man want about $80 just to look at it.

Has anyone ever had this problem or does anyone know what is actually
causing this so I can attempt to fix it myself?
