Hi, I have a sears Ultra Wash II 665, I have 2 problems, it is cleaning but leaves a residue on the classes, I did check the filter and is ok, also put in the vinegar..didnt help.

Next problem is that the desenser for the spot free liquid is always full. could it be plugged up. I do not see where it would come out...any help would be appreciated...thanks
