Product review (5 stars): Dishwasher rinse cap
I had the same results as other reviewers. I spent $1500 for a new Kitchen Aide dishwasher and the cap was missing. After using up 3 bottles of rinse in 3 months, I checked the manual and lo and behold there should be a cap over the fill area. I called KA and after holding for 1/2 hour they said I had to replace the entire assembly. I said all I wanted was a cap (50Cents) that should  have come with the dishwsher, 3 months old and under warrantee. The "Customer Support person" said he was sorry but I had to spend $40.00 and buy the entire assembly. Well, you know I blew a fuse by this time and said a few things I cannot repeat. Went out on the net and had to pay $17.00 for a cap plus $7.50 Fed EX shipping. Only in America!!! I think I will tie a chain around this new one.
