Product review (5 stars): great!
My dispenser cap fell out during a cycle and melted, so the rinse agent kept draining after one load. I went to sears.com to look for a cap and they were like $25.00! The price was outrageous for such a small piece of plastic! I was very nervous about if this would fit my dishwasher since it is a Kenmore, but it turns out that whirlpool makes kenmores. I  bought this one based off of looks, and it fits and functions completely perfectly! So if your not sure if it will fit or not, my advice is if it looks like your current cap it most likely will fit.
