Product review (5 stars): Excellent Price Saved $$$
All i needed was the detergent gasket but those are not sold separate from the dispenser unit.  My local repair shop had quoted $65 plus the same amount for labor to install.
Being a penny-pincher, I looked up the part number for my Whirlpool Gold dishwasher online  & did comparison shopping. I was very happy to find the identical product on Amazon at a much lower price. I decided to try the install myself & was able to install it in way less than half an hour!  All in all I saved close to a hundred dollars and that made me ecstatic!
**you'll find this is what Whirlpool terms a "comparable" part, ie it isn't exactly 100% identical to the the original part. If you attempt the install yourself the only thing you'll find different is the wire connection on the rinse-aid compartment side. The original has a slot into which the wired card fits tightly & the slot on the new part is larger & the card would not stay.  I simply anchored the piece securely near the appropriate location & everything worked for me like a charm!
