Product review (5 stars): Worked perfectly in my Whirlpool Quiet Partner II (model DU1345XTVB0)
We recently bought a house with a Whirlpool Quiet Partner II (model DU1345XTVB0) dishwasher, and the rinse dispenser didn't work. It stayed filled with water and/or leaked out the rinse aid and was simply not usable.

I found this on Amazon and it appeared to be the correct part, but it's sometimes hard to tell so I was holding my breath, but it was an exact factory replacement of the existing part.

Installation was not overly complex, you have to remove the hex-drive screws from the *inside* edges of the door that hold the colored panel to the *outside* of the door, making sure not to remove the similar screws from the top of the door that hold the control panel in place. Once you remove the screws the colored panel will drop off, revealing the back side of this dispenser.

The dispenser is held in place with very small hex nuts, and I actually had to run to Lowes to get a socket driver small enough. You have to remove the screws, unhook the wire, save the protective flap of plastic (it hangs down over the dispenser to protect from wayward splashes) and metal retaining frame, remove the old dispenser, insert the new dispenser, hook up the wire, put the retaining frame in place (holding the protective flap), and reinsert the screws.

Overall it took about 20 minutes to complete. If I had to do it again it would take 5-10 minutes tops, as it is actually pretty simple once you get the layout of things.

With the new dispenser in place things are working great. Before this fix we had stooped to using the little hanging baskets of rinse aid, but those impart a particular (overpowering) smell and also tend to leave a dust-like residue on some metal dishes/utensils. However, we're now rinsing clean and clear.
