Product review (5 stars): easy fix to spraying portable dishwasher connection
SUGGESTION:  also replace the metal adapter that screws onto the end of the faucet that you can buy at any hardware store for under $5.  Surprisingly, the metal ring that those white clips inside the dishwasher collar grab also gets worn down.  In waiting for this item to be shipped, I replaced the faucet adapter and that by itself solved the problem.  Turns out I didn't even need this part.  But $18 for one part in 20 years aint bad.  And better than $100 for a whole new hose assembly.

Fits an almost 20 yr old Kenmore dishwasher even though the model number is not listed in the description, and even though Sears service said I had to buy a entire new collar AND hose assembly.  Since usually only apartment dwellers buy 24" wide portable dishwashers these days, sales are low.  So regardless of the brand, almost are now made by Whirlpool so it's a pretty sure bet this will fit any free standing portable made in last 15 years.

As everyone else says:  5 minute install.  Just lay the old parts on a table in the order you remove them and install the new ones in reverse order.

Item shipped does NOT resemble photo exactly.  The outside collar ring (depicted as the top item in the fuzzy drawing type photo in the description) on the part I received was "chunkier" ,even though the inside diameter was the same.  And seemed to be made of cheaper plastic, or maybe just looked that way because it was shiny.  My old one resembles the one in the photo.  Item shipped was just a more modern version.  Didn't matter as I just used the old one instead of the new one -- can mix & match parts -- old collar ring was just easier to use out of habit.

In the end, unless you've cracked the top collar ring, the only parts you really need are the bottom rubber washer and the 4 white "clips".  And of course a new faucet adapter.
