Reviews

It fits!
July 05, 2023

With a little modification and thought I managed to get the part to replace the old (23 years!?) manifold. It was not perfect but I did make it work to my satisfaction. Sure beats getting a new dishwasher!

You Changed my Part
June 21, 2023

Instead of replacing 1 part, you replaced 3 in 1. However, you didn't send me the specialized screwdriver to install it! Besides that, when I tried to order online, I received a server error two times.

Worked well

Easy to install, required me to make a modification to bracket at rear of unit, unable to fit new one piece assembly through bracket. The old Assembly was three separate pieces.

Functions but...
January 07, 2021

Works now...but I had to grind out a spacing tube where the part screws onto dishwasher. The original part didn't have that spacer so I couldn't get the new part on until it was removed. I used the part number provided in the manual, so Sears apparently has modified the original part or they gave me the wrong part number. At least it works now.

It works
December 03, 2020

The only problem was the plastic bracket that holds it up was not big enough to go over the new arm piece. We had to break it so this arm could fit in. So far though, it is still working. We broke it on top so the pressure would push down away from the break on the bracket.

Required modification, was not an exact fit
November 16, 2020

This was not an exact fit. The original part on my Whirlpool GU940SCGZ2 did not have the inner spindle/sheath that this new part does and the spinning spray part had a larger spine than would fit in this. I was able to modify the spinning spray by cutting down the spindle on it and it seems to work fine. I considered returning it but decided it would be simpler to try the modification and if it failed to buy the upper sprayer. The old part was 3 pieces with a rotted rubber tube. Dishwasher seems to a bit better than before.
