Hello all, I am thinking about converting my dishwashers system to the more I suppose basic tower powerclean/ultrawash design. Not for a permanent change, but just to see how it works. I know I need the tower, upper arm, spray arm rubber black cap for the upper feed, & finally the pump outlet.

I do know they made a few different version pump outlets for different model years, so if anyone knows would this pump outlet fit my dishwasher on this ebay listing if I were to convert it? Just want to make sure my arm with the plastic cover plate and all will fit correctly. Photos of my machine will be below, just the most recent version of the powerclean, 5 level.

Also here's a link to the Service manual...the models listed in it are a little older but it is the same module as what is in yours.

Thank you....

I already have the seal and the one in the ebay listing is the same exact one, same part number. So I will order. But I cannot find a upper spray arm anywhere for purchase but I remembered GE sold a version for a while that was similar to the powerclean tower style, would this arm work do you think instead of finding a Whirlpool model one? It snaps onto the rack and has the funnel at the bottom as you can see.

The part number is 8268829. This really will turn into a Frankenpool lol. I would probably be more worried about mounting it to the rack, there probably are differences there. Also worth noting that the whirlpool arm had a self centering funnel to catch the full force of the stream of water, and that the PC probably moves a lot more water than the GE pump did. I'm sure if you keep digging one will show up.

Thought it may took longer...

But I did find the actual spray arm with the correct model number, bought from certified parts online. In which it’s the color I wanted to match, so all the parts are currently on order for what I need to make this conversion happen! Thanks much for the provided information here, I’m excited to see how this works as I do have a camera I can use inside the machine as long as it’s contained dry by a jar & clear plastic ziplock. So stay tuned for the results!

Having owned and used both style machines, I cannot begin to imagine why you would want the wash tower in the lower rack! You get the same, if not better performance with the feed tube system, and no lost space in the lower rack.

Because I think it’s more interesting, just something I’ve always wanted. And since the machine I have is convertible why not do it, i can switch back at anytime. I love the 5 level powerclean which it already is, but I’ve always wanted the tower system.

WP PC DW Tower Wash System Vs Rear Feed

combo52's profile picture

The tower wash feed was a perfect design for function and simplicity. 

 

It worked at least as well as the rear feed tub and did not suffer the failures of the rear feed system, Including 

 

Top  wash arm bearing failures, 

 

Dislodged support hanger that interfered with arm rotation.

 

Both are great systems, but I will never switch to the rear feed on our 2 WP PC DWs, when I want to wash something huge in the lower rack I just remove the lower rack feed tube.

There are so many items I try to load in the bottom rack, and when I go to roll the lower rack back in whatever’s I may have like plates or a lid ect will hit the feed supply on the back wall where it connects to the upper rack and it’s just honestly so annoying, I’ve been dealing with that for years because my Maytag at my other house has the same upper wash arm as my 2001 5 level accuwash with the feed tube, the tower style as Combo said doesn’t clean any worse. The only thing I’ll be missing is the roof shower spray, which isn’t a big deal to me because at any point I’ll have the parts to switch it back over to the feed supply system.

Parts are on they’re way, finding a upper spray arm in grayish white was extremely hard. Nobody had them in stock, even on eBay. There was one for sale on eBay but it was missing the the clips that hold the arm onto the rack. But finally I did find one that’s used for sale so it’s on the way, plus the correct pump outlet, tower for the rack, and black rubber cap for the lower arm. I’ve always been intrigued by the 3 level powerclean design, so that’s why I’m converting over to it as I just think it’s way more interesting than the direct feed 5 level which I have, I’ve always wanted a tower 3 level.

This has been my dream dishwasher for a long time, my most modern dream dishwasher would probably be a 3rd row stainless steel Whirlpool with hidden controls, they’ve gotten amazing reviews and both arms operate at once every cycle instead of the other ones where the bottom runs for a whole, then the top. I hate that. But my main dream machine I’ve wanted for years was the final production models of the 3 level powerclean or ultrawash design, and this one was perfect. Stainless exterior and white on the inside with the 3 level tower system. Of course I could get a older Whirlpool gold with the 5 level powerclean system which there were very few and rare models, but it featured a stainless interior which looked amazing. There were many Durawash models that had a very similar almost identical exterior than the one in the pic, but the one in the pic was truly a 3 level and it was the nicest of them there was besides the White edition series in the 90s by Whirlpool. They were all amazing machines.

I didn’t really notice any difference in performance between the two when I did it. I know it seems kinda a downgrade but I just wanted to see if it was possible and if there would be a difference in washability. I know some members hate the lower tower but I never had an issue loading around it. The largest pot I have still fits in the corner of the rack just fine and i wouldn’t put anything dead center in the lower rack anyways. If anything I found that the feed for the constant rinse in the upper rack got in the way a few times. On the direct feed middle arm they did angle one of the jets so it pretty much shoots right into the middle so you could load stuff there with no washability issues.

Yours will still be a 5 level system with the tower. The 2nd revision powerclean with the filter under the wash arm has spray jets that back wash the filter which is level 1, plus the jets shooting up from the lower wash arm ( level 2) the jets underneath the upper wash arm for the silverware basket (level 3) the jets shooting up from the upper wash arm (level 4) and the roof deflector (level 5).

Did whirlpool ever sell a stainless steel tank powerclean system under the Whirlpool Gold label? I know they where sold under the KitchenAid label, not sure about the UltraWash label. One of the members here has the TOL Gold powerclean and it is a plastic tub model.

Gotcha thanks for the information, yes they did! I was watching this repair video a few days ago, and featured an older unit Whirlpool. When he opened the door of the machine I was like WTF IS THAT?? It was the powerclean/ ultrawash design, but all stainless steel inside. This model in the video is clearly a Kenmore, but has a stainless interior. Never heard of that until I came across this video lol. Guess they were rare Ultrawash’s . Obviously removing the arm is the easiest thing you could do, and I tapped on the video to see more of the machine itself and was very surprised.

Whirlpool PC DWs

combo52's profile picture

Whirlpool never had a SS interior on their PC models, They were sold under the Kenmore and Kitchenaid names however.

 

I would not count the jets on the bottom of the lower wash arm as a washing level as they do not help wash any of the dish load.

I emailed you regarding a spray arm for the 3 level powerclean/ultrawash system.

Yeah, that was only branded by Kenmore & KA because of theyre slightly more “High End” manufacturing is supposed.

These attachments show the difference between the Direct Feed VS tower wash system, as far as “levels” go.

I think the difference between the 3 and the 5 level was mostly in marketing. The middle arm in both systems sprays down which they count as a level in the 5 picture but not the 3 picture. Also the three level picture is of the first powerclean design without the filter on top. The 3 level one does not have holes under the wash arm but the 5 level one does, but as noted they back wash the filter and don’t wash any dishes. Also of note they are shown in the wrong location in the picture...they are spaying into the sump and not the filter.

Tower feed

awooff's profile picture
Changing to a tower system here seemed like a bad idea but after pondering this - never did i have to replace a lower wash arm support ring, nor similarly the ring on the top of the lower wash arm, nor the top rack wash arm feed tube in the 2 wp pcs ive owned in the past with feed tower! -Had always thought the black rubber boot that fed water up to the tower would wear out although mine never did..

my current daily driver ultra wash top rack feed tube is getting pitted now, just as i did have to replace this same part on my ka years ago..

Maybe the gods will surface another late 80s power clean tower feed wash system to me (with light use) here locally soon!

There is a white ring under the screw off cap of the lower spray arm, the nut that holds it in place. Does that plastic cap need to stay there on the center of the spray arm where the cap goes when I install the black rubber cap for the tower conversion?

Post# 1104689 , Reply# 17   1/15/2021 at 22:49 (1,189 days old) by Cam2s (Nebraska)        

The white ring is the bearing and go under the black cap with the new set up.

This idea came together quick....

maytaga806's profile picture
Almost there! Just waiting for the upper spray arm to come in next week and the conversion will be completed, which of course at anytime I can switch to and from. Put the new wash pump outlet on just to make sure everything was correct and fitting the way it’s supposed to, and all is perfect. Took the feed tube out and ran it quick just to insure that it’s working the way it should and it performed correctly, so I put it all back together for now until I receive the upper arm and is back to the original 5 level system for now, which works amazingly, I was just always fascinated by the 3 level tower design, and I knew it was convertible, and parts weren’t expensive so why not? The upper arm is a pain in the ass to find online, eBay rarely has any, and it’s obviously a discontinued part.

Conversion is complete! This tower system works way better than the lame 5 level, the upper spray arm from the back tube for the 5 level systems just aren’t very powerful compared to the jet stream from the lower wash arm cap that sprays the water up the tower into the upper wash arm, way more powerful. This spray arm spins so much faster than the old one did, cause it has the right amount of pressure and is just a 100% better in my opinion. Works amazing.

I would add those rubber tips to all your tines now before they wear away and start to rust....

wish I would have done this long ago to mine, the tips are so much better on the dishware, cushion and grips....

get the longer ones if you can......

Time caps

+1 for the tine caps! Just capped all mine, next time I’ll cap them from the start. Way easier before they rust and swell.

Thank you I will definitely get some for both racks, this machine is extremely powerful. Ripped off two huge chunks of Teflon off a sheet pan I had on the bottom rack! Absolutely love this machine, dated it correctly and came back as a 2005 model, made in November. These were one of the best cleaning residential machines you could get. This machine was not used very much it appeared, had slight soap scum when I received it and ran vinegar and baking soda on a heavy wash, and repeated the process a few times to ensure it had been sanitized from whoever used it throughout its life before i became the final owner, I can’t stand other people’s grime YUCK lmao. The guy I bought it from moved into a new house locally and it was left by the previous owners, and they had a built in already, but I am thinking that since the paperwork including the manual that came with it tells me that the previous owners of the house had bought that new at some point and saved the manuals, but it’s in like new condition and I’m very pleased with it as this was exactly what I was looking for when I started hunting for a portable dishwasher, I might as well get a used full size for 100$ instead of a brand new small countertop for 300$ ++.
