Pro Scrub feature on K/A dishwasher |

Today I took apart and cleaned the water line going from the sump to the middle wash arm and up to the upper arm. I also cleaned what is called the 'proscrub' apparatus at the back of the tub. Turns out it is nothing but plastic with no valves so I am wondering how does this feature work? There is a proscrub button on the control pad but since there is no type of valve to control the flow of water to the 4 proscrub nozzles, what does turning on the proscrub button actually do?

Can you post a pic? Maybe an alibi function? | ||

Here is a video I watched to see how to take apart the entire tubing assembly. Starting at about 1:40 into the video you will see where the guy begins to disassemble the plastic water feed which goes from the sump to the top of the machine and shows the proscrub apparatus at the back of the dishwasher. You can see that the proscrub just snaps off and is nothing but a piece of plastic with 2 inlets for the water and then the 4 round shaped disks where the water exists. Since water is constantly being fed through the tubing I would think that the water would always be sprayed through the holes in the proscrub device. So what does turning on the proscrub button on the console do?

Are you sure there is no extra feeding hose for these? because if, it would work the same way as the dishwasher changes from spraying the top and bottom rack at different times. | ||

I took the apart the entire water feed line that goes from the centre of the machine where it feeds the lower arm, along the bottom, up the back and across the top of the machine. This is the only feed line. There are no valves contained inside, so the water has to be flowing constantly which also means that both the middle wash arm and the bottom wash arm are working at the same time - there is no alternating flow.

No, you see in the vid to that the lower arm has kind of, yeah, peak in the middle and it is fed over that line. But maybe the pressure is just increased and anyhow only that way it starts spraying. But why don't you try? Run a cycle without the option and then open up the door fast. If it is just alibi function, it should already spray. | ||

My Kenmore elite has the same feature by another name. When you select the option water is somehow diverted from eaching toe wash arm under the top rack and is sent to the turboZone/ProScrub jets. It does this once during the prewash for 2 minutes and then for about 20 minutes during the main wash. Has quite a bit of calcium bildup which indicates that could be his problem too. He needs to run Lemi-Shine through an empty dishwasher pots & pans cycle.

This is strange indeed! Probably it only works with alternating spray arms, which I believe is a newer feature on Euro dishwashers, probably for ten years now. But you should investigate further, I recommend. | ||

Normaly, the water-diverder here in the EU is built into or near the pump and is just like a screen with different holes in it which can be turned: like one whole going to the top, one to the bottom, and at one time only one is opend. I think it was somehow like that... | ||

My machine has the Pro-scrub option. I have only used it a few times. I don't know the mechanics but it does divert the water to the back spray jets somehow or the other. I question how a stationary spray can do much, but it is used to concentrate the static spray with the moving spray of the lower arms (4). Selecting this option adds about 20-40 minutes to the cycle.
Kitchenaid is not the same as when Hobart owned them, but it is a good cleaning machine, and one of the top performers. | ||

Why should it be always on... ...when there's a push button to enable it? | ||

without a diverter valve of sorts.....I am thinking it is always on......the "option" selected would be like a pots and pan cycle.....just extended longer when selected.....it doesn't actually turn that part of the jets on and off....
and offset gimmick.....it does work...but the impression was that it only turns on when that option button is selected, and maybe some models do go from wash arm to wash arm and then power zone.....this might not be one of them....and youwould proabably have never noticed until this issue came up..... would be interesting to get a plexiglas front for it to see what is happenning..... or better yet Gary..do you have a water proof video camera and a few flashlights.....put that inside and view what happens...really curious at this point.... another reason why dishwashers, like washers, need windows to see what is going on inside......and probably a reason why the dont have them! | ||

I was told that when the option is selected it diverts full force to the jets for a portion of the wash cycle.
Surly there is a tech out there that can explain it to us. This post was last edited 09/04/2013 at 15:25 | ||

It doesn't turn on unless you select the option. I can here the spray not coming out of the wash arm under the top rack when it's being used/on. it's that simple. It doesn't work unless the option is selected. Good grief. I've had 6 years with my machine. I've sat in front of it for many a cycle. I KNOW what it sounds like. And my jets rotate,. a Kenmore exclusive.

Kenmore A Whirlpool brand now? Newer Bauknecht dishwashers do feature rotating jets also... They're red in colour. The system is called power clean... | ||

Appnut,
I know that what is supposed to happen but HOW does it actually work i.e. there is only one tube of water going from the sump to the back jets up to the middle wash arm and up to the upper arm....how does the machine direct the water to the jets and not to the upper arms when there is only one tube?

I usually just lurk here (mostly because I can't ever think of anything constructive to add), but I know the answer to this--there are two metal balls in the "neck" below the pro-scrub nozzles that are shifted by a magnet outside the tank.

Timed segments on my Kenmore elite On Normal wash, the jets run for about 3 minutes in the middle of prewash. then another 3 minutes about 2 minutes into the main wash and then another 6 minutes. I timed it on Pots/Pans cycle tonight. Same sequence as above, but the 6 minute main wash segment is extended to 16 minutes on Pots/Pans. I've only used it one time while on Normal. Otherwise, I've always used it when needed and using Pots/Pans. | ||
