Replacing Smart Mix knob

I am obtaining a replacement Smart Mix knob (broken knob). When re-installing, you say that the Smart Mix valve should be in the down position and knob in Water Only position. But which direction does the horizontal "protrusion" on the top of the valve stem face?

    Oh, ok. I think I understand the re-assembly better. I should remove the valve piston from the valve body, install it in the underside of the Smart Mix knob (in the Water Only position), then lower the top cover back on the unit. The valve piston should then go directly into the valve body as the cover goes on. Yes?

The knob itself will only go in one way, What I was talking about is when you put the top cover back on, the knob should be in the water only position. This way the piston (on the bottom of the knob) will go into the slot correctly.

    Yes, just make sure the knob is in the water only position when you push the top down.

Remove the cap for the flow indicator, then there 6 screws to remove to take off the top, before removing the top, turn the smart mix valve to about the half way point so the piston won't fall off. When you are ready to re-install the top cover, just before pushing it all of the way down, turn the smart mix valve to the water only setting, then push it into place, re-install the screws and the flow indicator parts.

Smartmix bottle


The cap and insert at the bottom of the bottle may need to be replaced, or you could have a problem with the smart mix asm. You would have to remove the top cover to get to it. Does the smart mix knob stop where it is supposed to or does it go all of the way around, if it does, then the stop on the knob is broken.

Is the smart mix valve turning and stopping where is is supposed to, if it turns all of the way around, then it is broken inside the top cover. Try replacing the smart mix bottle insert and cap asm part #2101795 . Make sure that the rubber gasket is on the valeve asm. at thebottom of the smart mix bottle. If not, it has to be on the valve.

I purchased a Pro Heat self propelled Bissell rug cleaner model 7950 from Target wherehouse on 4-26-06. I used it once and all was fine. The next time that I went to use it the smart mix for the cleaning...


I assume that it is spraying water? Is the smart mix knob turning freely from one point to the end? If not then there is a problem with the smart mix asm. With liquid in the soap bottle, push the valve in to see if liquid comes out ok, couild be that the valve is bad. Is the seal on the valve at the bottom of the bottle, it has to be on that and not just sitting in the hole. You might try running a mix of water and vinegar thru it, maybe it is clogged up.

Smart mix valve reassebly and alignment


Have the piston on the screw threads, put the knob on the water only setting, then after the piston is on, turn slightly so it doesn't come off, just before you put the housing all of the way down, turn the knob back to the water only setting and then push the top all of the way down. Turn the knob back and froth and if it turns smoothly, then it should be ok. If you put the top down and it is straight, the piston will go into the slot ok.

Rt. elevator arm replacement


Take off the top cover, then you can replace the elevators, they come both sides in a package, part #2000010. When you replace the top cover, check all tubes to make sure they are routed right so as to not pinch one when the cover is locked down. Also there is a piston that attaches to the bottom of the smart mix valve and that the smart mix knob is on the water setting, then put cover back in place and don't over tighten the screw.
