Question about Bissell 1699 ProHeat Clear View Upright Steam Vacuum

3 Answers

Can't reassemble!!! Long story as short as possible- I removed the hood from my Bissell 1699 and can't seem to get it back on correctly. The "Smart Mix" knob and it's parts seems to be the problem. How does this line-up, or what is the best way to put it all back together? Thanks, Josh

    Thanks so far, but how exactly does the piston go on the bottom of the knob? It seems the small grove might somehow fit onto the threads of the knob. For lack of a better way to explain it, the top of the piston looks kind of like the blade of a hokey stick. If you can explain it using this analogy or if you have a better way that's fine? Where should it end up in the slot (if your looking at the front of the machine the slot has two stopping points- 6 o'clock & 7 o'clock)? Should I use a small piece of tape or something to hold the piston in place durring assembly? Thanks so much for your help!

    Take the plunger part out and place it up in the screw shaft, it will kinda shim in on an angle then drop straight. Then when you drop the top down into the bottom, the shaft will drop into the hole. It slides up and down slong the threads. Very unintuitive.

The piston is put on the bottom of the smart mix knob, turn the knob to the water only setting, then put the top housing back in place making sure that the piston went into the slot, after the top is all of the way down, turn the knob, if it turns easily, then it is in place.

    With the knob in the water only setting, angle the piston on it will go on the threads, turn knob alittle so it will stay on. Start to put the top on, just before you let it go all of the way, turn the knob to the water only setting, then push the top down, making sure it is going on straight, the piston should go into the slot, then push all of the way down. Turn the knob and if it turns smoothly, then it should be ok.

A little hint.....there is a slot for the piston to fit into beside the knob. to get it there, turn the knob just past (about a 1/2") the water only setting. If you are watching from underneath , you will see that you can lift the knob slightly out of the way, just enough to slide the piston into position. hope this helps!!!!

Both answers above will get you going. The small slot that looks like an axe kerf is what the screw ramp on the solution knob works against. The long ear on the needle valve runs up and down in the slot racheal is describing. I had to take my cover off again to align the vacuum port. I put the solution valve on full soap position. The needle valve didn't drop out and was easy to reinstall. HTH

MOD 1699-f reassemble cleaner fluid mix switch


This is one of the most difficult machines to work on, but I can help you to reassemble the the "Automix Assembly." There is a black piston with an O ring on it that has to be put in place before the hood is put back on. This part will actually set inside the windings on the smart mix knob, before the hood is placed on the machine, and as you place it on the machine, the piston will have to slide down in the hole on the automix. Getting the piston into the windings can be a little tricky. You might have to play with it a bit and it doesn't lock into place. It just sits in there loosely, just enought to hold it in place while you put the unit back together. It's hard to describe how to place the piston in the windings of the knob, but I'll give it a try. Hold the hood upside down and place the squared corner of the piston into the squared corner of the hood between the knob and where the solution tank would sit on the opposite side. Now you can turn the know and screw the piston down into positon and the hood is ready to install.
Hit: put a book or peice of 2X4 under the unit between the rear wheels to lift the wheels off the work surface and help line everything up. If the hood doesn't feel like it is seating into place correctly, something is wrong. Very important on this machine: if even one hose is slightly out of place it with not pump. If it doesn't pump alway check the attachments to see if they pump. It they don't, then you might have a clogged heater.

Good Luck

Replacing Smart Mix knob


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.

Make sure that the piston on the bottom of the smart mix valve is in the water only position.(needs be be on the knob and not sitting in the hole). With the top off, it is easier if you have a block of wood or something under the base to hold it up. Other wise it drops down and the screws can't grap the base. Also make sure all hoses aren't being pinched.

The piston needs to be on the bottom of the smart mix valve, and the knob needs to be in the water position when you put the top cover back in place.
