Question about Bissell 7920 ProHeat Pro-Tech Upright Wet/Dry Vacuum
Does water squirt out of the hose nozzle, if it does, then check the heater inside the handle asm. Make sure that where the tubes hook up to it are not clogged. If water doesn't squirt, check for the seal at the bottom of the tank, it needs to be on the tank, not in the hole, this is for the soap bottle, there is a seal on the bottom of it as well. The flow indictor cap is leaking air or maybe is too tight. If you had the top cover off, make sure that the tubes are routed right so as not to get pinched when the cover is put back on, the smart mix knob should be in the water setting and that the piston is on the bottom of the smart mix knob. Pump is bad. Try running a mix of vinegar and water to see if that unclogs the lines. Is the top cover and the base tight together in the back, sometimes the top breaks loose and it will raise up and it can't spray, just re-fasten it down.

My clean water wouldnt spray. I also felt that the tank wasnt sitting right in the machine. As suggested by reddevil6, the rubber seal was in the bottom hole on the machine rather than on the water tank itself. Had to pull it out with tweezers and re-fit it onto the water tank.... problem solved.!!!

The repair facility will tell you to buy a new machine. But here are the
things you should check first:

If you are able to get water through the hand tools hose, then your pump is in good condition- if not, it sounds like a pump gone bad, otherwise it sounds as if your heater has a blockage or you have a crimp in a line somewhere. I have written a hopefully helpful manual for the BISSELL 7901-1, I will gladly send you a copy of it, though I would appreciate maybe a dollar or two for my time- email email@example.com and if you feel generous, send a dollar or two to paypal firstname.lastname@example.org. If you don't think it''s worth a dollar, just email me and I'll send you a copy of it (must have a valid email address)

If I may! In most cases the heater is clogged. It might be clogged with soap that has harden over time. You need to take the handle apart. You will see a metal box(thats the heater) besides the wires there are two tubes connected to the heater. remove the tubes but label or watch which tube goes where. now turn the heater upside down. there are 6 screws on the side and 1 in the middle. remove them carefully. the 6 on the side have a small gaskets under them..you don't want to lose them. the 1 in the middle has no gasket, now the bottom plate of the heater can be taken off (there is a gasket with that plate ...be careful . you will now see the long channels inside the heater and need to clean it. the holes where the tubes where connected have to be clean also but carefully. the metal is soft.so it bends. now put it all back. hope this helps. if you want to keep this from happening.the best way is to run clear water after you are done.this will remove any soap in the machine which will harden after the machine drys out. hope I helped .
and to mr. reddevil6 I am learning lots from you. Thanks

Thanks to many others who have posted on similar problems -- water
and/or solution sprays through the handheld tools, but not through the
As others have suggested, I removed the water reservoir, which exposes the 2 main water sprays mounted above the rollers. Using, pliers, I carefully slid the clips back. Gently but firmly removed the two red nozzles.
Elsewhere I have read suggestions to just do one nozzle at a time. However, I found out that if you remove both red nozzles, you can then blow through one side and it will come out the other. In my case, that dislodged a nice collection of crystal-like chunks (guessing it may be crystallized residue from the cleaning solution).
There was also a bit of blockage in one of the red nozzles, which I cleaned out. Make sure you can blow through both of them with little resistance.
Reassemble: Push red nozzles back into hoses. Using pliers, reposition sprung clip back over the red nozzle. Snap nozzles back into place. Refill tanks and power it up.
In my case, that resolved the problem of no sprays from the main machine. Sprays like new now. Hope yours does too!! g

The sprayer nozzles could be clogged with some foreign obstruction and may need to be pulled out and cleaned. You could also have a kink in a hose within the motor/pump compartment area that needs to be released or air blockage. You can unscrew the top from the base (unplugged of course) approx. six phillips screws and see if there is a kink in a line and you can still start the unit /power up and view water in lines going to nozzles in /under the unit.

It is very simple and inexpensive to fix. All you need to do is replace the pump belt. Here is the belt you need:

One pointer that can help between uses is running water through the lines. First, put clean water in both tanks and set your unit to the heavy traffic setting for one pass. This will flush out any cleaning formula in the lines so your spray tips won't get build-up between uses, which can lead to a lack of dispensing the cleaning formula.
