SOURCE: need a user manual for a bissell proheat pro-tech 7920
Go to bissell.com type in the model number 7920 then go to user guide and you can print it.
The 7920 is a 220 volt version of the 7901. I found a shop in New Zealand of all places that has service manuals on line. They are sort of picture books, but using them has saved me a lot of money as it makes repairing much easier. Here's the link you'll need. Good luck. If you need any more help, just add a comment to your post and it will go to my e-mail and let me know. The heads you clean are just the outlet spray heads when they get gunky.

Looks like you already have the USELESS Bissell advice list!
Thanks to many others who have posted on similar problems -- water
and/or solution sprays through the handheld tools, but not through the
main machine.
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!!
SOURCE: My bissell proheat pro tech 7920 does not use any
It may be the valve in the base of the machine, not the valve in the bottle. Flush well with clean water. Sometimes the jets get a little clogged up - especially if you don't use bissell solution - or if they get dirt in them. I cleaned them and mine worked again.
