I got my Little Green ProHeat when the product was first unveiled
several years ago. Shortly thereafter, the nozzle itself developed a
clog in the spray jet. Remove the nozzle from the end of the hose, and
with the machine running pull the trigger. If a great amount of
solution comes out of the supply hole, then your nozzle is clogged.
You can try clearing it with a very thin pin and then rinsing it out.
In about 6 months, my pump would no longer spray solution at all but I
could hear the tiny pump still running inside the machine when I would
pull the trigger. Remove the tanks, unplug the unit, and look
carefully and you will see the few screws holding the unit together.
Pull it apart carefully and don't use much force as some of it snaps
together and you don't want to break those tabs. Once open, you can
find the solution pump, a little fella. The drive shaft on the motor
that spins the pump had rusted away completely! Design flaw. In lieu
of getting it repaired, I simply started using a spray bottle for my
solution application. Several years later and I'm ready to take the
time to replace the pump - a very simple process. From the research
I've done, the part number for the solution pump is:
Manufacturer's Part Number: 6035029
If you google search "Bissell 6035029 VacPartsWarehouse" without the quotes, you should find your part there for around $9.

Click item #9. It's very simple to install. If you can wield a
philips screwdriver, and pay attention to how you've disassembled the
unit and then just reverse the steps, you can fix this yourself on the
Good luck! :)
