Go to your owner's manual, page 12. Remove the belt cover pieces and inspect the function of the belts and brushes, turning them by hand to confirm mechanical connection to the motor. Find the inoperative part and replace it, then simply reassemble the unit and start cleaning your carpet. ;)

Hoover steamvacs don't use belts. If the brushes are not turning, pull the brush block out, turn the machine on and see if the square hole where the brush block was, is turning. If not then the turbine is bad. Sometimes you can take the turbine apart and clean it out. most times I have found , replace it.

"I did some research online and the recurrent theme was a bad turbine assembly. Fortunately I was able to fix this myself which took about 2 hours (some reading) and little effort. The problem was with the turbine which is fairly simple and had a bearing that had rusted and froze up. Removing the cover proved to be more difficult than fixing the stuck bearing. This was mostly due to figuring out the correct screws to remove and finally discovering that the back of the cover (over the wheels) is not secured by fasteners but by pegs that "pop" out.
Once I had the brush assembly and Cover removed the turbine came out with the removal of some obvious screws and gently pulling the hoses from the assembly. After carefully opening the assembly housing I discovered the bearing problem and with a little lubrication and some new grease had it working in short order. Putting everything back together was simple as well."
this worked for me. although once i got in i just had to mess around with the gears and loosen them up. getting in was the hard part soo here you go peoples.
take off tanks
unscrew 6 screws fom underneath machine. look carefully
just underneath where the dirty tank goes right by the part that sucks everything up is a screw. unscrew it
pop off the switch for your spin scrub mode. it pops right back on.
make sure your locks for the tank are turned in
then the back just pops off. you might have to give it a good tug. there are no screws although it maight look like there is.
then pull off the grey part.
once inside it is pretty easy.
but if you have any questionbs email at [email protected]
i took off so many more screws than i needed to to get this figured out so dont do that.

You are on the right track! Place a screwdriver (flatbladed) into the white drive square and try to turn it. If it is locked up the drive assembly is your problem. It is very common for these parts to lock up because of the moisture involved with these machines. The only way to fix this is by replacing the drive unit, simply remove the hood of the machine and you will find 4 screws and one hose hold this drive in place.
If the gear assembly turns just fine you have a problem elsewhere. More than likely it has something to do with the dirty water tank. All the drives and pumps on these run off the suction created in the recovery tank. I would remove the tank take the lid off and then place it all back again. Then attempt to run the machine.
If the tank is on fine, the white gear turns ok and the brushes still will not turn:
Time to go back and inspect that brush block. The drive tab may be brolken off too short, or something else to do with that particular part.
In the case you can find nothing wrong with any of this, i would contact the local hoover warranty service center. A locator is on the hoover website. Hoover picks out the best vacuum dealers to service their product, for a small fee they would probably be able to tell you just what is wrong with it.
Best of Luck!

To help out here the hood has 6 screws on the underside of the machine and 2 post snaps at the rear of the hood. They pop out when lifting the rear of the hood. The air motor is as described above, 2 on bottom and 2 on top. When removed the air motor again has 2 screws on the cover of the gear set and a couple clips which come loose readily when the screws are removed. This exposes the gear set. Remove the gears and free the air motor shaft. Clean, lubricate and reassemble. You should be good to go. The Air motor is the only weak link in the machine. The bearings seize due to exposure as moist air is pulled through the air motor to drive the gear set. Great idea! Hoover should have used a stainless drive gear and bearings or a plastic bearing that would hold up to the RPM of the motor. Regardless, as is it will be plagued with the problem for the life of the machine unless you upgrade. Hoover may have solved this for all I know. Hint: The motor will not create any torque until the suction tank is in place. Oh, and keep the screen clean. That is the motor intake.

I just brought mine home...assembled per instructions and tried all the troubleshooting thus far to no avail. So I popped off the brushes per instructions and took a screwdriver to the hole where the brushes axle inserts underneath the vacuum and turned the whole manually. This either a) loosened it a little from the factory or b) moved the blades that the centrifuge was forcing to more optimum positions. In either case, the blades started working. note: when you turn, you should feel some resistance. As others noted, if it doesn't turn at all, turns way to freely or doesn't turn smoothly, then it's a bearing issue.
