Question about Hoover F7431-900 SteamVac Vacuum
If the screen is not dirty, and the flapper valve to the turbine inlet is open, then the problem is mostly a stuck turbine impeller. The turbine impeller on my F7431-900 has seized TWICE!! The shaft for the turbine is not made of stainless steel, therefore is subject to corrosion. If you have a handy husband or boyfriend, give it to them, because some disassembly is required to access the turbine unit. After the turbine is removed and opened up, get some P'Blaster and squirt is on the shaft. P'Blaster is a rust removing solvent and is great for freeing up rusty nuts and bolts. Allow the P'Blaster 20-30 minutes to penetrate the corroded shaft. Then, grab the impeller and wiggle it back and forth, until free rotation is achieve. The last time my brushes stopped rotating, and I disassembled the turbine, it was really siezed up. I thought I was going to need to buy a new impeller assembly. But, that P'Blaster is really great stuff for breaking up corroded parts (it's like WD-40 on steroids!). I did need to give the turbine's impeller a good twist to free it up. If you can't get the turbine impeller to rotate, then buy a new one (about $27.00). Then, you can just install it and save a bundle on labor. I think I want to become a Hoover vacuum repairman. Their business must be booming because Hoover is putting out a poorly designed turbine unit. Boo, Hiss...... shame on Hoover for selling us **** like this.
PS You can get P'Blaster at any auto store, like Pep Boys, Autozone, etc.

I had the same problem. Turned out to be so simple. Look down at the machine. On the right is the green spiral to indicate the wheels are turning. Right above that is a cover that can be popped off to allow access to a small filter. If the filter is blocked, air intake is blocked, and the brushes will not turn. Mine was clogged. Took the 2 seconds to remove the material and the machine was fixed!

There is a plastic cover on the bottom of the unit you have to remove. Two screws on the bottom and one in the top part of cover...squeeze in the ends at the back of the cover..remove it....Now llok at the spped control lever(off,lo,high) Did that plastic lever(with a slot in it) come out of the plastic button that suppose to go into the slot.If it jumped out,put it back in ( it is spring loaded.) This regulates the Off,Hi,and Lo positions. Sometimes when this lever lifts out of the connecting button, the spring loaded control arm will sometimes go the the "OFF" position,(Although on the machine it can say in "HI" position when it's really not,and therefore will not turn the brushes. KAPISH ?

Open unit's bottem cover and look for the following: - Motor works - Belt which transfer motor's movment to the brushes, in place and not broken (most frequent phenomenon). - No mess on brushes axis which prevent their free movement. Good luck !
