Question about Hoover F7431-900 SteamVac Vacuum

1 Answer

F7431-900 HOOVER STEAM VAC

Brushes stopped moving. Put screwdriver in where brush shaft goes to see if it spins. It does not. I was told probably a bad turbine. I can not get the top cover off. I removed all the screws I can see but there are 2 points at the back of the cover about center of the wheels where the cover is attached. I can not see how to get those points detached. Specifically, the very back 2 points of the top cover (about center of the wheels) attach to brown blocks that seem to lock into the very back of the base. Can not figure out, any help would be appreciated.

    I have the same problem. I keep the Sears warrantee. This is the fourth time the turbine has been replaced. Hoover needs a recall on this model. I think the consumers and better business should be contacted so no one else has the same problem.

Same thing happened to me. There are 2 more screws you're probably missing. My turbine has seized twice !! Need to clean out the corrosion. But, now I want to know what is the best lubricant to prevent corrosion in the future.

    Also, the cover is only secured with 3 screws. One on the top and two on the bottom. The bottom two are located on the black plastic section and are deeply recessed.



    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.

My brushes on my Hoover Steam Vac stopped spinning again! I took the brushes out and they turn fine, but when inserted back into the base, they do not turn, AGAIN! Anyone know what the problem is and...


Tip is slightly, do the brushes spin then? If so, then the brushes are air driven. By the spin indicator at the front of the machine, you'll see a small screen (same type of thing as is in your dryer), scrape it, you'll probably find there's a build-up of fluff. Clean off the fluff, and try again.

The brushes will not turn but the shampooer will come on


1) check the filter by the spin indicator (the plastic cover snaps off). Clean if necessary. See if this solves your problem.

2) take out the spin brush assembly (pull out, there may be tabs you need to push to get it all the way out. Clean out dirt and hair. This may be all you need to do, if not take step 3

3) turn on the machine with the brush assembly out. Do you see where the square shaft the drives the brushes goes in? If the socket does not spin, you probably have a seized up turbine assembly.

4) remove the top that covers the motor/turbine (you probably have to take out some screws) The turbine assembly is towards the front. Remove this (again, a couple of screws) and turn it over--there will be some gears. If you can get these gears turning smoothly together you should get the turbine working again. I used a pair of pliers to turn the metal shaft.

Put everything back together and try it out!

I own a hoover steam vac model f5915-900 and i currently have two problems. 1. the brushes are spinning at a much slower speed. 2. the steam vac is not picking up the water it leaves on the carpet....


the reason the brushes are not spinning is because the belt is slipping, the belt is the bad that connects to the brush to a shaft that makes it spin. Next problam is it is probobly clogged. so water is not going through all the way

Brush Disassembly Hoover STEAM VAC Owners Manual F9514-900 (F9514900) does not
explain how to take the brush assembly apart. The instructions are as
follows:

Figure 1 shows the key

which are held onto the

white inner piece with 3

tabs each. The clear

Hoover steam vac, brushes won't rotate, have cleaned filter by brushes, removed brushes and they rotate okay when off steam vac, tried to ajust level for carpet cleaning and brushes still don't move


Check to see if the shaft on the brush block hasn't broken off. Otherwise it is the turbine that drives the brushes and is either clogged up inside or needs to be replaced.

If this is a Hoover Steam vac, the turbine which drives the brushes is bad. If not a Hoover, then what is it, they are different, need brand and model number.

Brushes do not spin on my steam vac


We were having the same problem with the brushes not spinning.
How I fixed it:
I Removed the brush assembly by gently pulling on both sides of the assembly. I took a wide slotted screwdriver and inserted it into the slot (hole) that turns the brushes. At first it did not want to move. I GENTLY applied pressure by turning the screwdriver to get the gear to move and it began to move freely. I spun the gear a number of times using the screwdriver to make sure it was moving freely.

I reinstalled the brush assembly by aligning the gear that slides into the slot and gently pushing the clips back into place using equal pressure on both sides.

I plugged in the machine and the brushes now spin!

Good luck to everyone out there!

This happens when the filter on the inside of the lid for the dirty water tank is pushed all of the way up. You need to leave a 1/4 in. gap from the top to the top of the filter.
