Hoover steamvac turbine and brush control switch

The brushes on my f7425-900 stopped working months ago and i found out it maybe the turbine causing the problem. So, i got the turbine off the machine and found that the shaft and bearing was froze solid with rust. I soaked it in oil and and got it loose and cleaned it up and put it all back together working properly. After putting the machine back together and turning it on i pushed the brush control button to the on position to start the brushes but nothing happened. Is there any suggestions of where to go from here?

    ive found the problem on my hoover steam cleaner being the turbine gears were rusted. I cleaned them and oiled them down well and now there turning perfectly but when i put the machine back together and turned the brush switch on the brushes still would not turn

  • mathis_23 Jul 16, 2008

    there is only one filter on this model f7425-900. no other filter exist. Im wondering if it could be the switch on the turbine that turns on the brushes although i dont see how it could be since there looks to be no significant wires or nothing hooked on the switch. Just one long piece of metal attached to another that moves by spring actions when pressed forward.

  • mathis_23 Jul 16, 2008

    ive received some advice that the problem could be that the carbon brush or motor windings probably have gone out with the turbine froze for a long time. Is there any advive out there to replace or find and repair this carbon brush or motor windings on my own?

  • mathis_23 Jul 16, 2008

    I do not think there is a belt drive on this hoover model shampoo machine

  • mathis_23 Jul 16, 2008

    i seriously need help out there if any assistance is available. I thought i had everything figured out when i unfroze the turbine gears and cleaned and re-oiled only to come to the conclusion that the brushes would still not turn even with the machine on and the turbine in great condition now. I have no clue if there is or where a belt drive is on this hoover model f7425-900. In addition to knowing where to look for and how to replace a carbon comb that has burned out from not being able to turn. Help please!!!

  • mathis_23 Jul 16, 2008

    sorry for not accepting the advice yu gave initially ive just gotten frustrated working on this machine for 6 hours and finally thinking i got it fixed with the turbine problem. Is the motor comb in the engine? How do i get to it and take it apart?

  • mathis_23 Jul 16, 2008

    How do you get to the motor on the hoover f7425 steamvac to to check on a carbon comb?

  • mathis_23 Jul 16, 2008

    How do you find the carbon brushes in the hoover steamvac and replace them?

  • mathis_23 Jul 16, 2008

    Basically, i can hear and feel the motor running. As a matter of fact it will still try to **** up and release water upon usage just no brushes wil turn. I took the entire brush unit out and its still intact. There is no blockage of the blocked hole on the bottom of the unit that the brush unit snaps into. I checked the turbine and found out it was froze. I cleaned and oiled it thoroughly to where the bearings and white teethed wheels would spin again. Then placed it backed on the unit correctly along with the rest of the pieces and turned on the machine and still did not spin the brushes when turned on. I found out how to get to the motor and did not notice any carbon combs. At this point i have no clue.

  • mathis_23 Jul 16, 2008

    Somehow by a miracle i pieced the unit back together again and the brushes started spinning. Dont know how but they wont turn off if u push the switch to off. Do you think its possibly that switch going bad on the turbine and it would be best to just get another turbine?

  • mathis_23 Jul 16, 2008

    Also can a turbine from a model hoover f7226-900 work on a model f7425-900 model?

  • accountant23 Apr 17, 2009

    The brushes on my Steamvac Dual V F7222-900 quit spinning only a short time after we got it. After cleaning the brushes, making sure the lower left switch was in the correct position (you know, all the things you're supposed to check) I suspected it might be a problem with the turbine after doing a google search and seeing it listed frequently. I tried unscrewing a few things to try to look at it, but can't find any diagrams anywhere (not in the manuals, websites, etc.) Is there an easy way to check out the turbine?

Hi,

There are two (2) kinds of brushes involve in your vac. The first would be the circular ones (5) that do the actually cleaning. the 2nd would be the electrical brushes more commonly called carbon brush. These provide the electrical contact to the commutator segments of the motor. It initially, when the motor was stuck, then it would be very likely that these carbon brushes have burned themselves (if not the motor windings themselves) up. Pls check/replace the carbon brushes. In some instances, they may have been inadvertently wired/positioned the other way around.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    The rating you gave my solution "Thanks for Trying" is actually a rejection (perhaps unknown to you) and would normally discourage any follow-up suggestion(s) and/or that you would rather hear other possible solutions.

    Nonetheless, with your indulgence, I am taking the liberty of providing additional information by way of images below. Pls note that the carbon brushes should connect/touch the multiple slivers of commutator segments. These are generic examples of carbon brushes and vacuum motor.

    and hi again,

    A couple of clarifying questions pls:
    1. do you hear/feel the motor running?
    2. if yes (motor running), is it just the bottom set of brushes that do not spin?

    If yes to #2, The scrubbing unit on the bottom snaps off as a single unit. The entire unit is powered by a single square post driver that snaps into the power part of the unit and makes the wheels spin. It is possible that the post had snapped off, rendering the entire block of six spinners useless.

    If no to #1, pls consider that it may be cheaper/faster to replace the entire motor. Pls reference this page. Carbon brush replacement would require of course that you be able to get/buy the correct brush. Remove the motor, dismantle the motor.

  • Louie  Role
    Louie Role Jul 16, 2008

    Based on your recent comment/postback, we can eliminate the motor/carbon brushes and need to focus on the drive of the bottom brushes.

    Allow me to repost "...The scrubbing unit on the bottom snaps off as a single unit. The entire

    Hi,

    To my knowledge, the switch for the bottom brushes is a mechanical one (not electrical). This would mean that the switch actually pushes on a long slide/bar the engages/disengages the square post driver from the gears.

    My compliments on being able to make it work, I would like to forward a guess that on your initial assembly, the driver post did not fitted itself to the slot in the gearings which was corrected on your subsequent re-assembly.

    Re on "turbine from a model Hoover f7226-900 work on a model f7425-900 model". Just might, yes. basically the same design, the same housing, the same capacity.

There are filters, one on the lid, the other from the bottom, has a red frame, pull it out and clean it. There maybe a foam filter on the lid covering the yellow ball, it needs to have at least a 1/4 in. gap from the top. Also make sure that the lid is on correctly and tight.

The brushes still do not turn fast.


Take the brush block out, make sure it turns easily. If it does that is ok and obviously the turbine is too. Suction would be your problem next. Check the tank to be sure it's sealing correctly. The clear access panel on the front of the hood can also leak or have blockage in it. It is the screen behind the clear panel below the brush speed control. There really isn't much else to cause you problems with the brushes. It's either suction or mechanical.

Brushes donot turn when asked to shampoo


The brushes are turning by an air driven turbine. The turbine has a pivot bushing made of steel inside of it that gets rusty because of the water that is running through it. The turbine will have to be replaced. You can find a genuine hoover replacement part by following the link below.

Hoover steam vac model f7425-900 filter is


The brush system on this model has a poor engineering design in that the brushes are running off an air turbine, which uses a steel bushing to spin the turbine which gets rusty from the moisture when the machine is being used. No long term solver. I would replace the machine with a Dirt Devil Platinum Force model

Hoover Steam Vac - Brushes not turned, no suction power


The Brushes not spinning is most likely is caused by seized bearings in the turbine, requiring shop service (easy fix). The suction issue can be caused by the standpipe seal missing or lower recovery tank not on properly, on some models missing front panel. I would need more exact model info to assist further.

Brushes not working


brushes not turning are usually caused by the turbine bearings have seized. The turbine cost is about $35 average. on the bottom you can check a pull out filter to clean. there are also 2 screws that are recessd check by hand for tightness that hold the turbine. checkthe brushes for cleaning and free of debris. check the square shaft on the brushes as well. take it to a trusted vac shop who works on hoovers if you are not mechanically inclined for this type of repair.

Hoover brushes wont turn


Is the shaft on the brush block or did it break off, if it did, replace the brush block. On the top, left rear corner is a lever that moves baack or forward depending on the handle being upright or tilted back for usuage. Is it moving? If not then you have a problem there. Otherwise if the square hole doesn't move when it is turned on, and the lever is switch to the on position, then replace the turbine.

Brushes not working


Check the filter from the bottom, it has a red frame, pull it out far enough to clean it, if it is clooged, then the brushes won't spin. If it is clean, pull the brush block out, make sure the shaft that goes up into the turbine is not brokked off, if it is replace thebrush block. With the brush block out, turn on the machine and look up where the brush block goes, there is a square hole, if it is turning, then it is ok, if not, then the turbine is either clogged up or the turbine has gone bad.

Belt replacement Hoover carpet cleaner


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.
