Having problems with your Vacuums ?

Dyson DC04 is making a grinding sound & smells of burning. Hi. I have been told that the above is due to the carbon motor brushes burning out. The brush at the bottom still turns ok. I have bought 2 new carbon brushes & wondered how I would go about replacing them. Any help would be much apprecieated!

Hi there SmartAlec from NelsonVacuums.com.au here, this is not a repair for the faint hearted. First i am assuming you are not using a clutch model - with a selector for carpet/hard floor on the side. If you do have that model i can give you extra instruction. First you will ned a torx driver (like a phillips head but with a star) size 15. Remove the clear bin, the hose that runs up the back of the vacuum and the filter cover and filter. Also remove the inspection tube at back of machine and anything else that pops off easily.
\015\012Next turn the dyson dc04 vacuum cleaner upside down and remove the base plate this is done with a large flatblade screwdriver.
\015\012The next step is the brush - you should be able to access the drive shaft and pull the belt off which will free the roller.
\015\012Unclip the small hose which goes from soleplate to the back of vacuum and remove the soleplate itself you will need to apply very firm pressure and only pull each side out a little way because if you go too far you will crack the guide.
\015\012Next is to remove the housing that holds the whole brush assembly. You will see on either side of the vacuum 1 plastic washer (like a circle with a bit taken out) which has to be removed. Once both are off you can gently slip off the body over the shaft that the washers held the body on to. This removes the the body part that moves up and down to adjust your dyson to different height carpets.
\015\012Now you should have basically a "nude' dyson
\015\012Next step is to remove the 8 torx screws that are spaced around the motor housing. The plastic outer will now come away revealing the last bit of motor casing.
\015\012There is a cover plate that is held in by 4 lugs that can be gently pried back with a small screwdriver and the lid will come off like a tupperware container.
\015\012From here your on the home straight.
\015\012The motor now needs to be pushed out of its little case. The large rubber gasket will make this quite hard as it it designed to hold the motor in but with a fair bit of pressure it will slide out.
\015\012With the motor out it should be easy access to the carbon brushes they will simply screw off allowing new ones to be screwed back on.
\015\012Reversing the process is as simple (after youve done a few) as reversing the instructions and keep in your mind if you have to apply a lot of force it is likely that something is not lined up properly.
\015\012Hope this helps. if you need more tips hit me on the website NelsonVacuums.com.au

I just bought a used euro pro steam shark model ep903, has all parts but when I turned it on to use it water and steam poured out of the handle grip area. Am I not doing something right? The manual says to attach the brush directly to the hand grip but I can't use it without getting burned. Any suggestions would be greatly appreciated! Thanks!

Stopped running My mother's Oreck vacuum sound as if there was something bogging the rotating brush down. I pulled the bottom cover off and found nothing wrapped around or restricting the brush. I tried to finish vacuuming with the problem then I turned it off to move a chair and turned it back on it would do nothing.

Bought a new sweeper and brush ( beater bar ) does not turn. The large belt is fine and turns. The small thin belt is also fine but does not turn the brush. It is either the wrong belt or is there something that could be missing to put tension on it ?? Thank You [email protected]

How is the V-belt tension adjusted (Hoover Model U6439-900)or how do I know if the tension is correct? There seems to be a lot of "play" in the belt and I'm wondering if that is the reason the brush roll only turns as the wheels turn, regardless of the carpet height setting. And yes, the brush roll is set for carpet, not hard floor. Or is the cause of the problem something other than the V-belt? A new flat belt was installed when the machine was professionally serviced so I assume (?) that was a


The V-Belt is not adjustable. There are two ways the belt has no tension: (1) when the handle is upright, a mechanical lever takes the drive tension off the belt, and (2) the brush roll lever setting you described.

Kirby Vacuum Hi Bruce, In my opinion, yes the Kirby would be worth it, as long as you are not replacing the motor. The switch would be the most expensive part besides the motor that would need to be replaced. The switch costs USD 49.99, the cord is roughly $39.99, and the carbon brushes are $29.99. I can easily walk you through any of these repairs should you need help. Kirby's are great vacuum cleaners, that usually last 30+ years. Brand new these machines sell in the US for $1600 or more,

There is one way to verify if it is the switch.It's kind of dangerous though,but not too bad.You need an extra piece of wire,fairly thick.I would use 4 guage myself.Hold it with pliers,just in case it gets hot.Turn the switch on and hold the wire to ... Rainbow Vacuums

My Dyson Root 6 made a loud banging sound, and now its motor emits a strong burning smell every time it's switched on. It runs for a second or two, making a lot of noise, and then stops. (Just bought a new battery for it, too - what a drag...) It's off warranty, and Dyson wants almost as much to fix it as a new one would cost. Is my Root 6 e-waste, or is there anything that can be done for it?

Burning smell how do I get the bottom section apart to clean it out- burning smell when i have the spin brushes turned on. Any help would be appreciated cause I love this machine and hubby told me it couldn't be taken apart to be fixed. Thank you.


The bottom doesn't come apart. you have to remove the top cover to get to any components. But if you have a burning smell, then it is probably ther motor and would have to be replaced. Motors cost anywhere from $70 to $90. ... Hoover SteamVac F5914-900 SpinScrub Upright Vacuum

I have a Eureka 4870GZ. It turns on, but the brush roller doesn't move. The belt looks fine. I do have an extra belt and would try replacing the old belt, but I can't get the old one off the motor shaft or the new one on. I called Eureka customer service. The lady said there's supposed to be a small space between the motor shaft and the outside edge of the vacuum where I can slip the old belt off and the new one on. I don't see it. It looks like the motor shaft goes into a recessed place in the

I have the Eureka 4870 "The Boss" Smart Vac. The beater bar began to turn constantly and can't be shut by moving the Brush Roll Contol to Bare Floor position or the machine to the upright postion. It has also eaten two new belts. A local tech says he has seen this problem whereby the free-wheel assembly that makes contact with the belt to engage the beater bar is misalgned and cannot disengage. It is usually the chassis which would mean replacement of enough parts that would not be worthwhile

I have a Eureka 4800 series the Boss upright with a bag and Hepa filter. I love it! I was just vacuuming with the hose part and all was well and then suddenly the lower brush came on and a "burning" smell followed. Thought it was the belt so my husband was going to put on the new belt which I had on hand! When he turned it over, the "bar" that holds the belt looks as though it "shot through" the plastic side of the housing on the vacuum. There is melted plastic on the outside of the vacuum and o

Hello, I have a problem with my Eureka Powerline bagged upright vacuum. It has a 12 amp motor and is model #4352, Type D. It was probably bought new in 1998. My problem is, while vacuuming today the motor seemed to slow down all of the sudden and then began smelling like burning rubber. I shut the vacuum off to check for blockages but could not find anything blocked. When I then turned it on again it runs but seems to only be running at 1/2 the motor speed and still has the rubber buring smell.


It sounds like a rubber sealing in the motor has come loose and is being constantly rubbed against the walls of the motor with would cause the smell and loss of motor speed caused by the fricton of rubber against the rod so if you can get to the moto ... Vacuums

I'm using (or WAS using) a Eureka ''the boss'' model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can't find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?


First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes. ... Vacuums

I have a self propelled Royal Dirt Devil vacuum model number 087900 and it goes backward fine but forward has to be pushed so hard it's impossible. Is this a switch? Do you know about how much the part would cost and can it be done by a beginner. We fix a lot of things ourselves but we aren't mechanics by no means. We put a brand new belt on it. I don't think it can be put on backwards and brush turns fine. Where is the switch? Use layman's terms.


You might try a new belt and/or brush roll. The brush roll is what helps pull a vacuum forward, the power drive helps, but if the brush isn't turning like it should, then it will hinder forward motion. The belt may look ok, but they stretch to the ... Vacuums
