Dyson DC08 Cylinder Bagless Canister Cyclonic Vacuum

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

As the cleaner head and filter fills with dirt and debris over time, all the built-up debris begins to emit a burnt-smelling odour. You may need to remove and clean out the vacuum`s filter. We need to advise you to stop using your machine and request that you contact your local customer support team.
If your Dyson vacuum cleaner is making a loud vibrating or revving noise. First thing to try is empty your bin and make sure there are no blockages, if that doesn`t solve it then remove the brushbar and then try switching your Dyson back on again.
If there is a strong burning smell coming from the motor area of your Dyson DC14 or DC07 then it is most likely that your motor has burnt out.
Blockage – when a vacuum cleaner becomes unusually loud, it is normally because of a blockage of some sort. This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well.
If you`re smelling rubber, the belt has either burned out and snapped or the belt has become so stretched out that the roller is not moving and the vacuum belt is getting super heated from the motors RPM.
If you park your automobile in a safe space and listen to the engine, you might hear sucking sounds that sound a lot like a vacuum cleaner if you have a vacuum leak. Sometimes a leak can also make hissing or squealing sounds.
Your Vacuum Pump Is Noisy

Sometimes, extra noise can mean that there are pieces of debris stuck in the system rattling around. It can be an easy fix—just locate and remove the debris. A loud pump could also mean you have worn bearings that need to be replaced or lubricated.

Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filters need washing or your machine is blocked. Carry out the performance checks, and if your machine cuts out unplug and leave for at least 2 hours to cool down.
Sadly, most Dyson cleaners do not feature a reset switch. So the best way to resolve the problem is to unplug the machine and let it rest and cool down for a minimum of one hour. This automatically resets the appliance and makes it ready for use.
Worn out bearings on the brush roll will make a vacuum much noisier. This is a good time to check them after cleaning and inspecting the brush roll. Try spinning each bearing by hand. Some brush rolls have only one bearing on the roll, and the other bearing is in the head where the roll is mounted.
Typically, when a Dyson doesn`t pick up and has no suction, it is blocked. Dysons make a loud hissing sound when there is a blockage in the system somewhere. The DC50 is the same in this regard. Dyson publish a simple guide that covers checking your filter, checking the wand isn`t blocked, etc.
If your vacuum cleaner had a strong acrid burning smell before it lost power then the chances are the motor has failed which will require a motor replacement.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
Engine Noise

If you hear a ticking or tapping noise in your engine, the most likely culprit is the valvetrain. This could be due to a low oil level or the need for an oil change, or it could indicate more serious mechanical issues – such as the need for an oil pump replacement.

You`ll likely hear squealing or hissing sounds from air sucking through cracks in the intake manifold gasket or vacuum hose. Luckily, these sounds are hard to miss unless you play music a bit too loud.
Hissing or Sucking Noises

Usually, when the leak isn`t too bad, you will hear hissing noises coming from the engine. This may also sound like whining sounds or whimpering sounds. For more severe vacuum leaks, the noise is sucking or suction, much like a vacuum cleaner.

An engine has a lot of moving parts, and a car making loud noise when accelerating could indicate engine problems. For instance, worn valves can make a clicking noise that`s more noticeable the faster a vehicle moves. Bearings, which let the cam and crankshaft spin, can also be noisy when they start to fail.
Mounting an incorrect vacuum pump can cause severe and expensive engine damage.
This could be an indication that the motor is overloaded. If the pump is buzzing you should turn it off straight away before the motor burns out. Usually, the capacitor has failed to result in the buzzing sound. The capacitor is what serves the motor power.
Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filters need washing or your machine is blocked.
Clean Your Dyson Vacuum:

Thoroughly clean the dust bucket and flapper by shaking or tapping it to release any dirt that has become clogged if your Dyson is pulsing, stopping, or making noise. Rinse your filter monthly, even if it looks clean on the outside.

Clear out hoses, attachments, and brushes of any hair, dirt, and debris. This will allow for restored airflow and should get things going again. Make sure there are no cracks or broken belts impeding the system from running optimally.
Safe management system. Our unique battery-saving trigger helps maximize run time – only using power when you need it. It ensures the battery does not overheat or overcharge and catch fire.
To reset the Brush bar press the Brush bar control button twice or switch the machine off and back on.

HI , I REPLACED MOTOR BRUSHES ,BUT MOTOR IS MAKING A FUNNY NOISE ,AS IF MOTOR IS LOOSING CONTACT ,LIKE A BURNING SMELL. CHEERS
ANSWER : Hi there,
.Most likely you have a damaged commutator. I used to change the brushes on the dyson vacuums but what i found is that it is almost never completely successful. THe Dyson motor is not as good quality as say a miele and when the brushes go they normally cause damage to the commutator. THe best bet is to replace the motor. If you were able to swap the brushes a motor change will be easy for you. If you are in Australia you can get the motors from VacuumSpot or Nelson Vacuums.

Motor is sparking and smells like burning rubber. When it first happened I thought the vacuum had something jamming the beater bar. That was the smell it had, like when the belt gets burned. But when we turned it over, it wasn’t jamming. Took off the base plate and turned it on. The motor area is sparking and it makes a weird noise (I assume that is because the motor fails and restarts). I looked for loose wires, can’t find any. I believe I need some sort of part replaced, maybe even a n
ANSWER : From sound and description most possible is motor is burnt up sparks usually mean metal on metal either bearing or bushings went on motor if u can jiggle the shaft thats bearing if u rotate the shaft by hand and feel and or hear rough grinding the brushes are damaged and the (windings)are also would need to replace motor oreck has a costumer service 800 989 3535 number give them a call not always but some times they will ship a replacement part for free

Bad Motor I have purchased two of the Kenmore direct drive beltless systems with Progressive systems. The first died after a year, the vacuum motor start making a grinding noies. I pulled the side HEPA filter and could see a fine coating of graphite like dust. Took it to a vacuum repair shop. They said the brushes were going and thus the motor was shot. I liked the vacuum and bought a second, 1 year later the motor is making a slight noise that and removing the HEPA filter I find a slight metall
ANSWER : That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.

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!
ANSWER : 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.
.Next turn the dyson dc04 vacuum cleaner upside down and remove the base plate this is done with a large flatblade screwdriver.
.The next step is the brush – you should be able to access the drive shaft and pull the belt off which will free the roller.
.Unclip 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.
.Next 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.
.Now you should have basically a “nude’ dyson
.Next 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.
.There 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.
.From here your on the home straight.
.The 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.
.With 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.
.Reversing 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.
.Hope this helps. if you need more tips hit me on the website NelsonVacuums.com.au

Vacuum making high pitched noise and smells like motor is burning
ANSWER : Try repair first for quote and if too expensive then replace. 5 years is about the average life span.

When I vacuum w/ the brush control in the on position it make a really loud noise, almost like a grinding sound. I have looked at it and nothing seems to be wrong, but I notice that the pin that engages the belt seems to vibrate a bit, possibly creating the noise. It started when I accidentally got part of a plastic grocery bag caught in the brush. Could it have stretched a belt? Nothing is caught any other place and it only makes the noise when the brush in in the on position.
ANSWER : Yes, the belt could have been stretched and is now vibrating and hitting other parts and creating a noise if much of the bag got caught under the belt. If you have another belt for this vacuum, please put it on and see if the noise stops. If it does, then problem solved, if not let me know and we can try something else and you can send a picture or video to me of the problem.

Let me know how this works out for you.

Electrolux Hi-light Hi, my hoover is making a weird knocking noise and emitting a burning smell. Took the lid off and the belt *seems* okay, but still makes the noise and the smell….
ANSWER : Burnt smell is probably the belt slipping. Even though it looks OK, either the belt needs replacement and/or the roller needs cleaning and/or lubrication at the ends. Try cleaning the roller ends first and then light lubrication with WD40. If belt works, you are done. If not, replace belt.

Hi. I have a DC 24 which when brush rotates makes a very loud noise. I have replaced the brush and side bar. The side bar appears very loose. The noise stops when I switch the brush rotation off. Any ideas ?
ANSWER : Hi there,

I’m sorry to hear you’re having difficulties with your DC24. If the cleaner head seems to be making an unusual noise during use, you may want to check all the parts are correctly assembled, and that the cleaner head and brushbar are free of obstructions. The video below may help in doing this.

If you’ve tried this and are still concerned about the noise, please get in touch with us directly, as we should be able to determine the cause of the noise over the phone, and provide further assistance. You can call us free on 0800 298 0298 (UK), or 1-866-693-9766 (US) – it will help if you have the machine to hand when you call.

Best wishes,
