Loud whining when the dyson goes on and off


Dyson vacuum cleaner - Strange noise troubleshooting.
WHISTLING NOISE
If you are getting strange noises from your Dyson vacuum cleaner, listen very carefully as each one is telling you something different. Look through the list and see if you can spot your strange noise.
If you are getting a whistling noise, that usually indicates an air leak (vacuum leak) of some kind.
If you also have a loss of suction, make sure you check for blockages, torn seals, or parts not fitted correctly such as u-bends etc.
A seal may also be missing so go through our poor suction troubleshooting and see if you can spot where the suction dies.
If you try all of that with no luck and have a machine that has a HEPA filter like the DC07 or DC14 especially, then remove the HEPA filter and check the circular seal underneath the HEPA filter. If this has moved even slightly this may be causing the whistling, try removing the seal and putting the filter back in.
The DC24 and DC25 ball models are known for this, you turn the machine off and it gives off a strange revving/flapping noise. To diagnose this properly then remove the HEPA filter (the one in the ball) turn it back on and off again. If the noise has gone then replace the HEPA filter with a new one. Go to our parts store to order one


POPPING NOISE

A popping noise accompanied by a really pungent burning smell 99% of the time indicates a motor failure with your Dyson vacuum cleaner.
This will involve a motor and usually a post motor filter replacement as it usually burns the post filter or at best traps that lovely smell in the filter for eternity.
Sometimes a popping noise is a bit simpler.
All Dyson vacuum cleaners are fitted with something called a bleed valve, if the Dyson becomes blocked the bleed valve opens allowing air to get to the motor so it doesn't get too hot and fail.
The bleed valve on most models makes a popping noise, clear the blockage and/or wash your filter and that should solve it.
Go to our suction problems page to troubleshoot it.

RATCHET NOISE

If you hear the dreaded ratcheting noise it'll scare your kids and pets and make you switch it off immediately. It sounds like a football rattle but worse.
The ratcheting noise only happens on Dyson vacuum cleaners with a clutch.
Don't know the difference?
Look at the two models below, the one to the left does not have a clutch the one to the right does.
Still don't see it? Look at the bottom left of each machine, the purple ones have a purple dial meaning it has a clutch (could be any colour dial) the yellow one doesn't.

Anyway, back to the ratchet noise. This usually only happens when something is obstructing the brushbar, it stops the brushbar to prevent the belt from breaking (clutch belts cannot be replaced by the customer) and makes the ratchet noise to warn you.

Removing the obstruction, like a sock or paperclip from the brushbar will usually get it working again.
If you remove the obstruction and it still ratchets, then unplug your Dyson and try turning the brushbar by hand. It should be quite loose, if not remove the brushbar by grabbing it and twisting and pulling until it comes out.

When you get it out try turning it if it is still tight then remove the end caps and check for dust or hair build up in the ends and also remove any hair built up around the brushbar. Spray some WD40 in the ends if necessary, put the end caps back on the brushbar and try again. If it is still tight to turn then I recommend a new brushbar.
If the brushbar is spinning freely by hand then the odds are it will require a new clutch. We sell these in our parts store one clutch fits most models, the only exception is any DC03 and the DC04 Zorbster model. We sell all clutches and brushbars in our parts store

LOUD VIBRATING, SCREECHING OR REVVING NOISE
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 the noise is normal again then it is your brushbar or possibly clutch if applicable. Remove the brushbar, cut off any hair, remove the end caps of the brushbar and apply grease, WD-40 etc to the bearings. Put the end caps back on again and try and spin it, does it spin freely? If not then the brush may need replacing.
If the noise remains with the brushbar removed then I'm afraid it is a motor failure and will need a motor replacement.
If your motor fails with this noise usually it is down to the filters not being washed often enough and dust choking the motor.
If you have one of the ball model Dysons, such as DC15, DC24, DC25 etc. this could be your brushbar motor, brush bar or the end cap!
Best thing to do is remove your brushbar and end cap and inspect them. Any obvious sign of wear or damage then replace them. Also inspect the part at the other end of were the brushbar sits (this is the brushbar motor and drives the brushbar) Is it worn or damaged? If so you will need a new brushbar motor.
Try switching it on with the brushbar removed and the brushbar motor turned off at the switch.
Is the noise still there? If yes then there is a good chance you need a new main motor (not brush bar motor)
If your answer was no, try switching it on with the brush bar motor on (will need to be in the leaned back position for this) Is the noise still there? Yes, then you will need a new brushbar motor.
If your answer was no again, then replace your brushbar and end cap.
One more thing to try with the DC24 and DC25 ball models is to remove the HEPA filter (the one in the ball) switch it back on and off again. Has the noise gone? Yes, then the HEPA filter needs to be replaced.

Dyson DC07 belt change has resulted in very noisy vacuum!


Hi I agree with the first 2 solutions above but not the 3rd one.
If you have suction coming through the hose when the machine is in upright position then the u bend has nothing to do with this problem.

Right so ... The belt snapped.

The answer to you question is "why did the belt snap" its true that it could just be old age but its more likely to have been caused by a foreign object being sooked up.

How the belt/brushbar/motor interact

Your belt simply connects the motor to the brushbar know as Direct Drive. If an object get inside the space between the motor and the brushbar or if it can jam the brushbar then this will cause the rubber to burn. The motor will keep spinning and the belt wont be able to so will snap.

So its easy to see that the belt has snapped and people just think "'oh the belt has snapped"

You might wonder where im coming from here.

Anyway because the brushbar got jammed it may also have been buckled slighty either as a result of the foreign object causing it to stop suddenly from spinning at high speed or/and the result of the heat build up.

The rattling noise you now find your Dyson making is more than likely because your brushbar is buckled and when it spins the bristles are hitting the housing unit.

Your belt will snap again unless you replace the brushbar

Dyson dc24 no suction at head of cleaner, the hose has good suction and the brushes are not spinning


Hi Janice,

If your machine has no suction from the cleaner head, I'd recommend that you check the machine for blockages and reset the brushbar. To locate and remove any blockages, please follow the steps shown in our online Support guide:

http://www.dyson.co.uk/support/dc24/dc24-multi-floor/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/filter-washing-video

To reset the brushbar, please follow the steps shown in the video below. The brushbar will not rotate when the machine is standing upright, so please recline it into the vacuuming position before testing it.

This should resolve the issue, but if you need any assistance locating the blockage, please call our Helpline on 0800 298 0298 (UK), or 1-866-693-9766 (US).

Best wishes,

Jack

Why is my vacuum DC 17 Animal shut off when I switch brush to floor mode?


Hi there,

I'm sorry to hear you're having difficulties with your DC17. The brushbar on/off switch shuts the brushbar off for cleaning hard floors - however, the suction motor should continue to run. If the machine shuts off completely when you press the brushbar on/off switch, we'll need to arrange to have the cleaner serviced. To discuss this with one of our experts, please call us free on 1866MYDYSON, or email askdysonUS@dyson.com.

Kind regards,

The floor suction brushes are not rotating and not picking up, the suction on the hose is fine. it a dyson dc25.


Hi there,

I'm sorry to hear you're having difficulties with your DC25. Your cleaner is equipped with a safety device which shuts off the brushbar if it gets tangled with a rug fringe, shoelace etc. After making sure the brushbar is free of threads, hair or other obstructions, you'll be able to reset the cleaner and get the brushbar running again. The easiest way to do this is to follow the steps shown in our guide:

http://www.dyson.com/support/help.asp?article=1156&product=DC25-ALLFLOORS


Please note, the brushbar will never rotate when the cleaner is standing in the upright position, or if you've turned it off using the silver brush control switch located next to the red on/off switch.

By following these steps, you should be able to resolve your issue without further assistance. However, if you've tried this and are still concerned, it's probably best if you get in touch with us directly. One of our experts will be happy to run through some troubleshooting over the phone with you, and will be able to recommend the best course of action. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

No suction or very little, gets hot after about 2 minutes of use and shuts off


Ensure there are no blockages by disconnecting the tube. Is the brushbar spinning? If not, your can take the brushbar off and clear obstructions. Let me know if any of these are issues. If not, I have some other suggestions.

DC24. Why won't it turn on?


J Luke, it's not fully clear what the issue is - no power at all, or that the brush won't spin. The manual can be found here (
https://www.dyson.co.uk/medialibrary/Files/Dyson/Support/downloads/UK/floorcare/Manuals/DC24_Manual.pdf ) and a Dyson graphic for resetting the brushbar is here (
Reset brushbar ) A very common issue that a lot of people don't pick up on from a first perusal of the manual is that the brushbar will not spin when the vacuum is in a full upright position (this is what switches the suction over to the handle/wand, and no use spinning the brush with no suction, so it turns off). You may want to try again with the vacuum back inclined from upright. There are some models where part of resetting the brushbar after a blockage is to press the brushbar switch (grey switch next to main power switch according to forums, though not pointed out in the manuals) several times.

Other forums say that if something has actually failed, it's a PCB about 1% of the time and the actual brushbar motor the other 99%. That swap would go into a lot more detail than likely needed here.

Good Luck!

The brushbar is not spinning.


Even though the belts are intact they can still be stretched and will not turn the brush. Here is a link to the belts you need:
