Is the noise still there? If yes then there is a good chance you need a new main motor (not brush bar motor) Try switching it on with the brushbar removed and the brushbar motor turned off at the switch. 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. Any obvious sign of wear or damage then replace them. this could be your brushbar motor, brush bar or the end cap!īest thing to do is remove your brushbar and end cap and inspect them. If you have one of the ball model Dysons, such as DC15, DC24, DC25 etc. 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 the noise remains with the brushbar removed then I'm afraid it is a motor failure and will need a motor replacement. Put the end caps back on again and try and spin it, does it spin freely? If not then the brush may need replacing. Remove the brushbar, cut off any hair, remove the end caps of the brushbar and apply grease, WD-40 etc to the bearings. If the noise is normal again then it is your brushbar or possibly clutch if applicable. If your Dyson vacuum cleaner is making a loud vibrating or revving noise.įirst 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. We sell all clutches and brushbars in our parts store We sell these in our parts store one clutch fits most models, the only exception is any DC03 and the DC04 Zorbster model. If the brushbar is spinning freely by hand then the odds are it will require a new clutch.
If it is still tight to turn then I recommend a new brushbar.
Spray some WD40 in the ends if necessary, put the end caps back on the brushbar and try again. 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. It should be quite loose, if not remove the brushbar by grabbing it and twisting and pulling until it comes out. If you remove the obstruction and it still ratchets, then unplug your Dyson and try turning the brushbar by hand. Removing the obstruction, like a sock or paperclip from the brushbar will usually get it working again. 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. If the noise has gone then replace the HEPA filter with a new one. To diagnose this properly then remove the HEPA filter (the one in the ball) turn it back on and off again.
The DC24 and DC25 ball models are known for this, you turn the machine off and it gives off a strange revving/flapping noise. If this has moved even slightly this may be causing the whistling, try removing the seal and putting the filter back in. 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 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.Ī seal may also be missing so go through our poor suction troubleshooting and see if you can spot where the suction dies. If you are getting a whistling noise, that usually indicates an air leak (vacuum leak) of some kind.
