I have a Dyson DC17 that has started making a loud noise when on carpet when the brush is engaged but not on hard wood when the brush is not turning. I have remove all the material (hair,lint, etc.) wrapped around the brush itself, but it is still making the noise

Have you correctly replaced the glider that covers the brush? You need to make sure that the clips are fully seated .

Probably the brush bearing. Consider changing the brush assembly

It is probably the brush roll motor making the noise. Remove the brush roll & belt and turn both motors on. If you do not hear the noise when both motors are running the noise is likely coming from the brush roll

Hi Ed,

I'm sorry to hear you're having difficulty with your DC17. It's worth checking that the new brush bar and belt are fitted correctly, and rotate freely. The video attached may help in making sure it's correctly aligned.

It's worth checking that no threads, hair or debris are caught within the machine. The brush bar motor itself isn't designed to be serviced, and we would advise against attempting this in case further damage is caused. I'd encourage you to email our experts directly with our contact details - you can reach them at [email protected]. Someone will be in touch as soon as possible to take you through some diagnostic checks to confirm what's causing the noise.

If you'd prefer to call our customer Helpline, you can reach us on 1-866-693-9766.

Best wishes,

Hi Deb,

I'm sorry to hear you're having difficulty using DC17 on this particular carpet type. DC17 is engineered to adjust automatically to different floor types, and does not need manual height adjustment.

Carpet manufacturers sometimes recommend vacuuming deep or delicate carpet piles with the rotating brush bar turned off. We'd recommend checking with the manufacturer of your carpeting as they'll be best placed to offer advice on the correct way of cleaning it. To turn off the brush bar on DC17, just use the silver brush control switch next to the red on/off switch.

It's also worth checking that the soleplate is fitted correctly. Any dirt or residue on the soleplate can be removed with a damp cloth - make sure it's completely dry before refitting it. You can find out how to remove and replace it here: http://content.dyson.com/support/help.asp?article=962&product=DC17-ANIMAL

I hope this helps, but if you would like further advice after you've given this a try, please email your details to [email protected]. One of our experts will be in touch as soon as possible.

Best wishes,

Jack

probably a flat spot on the belt, replace the belt

Loud noises are usually caused by worn belts, unbalanced roller brush or debris in the roller brush. Check these things. Here is a link to the belt you need:

Dyson DC17 Replacement Belt

On a Dyson this engages the brush bar. Two possible faults: Debris (hair etc) caught in brush bar - cut out with knife. Or - damaged drive belt - pieces of belt striking casing. Last, but unlikely cause, debris in bearings of brush bar - replace brush bar.
