Hair around belt area

www.sewvac.com Remove the bottom plate and disconnect the belt.If it still makes the noise it is the lower motor that drives the brush that is bad.If it dosent make the noise try cleaning off the hair and debris from the motor pully and replace the belt you will need to take the brush out to do this.While the brush is out check the ends for binding they should turn smoothly with very little resistance also check the area the belt rides on the brush and make sure there is no dirt buildup in the area the cogs of the belt ride in. If it is the lower motor and is less than 5 years old call Dyson and they will generate a work order for a service provider.It may very well be under warranty. !-866-693-9766

You need to replace the belt. Here is the belt you need and a manual you can view which has instructions:

Dyson DC17 Belt and Manual

The drive belt has probably broken. You can get a replacement belt here:

Dyson DC17 Belt

there are 4 screws on the base plate then slide out the brush then you can put the belt back on

First check to see if the gray plate that you removed to access the brushbar is back on the machine properly. Also, make sure that the long black strip on the plate is on properly and is not making it harder to push the machine.

Lastly, you are able to remove what is called a "ropeseal" from the bottom of the machine which will allow more air to flow underneath the machine. This won't affect the suction power of the machine.

To remove the ropeseal, take the gray soleplate off again and have a look at what would be the inside of the plate - you'll see a long, thin piece of rubber/foam that looks like a rope/string sitting in a groove all the way around the openings that the brushbar bristles stick through. Remove the seal and keep it in a safe place. Your machine will be easier to push now.

Remove the plate over the brushbar. Gently clean out debris. Put plate back on,plug in and turn on vac and press brush bar button to reset.

on the bottom plate are 3 spots, one in the center and one at each corner, that need a flat head screw driver to loosen. turn left to unlock, this will remove the plate so you can clear the debris from the brush.

sounds like you may have alot of hair or thread wrapped around the bar, this can stop it if there is enough, have a look at the beater bar (brush)

I was having the same trouble and it was driving me nuts.  I tried cleaning and it did not work.  Then I tore the brush assembly off and looked up into where the little tooth gear is.  I saw something that did not look right.  There was a silver roller bearing laying down below the assembly.  I got some tweezers and found it was not attached to any thing.  I then cleaned out the pet hair and saw a spot where this roller goes that takes the slack out of the brush. It is a pain and takes alot of trying with pliers and prodding  with a screw driver, but I got the roller back where it goes.  It does not attach very solidly, but I put every thing back together and it works great so far.  It is a definite design flaw.  I found that you have to keep the main unit on  the floor when the brush is running.  Do not do stairs or pick it up and do couch cushions, that is when the bearing breaks loose.  Dyson needs to figure out a better design for this.  I was lucky to figure it out, but it is very hard to get to.  Again never pick up the unit when the brushes are engaged.

Go to a DC14 there is a reason why Dyson calls it the Animal. It's ment for all the pet hair and things like that, listen to what Dyson recommends you, they know their products well.
