The brush bar & belt need replacing. It DOES NOT have the knob on the side of the brush bar head. Can you tell me if I can change the belt without also replacing the clutch, and if so, how to do it?

SOURCE: DC 07 BRUSH BAR DOES NOT TURN BELT OK

Stand vacuum up and with it plugged in. Rotate knob between carpet and bare floor and back 5 times leaving it on carpet when finished. Rotate vacuum back from upright position and lay vacuum on the floor, rotating it onto its side. Turn vacuum on.

Hi If your Dyson has a brush protection design - i.e. roller bar on the top of the hood on the left hand side then the DYson can't be repaired by you- serviceman or professional care can replace it.
However if the Dyson doesn't have the roller bar on top of the hood, flip the machine over so that the beater brush is facing upwards, locate three/four screw heads that can be undone with a coin and remove the sole plate assembly. This should give you a clean view of the brush bar, drive belt and dirt channel. Ensure everything is clean espcially if the brush bar has lots of hair or threads tightly corded around. Then locate the drive belt and check to see if it has snapped. Grasp the beater bar gently upwards and the belt and brush can then be removed. Fit a new belt on carefully and check the tension as it will be tight.

It MAY be a clutch issue. I had a similar problem with my DC07 Animal recently a posted a solution elsewhere on this site, but here's the summary. To reset the clutch on my model, recline the vacuum, turn it on it's side and slowly change the carpet/bare floor knob from one setting to the other about 6 times. This apparently reset the clutch and now it works fine. You may also wish to call DYSON. They're very helpful and walk you through troubleshooting before recommending servicing. Their number is 1-866-693-9766. They'll need your model and serial number (located on bottom of uinit).

You don't need to take it for repairs, I just corrected the same problem on the phone with a tech. Have the head on your lap, make sure the end nearest the little belt has the rounded side of the bar facing you. The squared off end faces towards the machine. Place your left hand pointy finger under the bar (the 2 inch bar next to the little belt) and lift up, while finessing the loose end of the bar into place, with the rounded part still facing you. Then it sort of snaps into place. Now, replace the face plate. In the upright mode, starting at the carpet dial, switch the dial back and forth between carpet and bare floor, ten times. (the tech actually referred to this as re-setting the vac. LOL) Plug the vac in, incline the hand, and start. It should work. It didn't for me the first time and made a horrible sound. That meant I had to go and repeat the process again, but lo and behold, IT WORKED! When in doubt, call the tech and don't let them get away from you; have them stay on the line until the problem is resolved.
