Brushbar doesn't spin though good vacuum.
Have taken apart. No belt. Brushbar is driven directly by
Johnson U-5640 motor. http://www.johnsonelectric.com/mediando/index.php?IdProduct=525&IdTreeGroup=49
Motor is 120 VAC nominal drive, but motor output of circuitboard,

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
Look for the reset button on the side of the brushbar housing - there should be a red sticker and a red button. Push it once. It's not gonna stay depressed, it's gonna pop right out - that's normal. - Step on the red pedal on the back - Turn the machine on with the red power button - Press the gray button next to the red power button - this is the ON/OFF switch for the brushbar - if it doesn't spin, press and hold the gray button down for 10 seconds - If it still isn't spinning, remove the brushbar and make sure nothing is blocking it and withholding it from spinning this link is for the manual.. http://media.dyson.com/downloads/UK/floorcare/Manuals/DC24_allfloors_uk.pdf
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.
This is extremely embarrassing, but if I can save you some frustration, I'll gladly swallow the humble pill. I had the same problem, after vacuuming an area rug, the brushbar quit spinning. I let it cool to ambient temperature and tried again, thinking that the auxilliary motor that turns the brushbar may have overheated and tripped a thermal cutout. I even took the unit apart and inspected the brushbar motor to ensure the windings weren't damaged and that the brushes properly engaged the communtator.
Ready for the solution? There's a button right next to the power button that has a picture of a brushbar on it. Guess what it does? It turns the brushbar on and off. I cycled that switch, tried again, and: Ta-dah! It worked.
