Vacuum brush stays on when dyson 44 attachment is attached but not turned on

SOURCE: Dyson DC07 Original won't pick up at base

Hi,

Lie machine on its side pull back handle as if vacuuming & switch on (KEEP YOUR FINGERS & ANY LOOSE CLOTHING CLEAR OF BRUSH ROLLER)

Brush should spin if it doesnt ensure clutch control knob on side of machine is in drive position if it isnt rotate knob by hand to drive brush should now spin.

If it doesnt & your machine has A clutch either clutch will need replacing or belts will need replacing.

Manuals are available to replace belts & remove the clutch from this site http://dysonmanuals.llc.nu/index.htm

Yes I had the same problem on my animal Dysom. There is a button on the top of the dysom that turns the cacuum on. Right beside that button is another one that turns on and off the brush!!! Good luck!!! I accidently one day bumped that button and couldn't get my brush to work but after troubleshooting it, that was my solution.

Apparent common failure is that either the thin yellow and or blue motor drive wires that run from the LH side of the vacuum where the "control board" is located down into the hinge / ball area become stretched and then fray and eventually break. Happened to my Dyson twice. First repaired under warranty, second took about 20 minutes. You need a Torx screwdriver to remove the LH panel ( 4 screws) and also an access panel (2 screws) at the side of the ball which permits access to the blue / yellow wire connectors. I replaced with a new wire and connectors having fed the wires through the access hole making sure sure enough wire was available for the movement of the handle. Also ensure that when the covers are replaced they do not trap any wires underneath.

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.

My vacuum had this exact same problem, but was out of warranty because it was remanufactured. Thankfully, it's a very quick, five-minute fix.

1. UNPLUG The Vacuum!
   
2. Remove the cannister.
   
3. Extend the handle and remove it.
4. Remove the two torx (T-15) screws behind the power button, where the handle normally stows.
5. There are four tabs holding the front plate containing the power button on; use your screwdriver to release them.
6. Gently pull the front plate off.
7. The switch on the right is the power button. Remove it, try clicking it a few times; if it sticks, great! Replace it and reassemble, otherwise you'll need to replace it.
