Hi Jennifer, it's Jack at Dyson.

Like most current Dyson upright vacuums, DC40's brush bar is engineered to shut off for protection if something jams it. Although I appreciate you've already checked the cleaner head for any issues, you might like to do so again following the steps shown in the Support video I've attached. You should then be able to reset the machine.

Please note, the brush bar will never rotate when the machine is standing upright, so please recline it into the normal vacuuming position before testing it. With the machine running, press the silver brush control switch twice.

You may also like to check for any blockages which could be effecting pickup performance. Just follow the steps shown in our online troubleshooting guide: http://www.dyson.com/support/dc40/dc40-multi-floor/my-machine-is-not-working/machine-not-sucking-up-well

If you're still having difficulty after you've given this a try, it would be best if you can get in touch with us directly so our experts can provide further assistance. Dyson upright and canister vacuums come with a 5-year warranty, and if a repair or replacement part is needed we'll be happy to confirm if this is covered.

You can reach the Dyson customer Helpline by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

SOURCE: canister will not release

I've done that.
There is a stem that runs down the center of the cyclone that releases the bottom. You didn't get that stem back in place. The only thing you can do is pry it open, hope is doesn't break, and put that cyclone back together correctly.

I've never broke one, but I had to pull pretty hard. Thought I was going to.

Good Luck

SOURCE: While operating machine, brush does not rotate.

Likely the wires are broken under the left hand cover not a difficult fix. Unplug the machine and remove the 4 torx screws and an access panel at the side of the ball. replace wires with new or re-connect with a splice. ensure wires are long enough to allow movement and you don't trap the wires when you replace the covers. about a 20 min job with the right tools

SOURCE: I take apart and clean my DC17 every 2 weeks. When

The roller is not spinning do to motor or belt not working. If it is the motor then the machine will have to go back to dyson if it is the belt then that is an easy replacement.

My Oreck vacuum cleane won't turn on


I have an Oreck vacuum. My son used it just earlier today and it worked just fine, then just a little while ago a tried to turn it on to vacuum our bedroom and suddenly it won't turn on! I tried plugging it into other outlets but it was no use. My husband takes a look at it and first thinks that the switch is out in it. He takes the handle apart and quickly realizes that it is not the switch that is causing the problem. Then he took the base of the vacuum apart, removes the spin brush part and cleans it off, puts it back together, and suddenly it works! He said that when those brushes get real dirty the motor gets clogged, then it just won't turn on. I'm just happy I married someone who can figure these things out, because even if I knew the problem I'm still no good with a screwdriver, taking things apart and putting them back together again. Hope this works for your Oreck too and it's running again for you soon.

Hi, i took apart filters to clean in my dyson dc25 and put it back together as said...and now its making a highpitch whinning sound


Hi its Darran at Dyson.

It may be worth taking the filter in the ball out and putting it back making sure it has clicked back into place securely.

If you need advice on this, please visit our website at www.dyson.com and click on the support section.

Alternatively, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

Reset button or Fuse on my Infinity?


Ok, I took it apart, cleared the clog out, and put it back together. It wouldn't switch to "carpet". Got no answer on my question. Took it apart again, only I went further. Took apart the bottom - brush out, all inside bottom parts out, cleaned all that part of vac. No clogs down there. Ran the carpet/bare floor switch back and forth several times while I had it apart. Put it all back together and it worked fine. Still didn't find a fuse or reset button...

Hep! My 3 month old Hoover Mach 5 doesn't pick up!


What is happening is the secondary filters, HEPA and the canister all need to be cleaned. This is vital. What the vacuum repair people are keeping from you is that tidbit of wisdom. This particular vacuum is picky about airflow. Pull the canister, and on the body of the vacuum on top of where the canister sits are the secondary filters. There should be a sticker explaining how to remove them. Clean them throuougly, mine was filthy. Make sure you clean the canister by unlocking it and cleaning out the micro holes and the cone end. Mine was completely plugged. Now brush the dirty side of the HEPA filter with the combo tool. Let the secondary filters dry completely (you can blow dry them on cold) Re-install everything, and the vacuum will run like brand new. I vacuumed the whole house after I completed this maintainence and it works like a champ. Don't return this vac until you clean it completely.

Roller brush won't spin (bissel 6390/3910 series)


I just fixed mine. It took me all of 10 minutes. Pull the brush out. Stand the brush on end on the edge of your study work bench/table top. while holding the brush vertical( on end) take a small phillips screwdriver and tap using a hammer on the metal pin you see in the middle of the brush. Keep tamping and the whole assembly will come apart. What you will have then is a long metal shaft, 2 bearings(they are acutally skateboard wheel bearings same number same make). Clean the gobbed up hair with a razor blade and then reassemble by tapping back together. The bearing wont be worn out because they are way too tough for a vaccum. We used ride down hills on them! a ten minute fix wow and you wont have to drive to vacuum shop and spend $$ and time
