    Hi there,
    I am sorry to hear you are having difficulty with your DC17. If the brush bar is not spinning it may be obstructed.
    Please visit for step by step instructions on how to inspect your brush bar and clear any obstructions that may be present.
    Once you have carried out these steps you may need to reset your brush bar. To do this please plug your machine in, recline it as if you are preparing to vacuum a carpeted surface, turn your machine on and if the brush bar is not spinning push the silver button next to your power button one time. This should reset the brush and it should begin spinning immediately.
    If you are still having difficulty with your machine please contact the Dyson US Helpline at 1-866-693-9766 or the Dyson UK Helpline at 0800 298 0298 so we can provide further assistance.
    Best wishes,

      SOURCE: My Power head on my Dyson Animal DC39 will not stay spinning. Suction Issue?

      There should be a red insert on the right-hand side on the cylindrical bulge behind the brush cylinder. Check that this is moving when you push the button. The red insert should stay pushed in for the brush to rotate. The insert moves in an out as well as rotates in order to lock in the 'in' position. Mine is a little sticky on the rotation and I need to shake the brush head a little in order to get it to rotate and lock.

      Why won't the brush on the head stop spinning?

      Hi Glen, it's Jack at Dyson.

      Depending on which DC39 variant you own, you may have the facility to shut off the rotating brush bar using the trigger control on the hand grip. The brush should be shut off when cleaning hard flooring, delicate rugs or long pile carpet. Press and hold the button for a few moments to shut off the brush bar:


      If you've tried this and cannot shut off the brush bar, please contact the Dyson Customer Helpline directly. Our experts will need to take some further details about your particular machine, and will also be able to talk you through some simple troubleshooting checks to resolve any issues.

      Brush bar doesn't spin on dyson on dc39

      Hi there, it's Jack at Dyson.

      DC39's Trigger head floor tool is powered by a turbine, driven by your vacuum's suction. Following these simple checks should help you resolve any issues which could be preventing the brush bar from rotating as normal:

      Get the brush bar to spin again on my dc39 vac

      Hi there, it's Jack at Dyson.

      The rotating brush bar inside DC39's Triggerhead floor tool should rotate when the vacuum is running, unless you turn it off using the button on the wand handle. If it's not rotating, our Support guide will walk you through the checks needed to resolve this:

      In the unusual event that these checks don't resolve the issue, please contact our experts directly so we can help you further. 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).

      Why won't my dyson DC39 vacuum beater head stay on?

      Hello, this is Ava with Think Crucial.

      There are a number of reasons why your brush roller has stopped moving. General maintenance to your vacuum is crucial and will help it work at peak performance.

      First things first lets focus on the brush roller. Unplug the vacuum and turn it on its side. Look for any noticeable clumps of debris or hair strands that may be caught in the brush roller. Remove these obstructions, probably best to do so with a scissor if it's hair or long pieces of carpet fibers. After removing the debris try manually rotating the brush roller to uncover other hidden clogs. Another thing to take note of is the condition of the bristles on the roll itself. Are they loose or worn down? These are signs that your brush roller is in need of replacing.

      While checking out your brush roll you might as well take a look at your vacuums belt. Your belt should be replaced about every three months. After regular usage, the belt will stretch out, lessening the tension on the brush roller. Lesser tension diminishes the brush roller's turn rate and speed. If the belt feels loose then it certainly is affecting your vacuums suction as well as your brush roll not moving at all.

      When I turn the vacuum on there is no suction and when I then go to turn it off it sounds as though it is backfiring. It is a Dc39

      Hi Robyn, it's Jack at Dyson.

      From what you've described, it sounds like your DC39 is blocked. This would prevent the machine from picking up as well as it should do, and will cause the relief valve to activate, making the 'backfiring' noise you've mentioned.

      We'd recommend checking the floor tool, telescopic wand and hose for blockages. If you can't find any, it's likely the blockage will be in the duct hose. Our Online Support guide will walk you through how to clear this:

      It's also a good idea to give the filter a wash, as shown in the video attached. This should be done at least once every three months in normal use. We recommend using cold water without any detergent, then allowing the filter to dry completely for at least 24 hours before replacing it.

      I'm confident this will resolve the issue, but if you would like any further advice from our experts please email and we'll be in touch as soon as possible.
