This other video shows the head coming off and belt replacement: How to replace the dyson belt on Dyson DC25 vacuum cleaner

Hi there, it's Jack at Dyson.

DC25's brush bar will shut off for protection if something jams it. Even if the brush bar looks clean it's a good idea to remove it as shown in the video, just to ensure there's nothing caught in the endcap or anywhere else that could be causing an issue.


The brush bar will never rotate when the vacuum is standing upright, so please make sure you recline your machine into the normal vacuuming position before testing it. With the machine reassembled, plugged in, turned on and reclined, press the silver brush control switch (next to the red on/off switch) twice.

If this doesn't resolve the issue we would be happy to provide further assistance. If a repair or a replacement part is needed, we can also confirm if your machine is within the Dyson guarantee period. Just give the Dyson Customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Hi there, it's Jack at Dyson.

DC25 doesn't have a traditional, user-replaceable belt. Instead, the belt is engineered to last the lifetime of the machine in normal use. The belt is protected by a sensor which shuts off the brush bar if something jams it. If the brush bar isn't currently rotating it's very unlikely to be related to the belt itself.

If you've been unable to reset the machine by removing any threads or hair from the brush bar and endcap, we'd appreciate the opportunity to take you through some further troubleshooting checks to pinpoint the cause of the issue. You can reach us by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

We'll look forward to speaking to you. If a repair or a replacement part is needed, we can also confirm if your DC25 is within the Dyson parts and labour guarantee period.

Please be aware that any remaining Dyson guarantee coverage on your machine could be void if you dismantle the cleaner head as you've described. For this reason we'd encourage you to get in touch directly for assistance rather than attempting a repair.

Hi there, it's Jack at Dyson.

DC25's brush bar is engineered to shut off for protection if something jams it. Once you've checked the cleaner head for any obstructions, and removed any threads or hair from around the brush bar, you should be able to reset your machine as shown in the video guide:


Please note, the brush bar will never rotate when the machine is standing upright. Make sure you recline your DC25 into the normal vacuuming position before testing it.

I'm confident this will resolve the issue, but if you do need further help, please give our experts a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

You may need a new belt if the brush bar motor is working properly. It could be the switch or brush bar motor if the motor does not run .

I could be a switch, belt, brush bar motor or a wiring problem.

Hi Kevin,

Thank you for your inquiry. I am sorry to hear about this issue with your DC25 brush bar. Assuming you have already tried cleaning the brush of any obstructions, following the instructions below may resolve the issue:

1) Plug your machine into the power outlet
2) Locate the grey brush bar button next to your power button
3) With the machine turned off, press and hold the brush button down for 10 seconds
4) Release the grey brush button, step on the foot pedal to recline the machine
5) Press the power button to power on the machine
6) Check to see if the brush rotates
