Why does the Dyson brush bar spin then stops, and how to fix it?

Here are reasons why the Dyson brush bar stops spinning on carpet and hardwood floor and how to fix it:

The Brush Bar Is Stuck

If the brush bar becomes stuck, it can cause the spinning to stop. This can be caused by debris or foreign objects getting caught in the bristles, or the brush bar itself may be damaged or misaligned. To fix this issue, you will need to remove any debris or foreign objects causing the brush bar to become stuck. You can turn off the vacuum and use a pair of tweezers or a similar tool to remove the debris gently. If the brush bar is damaged or misaligned, you may need to replace it.

Blocked Wand Or Bin Inlet

Another reason your Dyson v8 brush bar spins then stops is a blockage in the wand or bin inlet. This can occur when debris or dirt becomes stuck in the inlet, preventing the brush bar from spinning correctly. This can also cause overheating, as the motor may work harder than normal to try and overcome the blockage.

To fix this issue, the first step is to locate and remove the blockage from the wand or bin inlet. This can be done using a small brush or compressed air to loosen and remove any visible dirt or debris. If the blockage is not visible, you may need to disassemble the device to access and remove the blockage.

It is also essential to regularly clean and maintain the wand and bin inlet to prevent future blockages. This can be done by using a small brush to remove visible dirt or debris and then using compressed air to blow out any hidden debris. Regular cleaning and maintenance can help to prevent future issues with your Dyson brush bar.

Stuck Transmission Rod

The transmission rod is the component that connects the motor of your Dyson vacuum to the brush bar. If this rod becomes stuck, it can prevent the brush bar from spinning. This can be caused by various factors, including debris or dirt trapped in the rod itself or a misalignment of the rod in the vacuum’s housing.

You will need to access the vacuum’s transmission rod to fix this issue. This typically involves removing the base plate of the vacuum, which can be done by unscrewing the screws that hold it in place. Once you have access to the rod, check for any debris or dirt that may be stuck in it. You can use a small tool to remove debris, such as tweezers or a toothbrush. If the rod is misaligned, you can gently move it back into place.

Once you have cleared any debris and realigned the rod, you should be able to test the brush bar to see if it is spinning correctly. If the issue persists, you may need to replace the rod, which can typically be purchased from a Dyson service center or an authorized retailer.

Worn Belt

The belt is responsible for turning the brush bar in your Dyson vacuum cleaner. If the belt is worn or damaged, it may cause the brush stops spinning after a few seconds, as it cannot maintain the necessary torque to keep it spinning. To fix this issue, you will need to replace the belt. You will need to locate the belt cover on your Dyson and remove it to access the belt. Then, simply remove the old belt and replace it with a new one. Make sure to match the new belt to the old one in size and shape, as using an incorrect belt can cause further issues.

Failed Motor

The motor is responsible for turning the belt and, in turn, the brush bar. If the motor fails or has failed, it may cause the brush bar to spin and stop. To fix this issue, you will need to replace the motor. This can be a more complex repair, as it involves disassembling your Dyson and removing the old motor. You will then need to locate a replacement motor and install it in your Dyson. This job may be best left to a professional, as it requires some technical expertise and specialized tools.

Damaged Battery

If your Dyson vacuum is cordless such as a Dyson V6, V8, or V11, a damaged battery could be why the brush bar is spinning and then stopping. If the battery is not functioning correctly, it may not be able to provide the necessary power to the vacuum, causing the brush bar to stop spinning.

To fix this issue, you will need to replace the battery. If you are comfortable with electrical repairs, you can try to do this by purchasing a new battery and following the manufacturer’s instructions for replacing it. Alternatively, you can take the vacuum to a professional repair shop for assistance. It’s worth noting that some Dyson cordless vacuums have non-replaceable batteries, so you will need to purchase a new vacuum.


Overall, understanding the causes behind why your Dyson brush bar spins then stops is essential to properly fix the issue and get your vacuum working correctly again. Whether the issue is caused by a stuck brush bar, a blocked wand or bin inlet, a clogged brush bar, or circuitry problems, it is crucial to diagnose the problem and take the appropriate steps to fix it.
