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

Check for clogs in the turbo head, wand and hose.

Some models have the beater bar driven by the airflow from the vacuum rather than a small motor. It takes a lot of suction to turn the brush roll. Make sure there are no restrictions which will reduce the airflow and suction. Replacing the filters may help if the vacuum motor still has adequate suction.

Hi there, it's Jack at Dyson.

Hi Paula, it's Jack at Dyson.

Like most Dyson vacuums, DC39 is engineered to shut itself down for protection if it starts to overheat. This will usually be due to a blockage, and the filter may also need a wash.

You should find the machine will reset itself after it's had at least three hours to cool down. But to prevent any damage to your vacuum, please give the filter a wash, and check for any blockages.

To check for any blockages in the floor tool, wand, hose or hose inlet, please follow the steps shown in our online Support guide: http://www.dyson.com/support/dc39/dc39-animal/diagnosis-root-menu/performance-flo-extension-tube-suction-check-dc39

DC39's filter should be washed once every three months in normal use, as shown in the video below. Use cold water without detergent, and allow up to 24 hours for the filter to dry completely before replacing it.

I'm confident this will resolve the issue, but if you'd like any further advice after you've given this a try please call our experts directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Hi Linda,

I am sorry to hear you are having difficulty with your DC39 brush bar. The brush bar on your machine is air driven. Generally, if the brush bar stops rotating it is due to an obstruction that is preventing air flow. Please visit the appropriate link below for step by step instructions on locating and removing a blockage from your machine.

We also recommend inspecting the brush bar to ensure it is free of any debris and washing your filters. If for any reason the recommended trouble shooting does not fully resolve the problem please contact our Helpline to speak with an expert.

I have the same problem with my DC39 Animal's brush bar. Im on my 3rd one in 9 months of ownership. The DC39 brush bar is driven pneumatically (there is no electric motor in the brush head) and switched on and off via a suction activated pneumatic ratchet within the brush head. The moving components are actuated by bellows. Ive found that the glue holding the bellows fails stopping the ratchet working intermittently at first and then completely as the bellows comes away completely. At first you can help the ratchet by tapping the brush head - the red ratchet ring can be seen to click round. This, in my opinion, is an inherent weakness of the DC39 design and cannot be easily repaired. The only solution is a new brush head. Luckily Ive got a 5 year warranty and at the current rate I will have got through about 20 brush heads !
