The belt is broken that spins the brush. Button is warning you that something is wrong.

They may have picked up something really disgusting and retained it. You will have to strip them completely and throw away the bag (if there is one), then go to work with pine oil (or similar heavy-duty cleaner) to scrub the entire intake path clean. Be sure everything is dry before reassembling.

Thanks for making contact and I'm sorry you're having difficulty.

I would suggest that this is a blockage of some kind as the pulsating is caused by a lack of airflow (the motor is protecting itself by pulsating and then ultimately cutting out).

I would recommend looking at the following video which will take you through a methodical way of checking this. The model in the video is a DC59 but applies to most cordless models:

Furthermore, I would check the bin inlet to make sure that the one-way door/flap is not jammed as this also can cause the problem.

If you continue to have difficulty, please give the Dyson Helpline a call on 1-866-693-9766 (US), 1-877-397-6622 (CA), 0800 298 0298 (UK). Our experts will be happy to talk you through some further diagnostic checks when you have your machine easily to hand.

Best wishes

Look to see if it has a switch on it that says floor /carpet. as it will raise the head enough for more clearance under it.Don't allow it to keep slipping, it will burn up the rubber band that drives the brush.
