Hi
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: https://www.youtube.com/watch?v=fdnu4yk-5vI
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.
Unscrew this one screw to do it. wiggle the loose bit. until you can fit a flat head screwdriver into the gap the catch fits into . Dunt the bit out. Screw back into place. Push the catch in from the front until it clicks.
Hi there, it's Jack at Dyson.The filters in our handheld machines should be washed at least once a month using cold water without detergent. However, they should always be allowed to try completely before they're replaced, which may take at least 12 hours. It can help to place the filter somewhere warm - for example, by a radiator, or in an airing cupboard.Unfortunately, if you have used your machine with a wet filter in place, this is likely to have caused damage to the motor. Using your machine with a wet filter will also have voided the machine's 2-year guarantee.I would encourage you to get in touch with us directly so we can confirm which replacement parts you may need to get the machine running again. You can reach our customer Helpline on 0800 298 0298 (UK), or 1-866-693-9766 (US).Best wishes,JackDyson Online Customer Supporthttp://www.dyson.com
Odds are it's overheating and can't breathe. Check for clogs in the wands (they are very thin in diameter). They can also clog in the lower hose and/or the long hose you use for attachments. If all that is clear your filter could be clogged. But it definitely sounds like it's overheating.
Suction stops when there is either something blocking inside the hose or you vacuumed a sharp object that created a hole or tears in the hose or bottom transfer line.
You will need to look very carefully at the hose to see is something is jammed up also turn the unit over and look at the looping hoselike section to see if there is a tear or jam. if its a jam carefully remove the object. if its a tear you will need to get the part from Dyson to replace it. since the unit is new you can also send it in for repair. depending on whether the unit is new or refurbished you should have from 1-5 years.
