Hello @Trac69 

Thanks for posting a question to the wider community. Sorry that you are experiencing this with your Dyson v15.

When a machine pulsates (switching on and off), usually this is an indicator of a blockage, a filter that needs to be washed or a damaged filter.

As mentioned you already cleaned your filters and checked for blockages, I would then suggest you look into replacing your filters as there is definitely a restriction in air flow within your machine.

You can either place an order via or website or make contact with us directly and one of our Representatives will assist you with this.

If you need further support after this, please get in touch via our WhatsApp channel and one of our team will be happy to discuss the next steps. To do this, simply click on our Guides and manuals link, navigate to the ‘Contact us’ section of the page and select ‘Start a WhatsApp conversation’. 

I have also added a link for further insight on maintaining your Dyson over here
 

If there is any further support you require, don't hesitate to respond over here.

Regards,

I have tried a new filter still the same problem I have rang Dyson and they sending a new unit to try as no fault message comes up there’s a blockage 

Stick vacs are easy to troubleshoot if you know how, but can be expensive outside of the warranty. They either replace the battery, charger or main body. In the event they can’t solve it with one, they move onto the other. I’d say the fault is with the main body, the sensors are misdiagnosing an issue. Frustrating, as it means you can’t use it until they’ve replaced a part. 

Hi All.

Have the same problem with mine. Not even a year old and give me more head aches with this the past 2 weeks.

I Haved clean the fliters, even blown it clean with air. But still does the same..

Anything more i can check or do?

Thanks

Hi Jack,

Thank you for the reply, I will defnitly do this during the day.

Really appriciate your advice

I have the very same problem with my V15 and still waiting for a replacement for more than a month now.
2 replacement orders have been created meanwhile and automatically closed by the support team without any explanation.
​​​​​​​This is terrible customer support...

Its something to do with the main body, we have had 3 replacement bodies now (last one they told they will not replace) if you search online its a common issue. You spend all this money on a hoover that cant even last a year it seems. Goodluck on the replacement. It will happen again. Dyson really need to look into this issue, as now im left with a faulty hoover which i aint paying more money to fix. They always seem to go at the same time period. 6-8 months
