Hi @tamih thanks for posting a question.
@BarryM has offered some great advice here. He’s covered all the areas the community support and Knowledge Base section would indicate. Whilst running a deep clean isn’t something we expect owners to do as regularly as weekly, in the event there is a blockage that could be causing an issue, this is usually a great place to start. Great to read you’ve done one recently.
I’d suggest running through some further checks online. These are designed to be straightforward and could help to highlight why this is happening. You’ll need your machines to hand to do this.
The best place to view this in the USA market is on our online support guide, which you can find here: https://www.dyson.com/support/air-treatment/purifier-humidifiers. Please select your machine from the list and follow the on-screen instructions.
Should you still have a concern after running through these checks, 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’.
Thanks,
Stuart
