Hello @David.Roberts,
We’re sorry to learn you’ve encountered an issue with the display on your Purifier Hot+Cold Formaldehyde. It’s a bit disheartening to hear that your response time while using WhatsApp for support was slow.
For assistance with each of these alerts, simply click on our Guides and manuals link, select your machine from the list, click on the ‘Troubleshooting’ option and then select ‘Display showing an alert’.
The ‘Display showing an alert’ screen provides an overview of all these different alert types, their image and description, along with an in-depth step by step process to rectify the alert.
If you are still experiencing issues, we would encourage you to call the Dyson Helpline to speak with our experts directly. You can find their number in the ‘Contact us’ section of the page.
We hope this helps!
