Dyson Purifier Humidify & Cool Formaldehyde PH04 humidifier not working after deep clean cycle

U

Hi all, so I bought my dyson in may and just 2 weeks ago i did the deep clean cycle, after that its no longer working with a triangle alert sign on the screen with not turning off. I have tried every troubleshooting tips and trick with no luck. Before the deep cycle, the screen only showed green horizontal line and i thought it was in sleep mode so it didint show the full display but i guess i was wrong. The screen was malfunctioning too. 
 

As i dont have a dyson store in my country, and i biught from another country, i would like to fix it and use it. Please help!!!

@uyanga308Thanks for your post. The Triangle/! usually indicates some kind of unresolved electronic or mechanical issue. I’d suspect this is the case if you’re using the Dyson in another country with a different voltage standard.


Also, try using this machine in another room and not on a power strip.

Hi all, 

I have fixed the issue by returning the Dyson as the service center at Dyson couldn’t fix the issue themselves so they have changed it with a new one. And the one didn’t have any problems even after the deep cycle. So I think mine was defective.
