New PH03, deep clean needed immediately? | Dyson Community
Skip to main content

Good morning everyone, and Merry Christmas!

I just unboxed a brand new PH03, shipped from Dyson, and set it up in Auto mode (fan and humidification). Within a few seconds, the on unit display requests a deep clean and the second button glows orange.

I looked in the user manual and the icon I’m seeing on the display suggests a Pump Rotor Failure.

I started a deep clean (suspicious that this is not the real issue) and now the on board counter display stopped counting down then it got to 59:50.

I suspect that this unit is faulty, can anyone confirm?

I can’t reach Dyson Support as it’s Christmas Day.

Afternoon @MartinB 

Merry Christmas and welcome to the community. 

Doesn't sound like your had a great experience. I’ve not got a Humidifier myself but I’ve seen a few post in the last couple of weeks with people querying pump issues. It might be worth searching the community homepage for keywords.

This article might also help.. 

Good luck. 


Thanks all, tech support determined that it’s an OOB (Out Of Box) faulty and has been returned.
