Hi @TommyG,
Welcome to the Dyson Community, and thanks for letting us know about this.
To resolve this, in the first instance we’d recommend power-cycling your Dyson purifier fan:
We’d also suggest deleting and reinstalling your MyDyson app, and if your machine isn’t already set up to receive automatic software updates, it’s a good idea to enable this to make sure it’s always running on the latest available software.
If you continue to have issues after trying all of these steps, please speak directly with our Dyson Customer Care experts in your region for some further support. You can visit Dyson.com and click the round purple button to launch the Dyson Digital Assistant. Then click the agent icon in the bottom left corner of the chat window to start a conversation with our Customer Care team.
Hope this helps!
I know how to fix it, (classic turning it on and off again)
however I have two problems with this.
1/ the plug is behind the bookcase, so I have to do some moving of furniture to do it. So it takes time to do.
2/ I think for the price the SW should check the time and correct itself and not really on its power on state. In a general power cut, one does not expect the time to be correct when the router and everything else Is powering up. It’s systematic
I already contact Japan support, but they just repeated several times I should send the unit in and pay roughly 200 dollars for the privilege.
