AM09 showing fault F3 when first turned on | Dyson Community

Bought a AM09 hot-cold today and is showing F3 on the front when plugged in for the first time, any suggestions on how to get her going 

Hi @Slimseamy,

Welcome to the Dyson Community!

The F3 fault code can usually be cleared with a hard reset. All you need to do is to unplug your machine from the power supply for 60 seconds, then plug it back in and test it. We’d also recommend trying another socket to see if the issue reoccurs.

This should resolve things completely, but if you do need further help after this our Customer Care team in your region will need to take some additional details. To reach them, visit Dyson.com and click Support.

Hope this helps!
