Hi @Pauldt, thanks for your post. If you are seeing any blue/red flashing lights, with no power, I’d recommend visiting our online support guide, which you can find here: https://www.dyson.com/support. Here, you’ll be able to run through a few quick and easy troubleshooting checks to help work out why this is happening. If it can’t solve it, you’ll be directed through to contacting one of our customer service representative for further help.
