Hi @Benny,

This it often simple to resolve. Please try the checks below:

• Unplug your machine and ensure it’s disconnected from the power supply for at least 10 minutes.
• Ensure you’re not using an extension cord or power strip. Your Dyson fan heater should only be used when plugged directly into a wall socket.
• Plug your machine back into the wall socket and retest. It’s also a good idea to test from a different wall socket, to ensure the issue doesn't lie with the socket itself.

This usually resolves things. If not, please visit Dyson.com and click Support to get in touch with the right Dyson Customer Care team for your region for further assistance.
