How to factory reset a Sonos Play 1

I’m selling a load of old gadgets and the first thing I had to do was reset my Sonos Play 1.

Here’s how to reset

1. Turn off your Sonos at the wall
2. Hold down Play/Pause and Volume Up
3. Turn on your Sonos at the wall
4. Keep holding down until you see a red and white flashing light
5. Let go of the buttons
6. Wait until you see the light change to a flashing green and white light

It’s now reset.
