1. Unplug HomePod, wait 5 seconds, then plug it back in.
2. Wait 5 seconds, then touch your finger to the top of HomePod and hold it there.
3. The white spinning light will turn red. Keep your finger down. 
4. Siri will say that your HomePod is about to reset. When you hear three beeps, you can lift your finger.
