Knowing how to factory reset the Echo Dot can help you in case you are facing issues with your device. Performing a complete factory reset on the Echo Dot will delete all your data, settings, and Wi-Fi, and the device will be as it was when first purchased. The easiest way is to use the physical buttons on the Dot: for many generations, it was done by pressing and holding the Microphone Off + Volume Down for about 20 seconds to get a reset; the very latest models have the Action button that you hold for about 25 seconds. As soon as the light ring is spinning and the device is in the setup mode, you will have to reconnect it through the Alexa app.
