Discusses locations of the Echo Dot reset button on some models.
Echo Dot Reset Button On the Gen 1 Dot
Firstly, on the 1st generation Echo Dot, find this button on the under side (the bottom) of the unit. Specifically, the Amazon page Reset Your Amazon Echo or Echo Dot (1st Generation) says that the button on this version of the speaker is at its base. Then, see our post How to Reset Echo Dot 1st Generation to Factory Default for more details.
Echo Dot Reset Button: Gen 2 Dot
On the second generation Echo Dot, there is no separate button for resetting the speaker. Instead, the Mic Off and Volume Down (-) buttons on the top of the unit are pressed and held down at the same time to initiate a factory default reset. See these in the following picture. Finally, see our How to Reset Echo Dot 2nd Gen to Factory Default for more details on resetting this Dot Echo.
On the Gen 3 Dot
On the 3rd generation Echo Dot, again, we find no separate button for resetting. Rather, the Action button on the top of the unit also acts as the Reset button. See this button location in the following picture. At last, check our Reset Echo Dot 3rd Generation to Factory Default Settings post for more details.
