Amazon Echo Keeps Restarting — Fix Guide

What Does This Error Mean?

An Amazon Echo stuck in a restart loop is almost always caused by a faulty or underpowered power adapter. Use only the original Amazon power adapter — third-party adapters often do not provide enough power and cause continuous reboots.

Affected Models

Amazon Echo (all generations)
Echo Dot (all generations)
Echo Plus
Echo Studio

Common Causes

Underpowered third-party power adapter
Faulty or damaged power cable
Corrupt firmware update stuck mid-install
Hardware fault on the main board
Echo connected to a USB port instead of a wall outlet

How to Fix It

Ensure you are using the original Amazon power adapter that came with the device.

The Echo requires specific wattage. Third-party adapters, even if they fit the port, often deliver insufficient power and cause continuous reboots.
Plug the adapter directly into a wall outlet — not a power strip or USB hub.

Power strips and USB hubs often deliver lower voltage under load. A direct wall connection eliminates power delivery as a variable.
Try a different wall outlet to rule out a faulty circuit.

A faulty outlet or one on a circuit with heavy loads can cause insufficient power delivery to the Echo.
If restarting persists, perform a factory reset by holding the reset button for 25 seconds.

A factory reset clears any corrupt firmware state. You will need to set up the device again in the Alexa app, but this resolves software-caused reboot loops.

When to Call a Professional

If the Echo restarts every 1-2 minutes even with the original Amazon power adapter plugged directly into a wall outlet, the main board has a hardware fault. Contact Amazon support for a replacement.

Frequently Asked Questions

Why did my Echo suddenly start restarting after working fine for months?

A firmware update that failed mid-install is a common cause of sudden reboot loops in previously working units. A factory reset (hold reset button 25 seconds) clears the corrupt update state.

Can faulty Wi-Fi cause Echo to restart?

Occasionally — an Echo that cannot connect to Wi-Fi may restart to retry, especially if Alexa services cannot be reached during startup. Test with the Echo near your router to rule out Wi-Fi as the cause.
