Say the wake word and watch the ring, don’t listen for a reply
The light ring reports what the device is doing, and each colour is documented. Solid red means the microphone button has been pressed and Alexa is not listening at all. Orange means it is in setup mode or trying to reach the internet. A brief purple flash after a request means Do Not Disturb is on. A blue ring with a cyan segment means it heard you perfectly and the failure is further down the line. Those are four different faults, and the ring tells you which one you have before you touch anything.
Applies to: Echo, Echo Dot, Echo Pop, Echo Show, Echo Studio and Echo Spot. Ring colours are consistent across the speaker range; Echo Show devices add on-screen indicators, and Echo Buds and Echo Frames have their own separate troubleshooting.
What does the ring do when you speak?
“Alexa isn’t responding” covers a device that cannot hear you, one that is not on the network, one that is deliberately staying quiet, and one that hears and understands but cannot carry out the request. They feel identical from across the room and have nothing in common as fixes. The ring separates them in one attempt, so start by saying the wake word and watching rather than listening.

Look past the device1. The ring is a documented code — read it first
Amazon publishes what each colour means, and the list turns guesswork into a decision. A blue ring with a cyan segment means Alexa is listening, and it glimmers briefly while your request is processed. Slowly spinning teal and blue means the device is starting up. A slow yellow pulse means there is a message, a notification, or a reminder you missed — not a fault at all. White shows the volume level while you adjust it. Green pulsing means an incoming call, and spinning green means an active call or Drop In.
The three that matter for an unresponsive device are red, orange and purple, and each has its own section below. Say the wake word once, watch the ring, and note what it does. A device that produces no light whatsoever is a different case again — check that it is using the power adapter that came with it, since Amazon calls this out specifically and an underpowered third-party adapter causes a device that boots and then dies under load.
Note whether the ring responds at all, because that single observation splits the problem. A ring that lights when you speak proves the microphones work, the device is powered, and it recognises the wake word. Everything after that is network, account or service. A ring that never reacts to your voice means it is not hearing you, which is a much narrower set of causes.
A slow yellow pulse is the most commonly misread state. It is not an error — it means there is a waiting message or a missed reminder. Say “Alexa, what are my notifications?” and it clears.
2. Solid red: the microphone is switched off
This is the single most common cause and the easiest to miss. Amazon's description is unambiguous: a solid red light shows when the microphone on/off button has been pressed, the microphone is disconnected, and Alexa is not listening. The device is otherwise perfectly healthy — it is on the network, signed in, and will play music if you use the app — it simply cannot hear you.
Press the microphone button on the top of the device to switch it back on, and the red ring should clear immediately. The button is easy to catch when moving a device, dusting a shelf, or picking it up, and on the smaller Echo Dot it sits close enough to the volume buttons to be pressed by accident.
Worth knowing: on Echo devices the microphone switch is a hardware disconnect rather than a software setting, which is why no voice command can undo it and why asking Alexa to turn the microphone back on cannot work. You have to press the button. That design is deliberate and it is also why a red ring is a completely reliable diagnosis rather than a symptom needing interpretation.
3. Orange: it isn’t on the network
Amazon documents orange as the device being in setup mode, ready for setup, or trying to connect to the internet. If your device sits there spinning orange, it has lost the network and is trying to get back — and until it does, nothing that depends on the cloud will work, which is almost everything Alexa does.
Start with the router rather than the Echo. Confirm other devices in the same room have working internet, then restart the router and give it a couple of minutes to come fully back before checking the Echo again. Amazon's own first steps are to check for an active internet connection, unplug the device and plug it back in, and double-check Wi-Fi connectivity — in that order, because a device that has been retrying a dead network for hours often needs the power cycle to try again promptly.
If the network is healthy and the device still cannot join it, the stored credentials are the suspect — a router replacement, an ISP change, or a new Wi-Fi password all leave the Echo trying to reach a network that no longer exists under that name. Re-run setup from the Alexa app to hand it the current details. Purple during initial setup specifically means Wi-Fi trouble, so if you see purple while re-running setup rather than after a request, treat it as a network failure rather than Do Not Disturb.
Many Echo devices are 2.4 GHz-friendly and sit far from the router. If the device joins when carried next to the router and fails in its usual spot, that is signal strength, and no amount of resetting will change it.
4. Purple: it heard you and chose to stay quiet
A brief purple flash after a request means Do Not Disturb is switched on. The device is fully working — it heard the wake word, processed the request, and suppressed the spoken response and any notification. People turn this on for a night and forget, and the result reads convincingly as a broken device that has stopped answering.
It is worth checking specifically because it also explains the related complaints that bring people here: alarms and timers behaving oddly, reminders not being announced, and Drop In or announcements not coming through. Turn it off in the Alexa app under the device's settings, or say the request to disable it, and watch for the purple flash to stop.
Check any schedule too. Do Not Disturb can be set to switch on automatically during set hours, which produces a device that works perfectly during the day and appears dead every evening — a pattern that looks like a hardware fault developing rather than a setting doing exactly what it was told.
5. When it hears you and still does nothing
A normal blue-and-cyan ring means the device did its job. It heard the wake word, captured the request and sent it, so the microphones, the network and the wake word detection are all fine. What fails next is either the request itself or the thing you asked it to control, and that is a different investigation.
If the failing requests are all about smart home devices — lights, plugs, thermostats — the Echo is a messenger, not the problem. Amazon has separate guidance for smart home devices not working with Alexa, and the usual causes are the device itself being offline, its account link having expired, or the device having been renamed so the phrase no longer matches. Test by controlling the same device from its own manufacturer app: if that fails too, the Echo was never involved.
If it mishears you rather than failing outright, treat it as an acoustic problem. Amazon's guidance is to move the device away from walls, other speakers and background noise so that Alexa can hear you. A device pushed against a wall, behind a TV, or next to a noisy appliance genuinely does misrecognise more, and moving it a foot into the open is a real fix rather than a platitude.
6. Restart, reset, and what to tell support
Work up in order of cost. A power cycle — unplug the device, wait, plug it back in — is Amazon's own step and clears most transient states. Only when that fails repeatedly is a factory reset warranted, and it is genuinely destructive: it erases your personal information and every device and smart home connection on that Echo, so you will set it up again from scratch.
The reset combination is the same on the common models: on Echo 3rd and 4th generation, and on Echo Dot 2nd through 5th generation, press and hold the microphone off button and the volume down button together for 20 seconds, then wait for the light ring to turn off and back on again. Hold the full twenty seconds — this is another case where letting go early makes a working procedure look broken.
When you contact support, lead with the ring colour, because Amazon's own documentation is organised around it. Tell them what the ring does when you say the wake word, whether the device is on the supplied power adapter, whether other devices on the same Wi-Fi have internet, whether Do Not Disturb is off, and whether the failing requests are all smart home commands. Those five answers separate a muted microphone from a network fault from a device that is working perfectly and being asked to control something that is not.
Echo 3rd / 4th generation
Hold the microphone off and volume down buttons together for 20 seconds, until the ring turns off and on again.
Echo Dot (2nd–5th gen)
Hold the volume down and microphone off buttons together for 20 seconds, until the ring turns off and on again.
Frequently asked questions
Why is Alexa not responding?
Say the wake word and watch the light ring rather than listening for a reply. Solid red means the microphone button has been pressed and Alexa cannot hear you at all. Orange means it is in setup mode or cannot reach the internet. A brief purple flash means Do Not Disturb is on. A normal blue ring means it heard you fine and the failure is elsewhere.
Why is my Echo showing a red light?
The microphone is switched off — Amazon's description is that a solid red light shows when the microphone on/off button has been pressed and Alexa is not listening. Press that button on top of the device to restore it. It's a hardware disconnect rather than a software setting, which is why no voice command can undo it and why the diagnosis is completely reliable.
What does an orange light on my Echo mean?
It's in setup mode or trying to connect to the internet. Check that other devices on the same Wi-Fi have working internet, restart the router and let it come fully back, then unplug the Echo and plug it in again. If the network is fine and it still won't join, its stored Wi-Fi details are probably stale after a router, password or ISP change — re-run setup in the Alexa app.
Why does my Echo flash purple?
A brief purple flash after a request means Do Not Disturb is on — the device heard you and deliberately suppressed the response. It also explains alarms, reminders and announcements not coming through. Check whether it's on a schedule, which produces a device that works all day and seems dead every evening. Purple during initial setup means something different: a Wi-Fi problem.
Alexa hears me but won’t control my lights. Why?
A normal blue ring means the Echo did its job, so the fault is the smart home device or its account link — commonly the device being offline, an expired link, or the device having been renamed so your phrase no longer matches. Test by controlling it from its own manufacturer app: if that fails too, the Echo was never part of the problem.
How do I factory reset an Echo?
On Echo 3rd and 4th generation and Echo Dot 2nd–5th generation, hold the microphone off and volume down buttons together for 20 seconds until the ring turns off and back on. Hold the full twenty seconds. Note this erases your personal information and every device and smart home connection on that Echo, so try a plain power cycle first.
