Dyson Hair Dryer Stopped Working – Troubleshooting & Repairing

Dyson Supersonic is considered to be one of the best hair dryers on the shelves, but like anything in this world, even the most expensive hair dryer sometimes can stop working because of many reasons.

Sadly, it is pretty hard to diagnose and troubleshoot once your Dyson dryer stop working. So you might be interested in fixing these most common Dyson hair dryer problems before you turn to Dyson’s after-sales service.

1. Is The Filter Blocked?


If you are running into issues and need help to get your Dyson hair dryer work properly again, the most common issue might be caused by a clogged filter.

If you are seeing the lights of the dryer is flicking while the airflow is very weak, you might need to clean the filter by now. A blocked filter can affect the airflow and your blow dryer can only produce low-pressure, low-velocity air.

And a blocked filter can also cause louder noise and unpleasant dusty smell. We know Dyson hair dryer’s filter is located at the bottom of the handle. As time goes by, the dirt & residue can attach to the tiny holes of the dryer. If your hair dryer is getting noisier than usual, it can be a sign to clean up the filter thoroughly.

How to Clean the Dyson Hair Dryer Filter?

Basically, you should turn off your dryer and take off the filter, and then wide the dirt & lint off the mesh with a dry cloth.

And rotate the filter cage back into position, and turn on your dryer again.

If you’d like to learn how to clean your Dyson supersonic dryer in detail, please see the video below. Or, you can see our Dyson hair dryer cleaning tutorial and you can go to Dyson’s official website as well.

2. Check The ALCI Plug


If your Dyson dryer is not working and its lights are not functioning at all, the plug sometimes can be the cause.

When you accidentally touch the “test” button on the plug, the blow dryer will shut off immediately and you need to reset the ALCI plug to make it work.

To reset the ALCI, turn off and unplug your hair dryer first. And press the ‘reset button’.

You can also try to use another plug socket to diagnose the issue, sometimes the problem is not caused by the dryer itself. Also, you are not supposed to use a US version Dyson blow dryer in other countries as Dyson Supersonic is not a dual voltage blow dryer, and it will stop working once the voltage is not correct.

3. Contact Dyson Support

Unfortunately, according to Dyson official website, there is not much you do when a more complex problem occurs, so the most effective way is to consult Dyson support department.

Do not open and disassemble a Dyson Supersonic if you are not an expert because the inner structure of this hair dryer is very complicated. Once you open the dryer body, it is quite hard to put it back.

Feel free to call their customer center as 1-866-314-8881 if your Dyson hair dryer stopped working, and they will provide you with the most professional solutions. And if the hair dryer model that you own is Supersonic Professional edition, you can contact them at 1-866-861-2565.

  1. brand new Dyson hair dryer first time use switched it self off after less than a minute and then came back on an off again

      • Good Luck with that. I have a Dyson blow dryer which shut down completely. There was no flickering or notice of any kind. I have followed all the steps suggested by the company to to no avail. I contacted Dyson Customer Service and they said too bad, we will give you a 20 percent discount on a new product, They informed me that there is no Dyson Repair Center for hair dryers, only for vacuums. That is unacceptable. This is a very expensive product and I expected professional advice and direction, and replacement if necessary, I have received better service on a $29.00 hair dryer. I will be following up with my legislative contact who is working on a right to repair bill among other things. Very very disappointing! Shame on Dyson

    • I had this problem & even after cleaning the filter it kept happening. I realized it was occurring when my hand was on top of the lower part of the dryer where the filter is, thus blocking the air flow. Now that I’m aware, I try to avoid putting my hand there but sometimes I forget. It then has to stay off for a while so I use a back up blower. Bad design for an expensive product!

  2. My Dyson hairdryer is over heating. I have cleaned the filter. The lights stay on but it cuts off and won’t come on again until it has cooled down.
    Purchased from Boots in December 2018

  3. My Dyson Supersonic hair dryer stopped working after about 3 and half months. It is blinking 3 white lights, and the blowing would not stay on after switched on. I checked the filter, it was not very dirty. Now, I think I need to contact Dyson Customer Support about this device premature failure. This Dyson Supersonic hairdryer was purchased from Dyson website directly.

  4. I’m also very disappointed with this brand, the only rake in money, but provide no customer service. Had an issue with their vacuum, now with hair dryer… that’s $1000.00 down the drain in like year and a half… oh well next time its back toChinese products, where I can fill the land vs. with just one dyson…

  5. After having my 400.00 for a year and a half it just stopped. Can I get it repared or replaced. Does dyson stand behind their products?

    Have had my dyson hairdryer for 2 years now and has been overheating for about a year. I have to wait for it to cool down before using again so takes ages to dry my long hair . I receive this hairdryer as a Christmas present and am so so disappointed with this product . I have a large family and they keep asking wether it’s worth purchasing and I say no I wouldn’t pay the money for it myself . So there you go dyson your sale numbers will be low this year .

  7. I got my days on supper sonic from the bay i asked them what do i do it just stoped working she told me there in no repair on the dryers we will give you 20% off on your next purchase. I was very upset i payed 600.00 hundred dollers for 4 years now spend another 450.00 thats crazy. I think they should fix this item or stay away from hair dryers tottaly

  8. Ours just quit. Out of warranty. Have a Dydon vacuum that’s a mess really to use. Picking lint out of it every time you use. Done with the company.

  9. You can wash the filters in cold water until it runs clear (without using any detergent or soap). While you should squeeze and twist the long pre-filters to dislodge any dirt inside, you can simply rinse out the post-filter, taking care not to damage the pleats inside

  10. I am hugely disappointed with mine too stopped working and no interest what so ever when I called the dyson helpine as above I was also offered 20% discount on a replacement WHATA RIP OFF sounds like a common fault we should all take this further …… rip off Britain on TV

  11. My dyson supersonic keeps cutting out no lights flashing. Phoned customer service today. They put fault into the system and I was told it needs replacing and as I purchased it in 2017 out of guarantee and so I could have a refurbished one for £210 plus 2 year guarantee. When I said it was not acceptable after 3 years she checked to see if I could have a refurbished one for £99 plus 1 year guarantee but that offer is no longer available. I shall carry on using my BaByliss which I have had for nearly 10 years and cost about £30. Dyson should be ashamed of themselves. Probably so many prematurely breaking they are too mean to replace them. Website says could last 10 years but clearly quality not good enough too.

  12. My Dyson Supersonic just keeps cutting out – I reckon its a loose power connection where the cord enters the appliance as if I wiggle that area a bit the machine comes on again (for a bit). Dyson say they don’t repair dryers and as its out of warranty (but still looks sparkling new) they said if I paid £210 I could exchange it.
    This is ridiculous, first from a customer service point of view – these things are NOT cheap. And secondly how the hell is that environmentally friendly?
    How can we call Dyson out on this?

  13. My Dyson hair dryer stopped working after 2 years and on average used it about once a week. Not what I expected after investing over $500 CAD. Not impressed with customer support either, thanks for the 20% discount towards another Dyson product , however I won’t be spending a penny on anymore Dyson products and I’ll be spreading the word on my experience.
