Dyson Airway Blocked: Solve and Prevent This in Future

When there is an airway blockage in a Dyson vacuum cleaner, the suction power reduces and therefore the vacuum cleaner stops functioning normally. Many Dyson users have faced this issue and some of them even reached out to me for help.

So, why does my Dyson show airway blocked message? If your Dyson vacuum is showing an airway blocked message, it is due to blockage in the air filter. This issue can easily be solved by changing the Dyson filter. You must change your Dyson filters every year to prevent this from happening again in the future.

I have personally faced an airway blocked issue with my Dyson vacuum and this doesn’t just reduce suction but sometimes you will feel that there is no suction at all.

If you use a handheld vacuum with a screen, you will see a message “Airway Blocked”. In this article, I am going to tell you how you can solve this easily and how you can prevent this in the future.

What are the reasons for the Dyson Airway Blockage?

There could be several reasons for the clogging of the air duct in a vacuum. However, it is always said that it depends upon what you are vacuuming and how you are handling your vacuum.

But several other reasons can cause blockage to your Dyson vacuum.

  • Not cleaning of Dyson filters regularly or once a month.
  • Dust container not being emptied.
  • Vacuuming sticky dirt.
  • Vacuuming large debris.
  • Using local or wrong Dyson parts.
  • Wrong connection of Dyson attachments.

You must always buy Dyson vacuum parts and attachments from Dyson. Sometimes, using a local attachment and parts causes more damage to the vacuum.

Many users have asked me what will happen if they don’t resolve this airway blockage problem? Will my Dyson stop working?

What will happen if I don’t resolve the Dyson Airway blocked message?

When there is a blockage in the air duct, the vacuum suction power reduces or there could be worst like no suction in a Dyson vacuum.

Therefore, you must resolve this issue as soon as possible to avoid further damage to your vacuum.

Here are some of the larger problems that a blocked airway can cause.

  • Reduction in suction power or no suction at all.
  • Reduction in vacuum cleaner performance.
  • Blockage prevents the motor from getting cooled resulting in serious issues for the motor.
  • Your vacuum can start to smell.
  • Increase in dust emissions, resulting in allergic reaction risk.

How can I know if my Dyson is clogged?

Reduced suction in a Dyson vacuum is caused due to several reasons and air blockage is one of those reasons. The low or reduction in suction can also be seen if your battery has gone old and need to be replaced. So, how to know there is a blockage in air duct?

If your Dyson air duct is blocked, you will see the following things.

  • If you are using newer models of Dyson vacuum-like Dyson V11, V12, and V15 series, an “Airway Blocked” message will appear on LCD screen.
  • The vacuum cleaner will stop sucking or reduce suction with low performance.
  • You wouldn’t be able to see through the vacuum rod.
  • Blue light will start flashing. (If blue light stays on, it is due to low battery)
  • Dyson will stop automatically. (This can also happen if the filter needs cleaning)

Remember to switch your Dyson Off and take out the cable from the power source as it can be dangerous to disassemble or look through the vacuum when the Dyson vacuum is switched on.

How to Resolve Dyson Airway Blockage?

Before you start to resolve the airway blocked issue, it is important to know where exactly the blockage is!

Go through the below steps to find out and solve the problem at home.

  • The first thing you have to do is to disassemble all parts and attachments.
  • Press the trigger button and hold it for 10-15 seconds.
    • If the blue light stops blinking, check for the blockages in Dyson parts and rods.
    • If the blue light keeps blinking, go to the next steps.
  • Check the dust container and remove the dirt present in the dust container.
  • Again, press the trigger button for 10-15 seconds, if the blue light stops blinking, the issue is resolved.
  • If the Dyson vacuum is still blinking blue, remove the dust container.
  • Shake the vacuum cleaner to remove the fine dust.
  • Mount the container back to the Dyson vacuum and attach the floor brush to the Dyson vacuum.
  • Now, press and hold the trigger for 10-15 seconds.
    • Blue light stopped flashing. The problem is Solved
    • Blue light is still flashing – Go to the next step
  • If the blue light is still blinking, there is an issue with your Dyson filter and it needs to be cleaned or you might need a new Dyson filter.

Remember to clean your Dyson filters regularly. Every Dyson series have its own filters and some series have 2 filters.

Tips To Prevent Dyson Blockage in Future

Now you know that finding Dyson Air Duct blockage is not that easy task and requires a lot of effort and time to find out where the blockage is!

Here are some smart tips that I use to prevent air blockage in my Dyson vacuum.

Maintain Your Dyson Vacuum

When it is said to maintain a Dyson vacuum, it means more than dust cleaning the Dyson dust container and Dyson filters. You must go through the below video on how to clean a Dyson vacuum.

Use Dyson Vacuum on Suitable Surfaces

You must use a Dyson vacuum on suitable surfaces. Using the vacuum on the sticky surface can cause dirt to stick inside the Dyson filters and other parts and attachments resulting in further issues to the vacuum.

Empty Dust Container regularly

Whenever you use the Dyson vacuum, you should clean the dust container. Yes, even if it’s not full. When the dust sits inside the container for a long time, it can stick inside and cause blockage.

Replace Parts That Are Prone To Wear

Parts like filters are supposed to be replaced regularly, once a year. So, Dyson filter replacement can be a good idea to prevent blockages.


When Dyson vacuum shows an airway Blockage message, it is due to blockage in parts and attachments of the vacuum cleaner. Maintaining the vacuum cleaner and cleaning Dyson filters once a month can prevent this from happening in the future.

Also, make sure to replace the old Dyson filter with a new filter once in 12 months.
