Dyson Blinking Blue: 5 Easy Ways To Fix It Forever Now

Are you trying to figure out why your Dyson is blinking blue and how to fix it? Chances are, you’re not alone, as many Dyson users experience the same issue.

This common issue can indicate anything from clogged filters and blocked hoses to faulty parts or user errors.

Whether your machine has been affected by pets shedding in your home or mishandling during the cleaning process, this guide will provide some easy fixes for when your Dyson starts blinking blue. So you don’t lose all hope of getting it working again and keeping things tidy around the house.

Why is your Dyson Blinking Blue?

Troubleshooting is the most important part of repairing your Dyson, regardless of the issue. If you don’t know why your Dyson is blinking blue, here are some of the most probable causes.

1. Clogged Filters

One of the most common reasons why your Dyson might be blinking blue are clogged filters. Accumulated dust in the filters can cause them to become clogged and prevent air from flowing properly through your Dyson.

The role of the filters is to capture and eliminate dust from the air, which is then cycled back into your room. As long as they’re clogged, the filters will cause your Dyson to blink blue.

2. Empty Battery

Dyson’s blinking blue light indicates that its battery is empty. This can happen for a number of reasons, including improper use or excessive wear and tear on your Dyson device.

3. Full Dust Container

One of the common reasons for a flashing light on your Dyson is a full dust container. A full dust container will also result in your machine being less effective at cleaning.

Many Dyson models are equipped with a handy indicator light to help determine when your vacuum needs to be emptied.

If the light begins to flash blue, this means that there is a full dust container. Note that this only applies to upright models – bagless models will have a full bin light instead of a blue light.

4. Attachments aren’t Properly Connected

Yet another possibility is that the Dyson attachments haven’t been connected properly. This will cause the unit to blink blue from the power button. The attachments will also not be able to work properly.

5. Blocked Airway

It is also possible that the Dyson airway is blocked. Many things could cause an obstruction in the airway of the device, including a piece of debris, a cloth or other foreign object inside the airway, or even an insect.

Either way, an obstruction in the airway could cause the light to flash blue as well. Another possible explanation for this issue is that some kind of blockage has developed in one or more of the filters within your Dyson.

The filters inside a vacuum cleaner are designed to trap dust, dirt, and other types of debris as they move through the air intake area while the unit is in operation. If any of these filters become clogged or dirty, it can cause airflow issues that may result in this flashing blue light.

If you have attempted to clean the filters inside your Dyson unit and still see the blue flashing light, it may be a sign that you need to have the unit professionally serviced by an experienced technician.

A professional repair service can inspect your unit to determine exactly what is causing this issue, and make any necessary repairs or replacements so that the device will work correctly again.

How to Fix Dyson Blinking Blue

Luckily, most of the problems causing your Dyson to blink blue can be solved without having to wait on a professional. Here’s what you can do to solve the core issue and prevent your Dyson from blinking blue.

1. Clean the Dyson Filters

Cleaning the Dyson filters is a fairly simple task. Here are the steps to thoroughly clean any buildup and clogs that may have formed inside the vacuum filters:

  1. Remove the vacuum filters from the machine and check for visible clogs or buildup. If you notice any large clumps of dirt, hair, lint or other debris stuck in the filters, use a small brush to clean these areas gently.
  2. Once you are sure that all visible clogs and buildup have been removed, take a damp cloth or paper towel and wipe off the entire surface of the filters. This will help to remove any remaining residue that may be preventing airflow in your vacuum.
  3. Once you have cleaned and wiped the filters, allow them to dry completely before replacing them in your Dyson vacuum machine. This process should only take a few hours or overnight, depending on the humidity level of your environment.
  4. When you are ready to reinstall your Dyson filters in your vacuum machine, make sure that they are properly aligned with the grooves and slots in their designated areas. Then, push them firmly into place until you hear a click or snap indicating that they are secured.
  5. Once your filters are in place, turn on your vacuum and see if they have successfully cleared any clogs or buildup from the air path. If you notice a change in performance, such as less suction power or noise during use, this is an indication that further cleaning may be needed to get your machine back in good working order.

If you want to avoid clogs and buildup in your vacuum filters, it’s a good idea to clean them regularly, perhaps once a month or even more frequently if you notice any noticeable signs of buildup.

This will help keep your Dyson running at peak performance for longer and ensure that it stays free from contamination that can cause damage over time.

2. Charge your Dyson or Replace the Faulty Battery

Since the Dyson might be blinking blue due to an empty or faulty battery, you might have to charge it or replace the battery.

Here are a few steps to follow if your Dyson is blinking blue: 

  1. Check whether there’s an issue with the battery of your vacuum cleaner by unplugging the device and removing its batteries.
  2. Plug in your Dyson and wait for about 10 minutes, still without the batteries.
  3. If your Dyson is still blinking blue, plug in a different charger–perhaps one that you know works with other similar devices–and then try charging it again.
  4. If your vacuum cleaner’s battery has not been responding to any charge, you may need to replace it entirely. In this case, you can either order a new battery before purchasing your product or look for it at the local hardware store.
  5. If you’re sure that both the charger and your Dyson are functioning properly but still experiencing issues with charging, you may need to take it in for servicing.

3. Empty the Dust Container

In case the dust container of your Dyson is full,  you may experience a blinking blue light. In order to fix the issue, you need to empty the dust container and the filter of your vacuum cleaner.

To empty the dust container, unscrew it from the canister of your vacuum cleaner and simply press on the little area between the two parts of the container that keeps them together.

The bin should come out easily, allowing you to remove all of its contents. After cleaning the dust container and filter, put everything back in place and you will have your Dyson working as good as new.

4. Make sure that the Attachments are Properly Connected

Generally, if you notice that your Dyson is blinking blue, you should always check to see if any attachments are properly connected.

For example, the blinking light could indicate a loose connection if you don’t have the vacuum head attached or if the hose is detached.

If this doesn’t solve your problem, then it’s possible that something inside the appliance has become dislodged and may need to be recalibrated by a professional. With proper care, your Dyson should provide many years of use without issue.

5. Make sure that the Airway is Free of Blockages

It is possible that the blue light is signaling that there is a blockage in the airway of your Dyson vacuum.

The simple solution is to open the vacuum and check if any objects, such as hair or dust buildup, are blocking the airway.

Once these items have been removed, your Dyson vacuum should work correctly again. You can also try removing and reattaching the hose by holding down the button on top of it and pulling gently.
