Dyson V6 Flashing A Red Light (Ultimate Troubleshooting Guide)

Dyson vacuums are known for their durability and high quality, and the v6 is no exception. Dyson v6 cordless vacuums allow you the luxury of vacuuming your entire home without having to consistently move your cord to each new room.

However, sometimes vacuums malfunction and do not work properly or do funny things they probably shouldn’t do. When this happens, these vacuums tend to flash a light to signal what’s wrong. So, why is my Dyson v6 flashing red light? Keep reading to find out!

Why Is My Dyson v6 Flashing A Red Light?

Dyson’s cordless vacuum is a fan favorite and loved by many! But like all technology, these vacuums need maintenance to run properly.

There are a few different things you can troubleshoot to see if you can locate the source of the problem. Here are the most common troubleshooting tips for when your Dyson v6 vacuum is flashing red light:

1. Reset Your Battery

This may be obvious, but make sure your battery is fully charged before taking any more action. We sometimes forget to look at the things that are the simplest to fix. The flashing red light could indicate a critically low battery.

If your light flashes even when the battery is fully charged, there may be other battery issues to explore before moving on to something else. The next step to try is resetting your battery. This is fast and easy and may solve your issues!

To reset your battery, you will want to unplug the charger. Wait for a few seconds, then plug the charger back into the power source. Now, connect your vacuum to the charge and press the power button. Hold the power button down for 20 seconds.

This will reset your battery! Now, try charging your battery for the recommended charging time, and try to start your Dyson vacuum. If the problem persists, it is time to try something else.

2. It Needs A Battery Replacement

If resetting the battery didn’t work, it may be time for a new battery pack! Dyson batteries usually last around two years, so if it has been beyond this, it is likely your issue. However, there are instances where your battery could be faulty and go bad before the two years is up!

To change the vacuum’s battery, start by removing the rubbish canister. You can go ahead and empty it so it is cleaned out when you put it back; next, unscrew the screw at the top of the handle and the screw at the bottom of the handle using a flathead screwdriver.

If you do not have a screwdriver, a coin may suffice. Next, clean the area around the battery with a clean, dry cloth to ensure that no dust or debris ends up under your new battery and causes issues.

Now, just remove your old Dyson vacuum battery and replace it with a new one. Make sure you consult your user manual to ensure you get the right size battery for your vacuum model.

Now, replace the handle and rubbish canister and dispose of the old battery. Your vacuum should run perfectly fine now. However, if it doesn’t, there are a few other things you can try before calling it a day.

3. You Need To Change The Filter

Another cause of a Dyson flashing red light is its lack of suction power. One of the most common reasons your Dyson v6 loses suction is a clogged filter. Over time, dirt and debris build up on your filter, preventing it from functioning properly. To fix this, you need to either clean the filter or replace it entirely!

Luckily, the filter is extremely easy to access. It fits directly inside the cyclone located at the top of the vacuum. You will be able to pull the filter now out of the cyclone by simply grabbing hold of the level, twisting, and pulling up.

If you want to try cleaning it before replacing it entirely, you can do this by removing any excess dirt and debris, then running it under water until the water runs clean. Now, simply wring out any excess water and let it air dry for about a day.

Once it’s dry, pop it back into the cyclone, and you are ready to get back to cleaning! You should clean your filter at least once a month to ensure your Dyson vacuum stays in tip-top shape.

4. Issues With The Brush Bar

Another common issue with vacuums, and what could be the culprit behind the flashing red light, is issues with the brush bar. Check first to see if the brushbar is jammed or clogged!

When hair and other debris get caught on the brush bar, it prevents it from rotating properly, eventually preventing your vacuum from running the way it should.

To eliminate this issue, you will want to remove any hair getting in the way of the brush bar rotating the way it should. The best way is to use scissors to cut the hair, so you can easily pull it away from the brush bar. You should be able to rotate the brush bar easily now.

If your brush bar isn’t clogged and is rotating fully, it may be that it is too loose. To fix this, simply tighten the fasteners at each end of the brushbar.

5. Damaged Or Faulty Components

If the red light flashes less than 12 times, it could signal that one or more of the components, such as the motor, are damaged, and you need to call for a repair. This is most likely due to a manufacturer problem and less likely a user error.

6. It Needs To Be Replaced

Sometimes, there is nothing you can do except get a replacement. Before you invest in a new Dyson v6 cordless vacuum, make sure you call support to see if your vacuum may be covered under warranty.

Dyson vacuums usually have a 1-2-year warranty automatically, but you may have purchased an additional warranty when you purchased the vacuum. It’sis definitely worth it to check!

Common Problems With Other Lights

Along with a red blinking light, there are also other colored lights you should be aware of that will blink or flash to signal an issue.

1. Flashing Blue light

The most common reason for a flashing blue light on a Dyson vacuum cleaner is related to the vacuum’s battery getting low. If you see a flashing blue light, this is a warning that your battery will need to be charged soon.

2. Flashing Amber Light

If you see a flashing amber light, this could indicate your vacuum is either running too hot or too cold. If it is running too hot, this could be extremely dangerous, so make sure to turn off your vacuum immediately and call support for further action.

In contrast, if it is running too cold, your machine is not getting enough power. This is likely a temporary fault but will require an examination to find out what in your vacuum is the cause of it not getting enough power.

3. Solid Blue Light

If you see a solid blue light, this is perfectly normal and just means your battery is charging the way it should. If the solid blue light changes to red or doesn’t show up at all when hooked to the charger, this means that your battery isn’t charging, and you need to take action.


If your Dyson v6 cordless vacuum is flashing red light, there are a few different reasons this could be. One of the most common reasons for this is problems with the battery, such as it being critically low or needing to be replaced.

However, sometimes it could be as simple as a dirty filter or your brushes needing cleaning. Keep troubleshooting until you figure out what is wrong with your vacuum.
