The Dyson V8 vacuum cleaner is not charging? Fix

The Dyson V8 is a powerful and versatile cordless vacuum cleaner that provides powerful suction to clean the entire house and eliminate long and pet hair.

It has an advanced filtration system that captures dust and seals in up to 99.99% of microscopic particles as small as 0.3 microns.

But since it is a cordless vacuum cleaner, charging requires up to 40 minutes of non-stop cleaning. However, sometimes the device fails to charge despite connecting it to a power outlet for hours.

When you power the Dyson V8, it should operate as the manufacturer recommended. However, if you see a flashing blue light on the indicator, you must charge its battery.

Therefore, you have to hook it up to a charging cable or docking station. The vacuum cleaner will charge fully after five hours.

However, a problem requires your attention if the Dyson V8 does not charge after five hours.

Why is your Dyson V8 vacuum not charging?

Generally, you will know that the Dyson V8 is not charging when the blue and red light flashes continually.

Several things can explain why this is happening:

  • First, you have not plugged the device into the charging cable and power outlet.
  • You have a damaged charging cable.
  • The fuse is not working.
  • Something is blocking the vacuum cleaner’s airway.

The battery can also fail to charge and show no light if the battery is no longer working or is damaged.

Luckily, some issues that result in the Dyson V8 battery not charging can be easy to troubleshoot.

How to troubleshoot a Dyson V8 battery that is not charging

If your Dyson V8 vacuum cleaner is not charging, try the following troubleshooting steps:

1. Check to ensure that the machine’s airway is not blocked

The airway on the Dyson V8 requires proper airflow. Therefore, a blocked airflow will cut the device out to ensure safety. Check whether there are blockages in the hose, wand, and dust canister.

Also, it is helpful to clean the filters regularly to prevent airway blockage since it can shut the entire vacuum down. If not checked, the issues could worsen and damage the filter and the battery.

2. Check if you have plugged in the device

You can determine why the battery is not charging by checking whether you have plugged the device into a power outlet or docking station.

If the cord is off, the vacuum will not charge. Also, ensure the socket works well because it may not produce enough power to charge the device.

3. Check for any damage on the battery casing

A cracked battery casing is one of the indicators that your vacuum cleaner has a damaged battery.

Therefore, charging it would be unnecessary because it requires replacement.

4. Check the fuse

The V8 cleaner comes with a fuse in the charger. If the fuse is not working, you will have to replace it. You can find the fuse inside the plug.

Consider removing it using a screwdriver and pop it out. Then, replace it with one that has the same amp rating as the old fuse.

How many years does a Dyson V8 battery last?

The Dyson V8 battery has a two-year guarantee. However, expect the cordless vacuum battery to last around four years.

Furthermore, since the device uses a lithium battery, performance issues and battery problems may not even last a year.

If the battery lasts more than four years, expect it to degrade slowly. When that happens, the Dyson V8 charge time and battery run time will decline significantly.

However, multiple factors determine the battery life of the Dyson V8, including quality of maintenance and storage.

Furthermore, battery life is not determined by the number of years it operates. Therefore, maintain the battery to maximize its life and run time.

How do I know if my Dyson V8 battery needs replacing?

You will know it is the right time to replace your Dyson V8 battery if the following things happen:

  • A reduced run time when the battery is not in MAX power mode.
  • The vacuum displays more than 12 flashing lights.
  • Third, the device is not turning on despite charging the battery for five hours.

If you notice any of the above, it is time to replace the battery.


There are several ways to troubleshoot a Dyson v8 vacuum cleaner that is not charging. For example, ensure you have plugged it into a charging port or docking station.

You should also check that the fuse is working well, the battery casing is not damaged, and the vacuum cleaner’s airway is not blocked.
