You need to charge a cordless vacuum cleaner regularly. If you don’t do this, you won’t be able to vacuum right away, which can be very annoying. It’s even more annoying when you think you’ve charged your vacuum cleaner, but in the end it turns out not to be the case.
It can happen that a Dyson no longer charges. This can have various causes: the battery may be worn out or the charging cable may be broken. In this article I will tell you why a Dyson vacuum cleaner no longer charges and how you can solve this.
Reasons why a Dyson vacuum cleaner no longer charges
While chances are your problem is a worn out battery, there could be other reasons as well. I list the most important reasons:
- The Dyson battery is not properly connected to the vacuum cleaner
- The battery of your Dyson vacuum cleaner is worn out
- You took the Dyson out of the charger too soon
- The charger or charging cable is defective
- The connection of the cable no longer works
How to recognize a Dyson that isn’t charging
There are several factors by which you can recognize that a Dyson no longer charges. For example, the light no longer lights up when you connect the Dyson vacuum cleaner to the power (after all, there is no battery power).
- The Dyson won’t turn on, even after charging for the minimum number of hours
- A red light will flash, indicating a worn-out battery
- The blue light does not come on when you charge the Dyson battery*
* If you have a newer Dyson with an LCD screen (for example, the Dyson V15 Detect), you will receive a message on the display when charging.
Solution: this way you can recharge the battery
If a Dyson vacuum cleaner stops charging, you can no longer use it. So it is very important to fix this problem as soon as possible.
First let’s rule out that the vacuum cleaner isn’t just running out of power. That is why it is smart to charge the Dyson for the minimum number of hours first. And yes, that may feel a bit hopeless, but this may prevent you from buying an extra battery for nothing.
View the minimum charging time per Dyson vacuum cleaner series below.
Dyson serie | Minimum charging time |
---|---|
Dyson V6 | 190 minutes |
Dyson V7 | 221 minutes |
Dyson V8 | 301 minutes |
Dyson V10 | 210 minutes |
Dyson V12 (Slim) | 280 minutes |
Dyson V15 Detect | 275 minutes |
Dyson Omni Glide | 208 minutes |
Dyson Micro 1.5kg | 237 minutes |
Have you charged the Dyson for at least the number of hours? Then you can refer to the following checklist to possibly identify the problem.
- Is there a red light blinking? Then there is a problem with the Dyson battery.
- No flashing red light? Check whether the Dyson does flash a blue light when you plug the charging cable into the Dyson.
- Is there no light at all? Then there may be a problem with the charging cable and/or charger. Check the cable for possible damage or defects.
- No visible defects on the charger? Then check whether the Dyson battery is properly connected to the vacuum cleaner. Remove the battery from the vacuum cleaner and reinsert it*
From experience I can say that in many cases the problem will lie with a defective battery. Replacing a Dyson battery for a new one is often the only solution. Although this entails additional costs, the replacement itself does not require any technical knowledge.
* Many people ask if you can reset a Dyson battery. It is not possible to reset a Dyson battery, but it can of course be smart to click the battery back into the vacuum cleaner.

New Dyson battery? Check these tips first!
Before you just buy a new Dyson battery, it is smart to read the tips below carefully. This way you may still have warranty on your battery.
- Check whether you still have warranty on the Dyson battery
- Always go for a battery from Dyson itself, universal batteries can damage your Dyson
- Check whether the battery is suitable for your Dyson vacuum cleaner (see the manual ‘Which Dyson do I have?‘ to find your serial number)
- Choose the right type of battery: do you have a battery that you click in or a battery with screws? You can recognize a clickable battery by the large red button (see the photo below)

Of course we want to avoid this problem in the future. In my research into the Dyson vacuum battery life, I found out that a battery lasts an average of 5 years, but that there are a number of factors that influence the lifespan considerably. For example, it is best to recharge the Dyson at 20% battery life and it is recommended to use the vacuum cleaner in turbo mode as little as possible.

The lights on top of the vacuum are not on.
Hi Denise, what exactly do you mean? Is the LCD screen not lit?
My blue light is on while in charge mode but only stays on for about 10 minutes. The vacuum is not charging. There are no other colours of lights appearing. This is a 3 year old Dyson v7.
It is advisable to check the charging cable carefully (is it possibly damaged)? If there’s nothing wrong with that, it sounds like your battery needs to be replaced.
Hello, I’ve put my dyson on to charge and the blue light comes on for about 10 minutes then goes back off again
where can I buy a replacement battery?
Hi Rosemary,
There are several retailers that offer Dyson batteries. Think Amazon and Walmart. However, you can also buy batteries from Dyson itself. I strongly recommend that you buy a battery from the Dyson brand: they last longer and it is better for the life of your vacuum cleaner.

Hi! My Dustin v7 will only chat the or you jiggle it til the blue light comes on
Hi Gabriele, I don’t know exactly what you mean. A blue light is often an indication that your battery needs to be charged or that there is a blockage in the air ducts somewhere in the vacuum cleaner. The Dyson will also stutter.
