Dyson Vacuum Has No Power
It can be pretty frustrating to pick up your Dyson vacuum and discover that it has no power. But don’t fret, you’ve come to the right place! In this article, you will discover the top reasons why both corded and cordless Dyson vacuums have no power.
If a corded Dyson vacuum has no power, check that it’s receiving power from the wall socket. Then, ensure the power cord and plug are free from damage. On cordless models, the battery must be fully charged and free of damage before use. Damaged batteries or chargers could produce no power. Lastly, both corded and cordless models will cut their own power if they overheat from a blockage.
Let’s take a closer look at each of those possible reasons your Dyson vacuum has no power.

When troubleshooting or repairing your Dyson vacuum, always be sure to disconnect it from its power source. That means removing the plug from the wall socket or removing the battery pack for cordless models. Doing this will avoid the danger of electrocution and reduce your overall injury risk.
Dyson has a wide range of vacuum cleaners, both in corded and cordless form. Here are the most likely reasons that a corded Dyson vacuum has no power.
Incoming Power Supply
Before troubleshooting the Dyson vacuum, check that there is indeed an incoming supply of power. That means checking that the breaker hasn’t tripped and that the wall socket you’re using is functioning as it should.

Why it fails:
If your Dyson vacuum has no power, there may be no incoming power supply. That means the circuit breaker might have tripped, the wall socket is faulty, or that your household isn’t receiving electricity, to begin with.
Before troubleshooting the vacuum, this should be the first issue that you check and resolve.
How to fix:
Suppose the breaker tripped at the household’s main electrical box.
- Simply switch the breaker back on. If the wall socket is problematic, it would be best to use another working one in the meantime.
Power Cord and Plug
Corded Dyson vacuums will have a long insulated cord that leads from the machine to the wall socket. This power cord will have a plug on one end that goes into the wall socket. The other end will connect directly to the vacuum motor on the inside of the unit.
Why it fails:
After being in use for a long time, the Dyson vacuum’s power cord can suffer a lot of damage. You might find that it has tears and rips from years of being twisted, stepped on, or from experiencing general wear and tear.
When the power cord is damaged, the Dyson vacuum will not receive the power it needs to function.
How to fix:
You can purchase a replacement power cord that also comes with a new plug. However, if you’re not confident about replacing it yourself, it’s always best to contact a qualified technician.
If you decide to do it yourself, however, here’s what the process will look like.
- First, you will need to access the vacuum’s switch cover and disconnect the existing power cord from the power switch.
- Then, you can connect the new power cord to the same terminals.
Blockage and Overheating
Suppose you’ve been using your Dyson vacuum for a while and turned it off for a while. If, after that, you discover that the vacuum has no power, then it could be that the vacuum has overheated.
Typically, this happens because there’s a blockage somewhere in the vacuum, causing it to overheat. To protect the vacuum from damage, a safety fuse would have shut the vacuum off entirely, which is why there’s no power when you try to use it again.

How to fix:
To fix the problem, you will need to clear out any blockage in the vacuum.
- Then, take apart the powerhead, wand, and hose so you can inspect and clean each part individually.
- Once that’s done, you can put the vacuum back together again and test it.
Remember:
The safety fuse which tripped when the vacuum overheated will not reset until the machine has cooled down entirely. So, you might have to wait an hour or so before you can try to use the vacuum again.
For cordless Dyson vacuums, the reasons why there’s no power are somewhat different. Here are the issues and parts that you will need to troubleshoot:
Battery Has A Charge
Your cordless Dyson vacuum gets all of its power from its battery. These batteries are pretty powerful, but they also require plenty of time to charge up to full capacity.
Why it fails:
If you find that your Dyson vacuum has no power, check that the battery has been fully charged. Unfortunately, Dyson batteries have a limited runtime and will drain after about 30 minutes or less.

So, if your Dyson vacuum has no power after you’ve been using it for a while without recharging, it’s likely that the battery has simply run out of charge.
How to fix:
To fix this, simply provide your Dyson battery with ample charging time.
- Typically, these batteries require 3 hours to charge completely.
- After that time, test the vacuum again.
Be sure to refer to your vacuum’s user manual to learn how long the battery for your model is expected to last. In addition, you’ll find different modes (e.g. MAX mode) that can consume more power and drain the battery faster.
Battery Damage
A lack of power can also come from a damaged battery pack. For instance, a cracked or damaged battery pack might cause it not to hold a charge like it used to. That will cause your Dyson vacuum not to have any power.
Even without any physical signs of damage, the battery pack will flash a red warning light to tell you that it is faulty. On some models, that red light will flash 12 times or more, though that will depend on your model.
Be sure to refer to your user manual to understand which flashing lights indicate a battery failure.
Why it fails:
Battery packs can fail for several reasons.
- Firstly, impact from being dropped on the ground repeatedly can cause problems for the battery.
- Besides that, being exposed to excessive heat or moisture can also cause the battery to stop working as it should.
How to fix:
Unfortunately, battery packs cannot be repaired. So, the only solution to this problem is to purchase a new battery pack entirely. Please remember to dispose of the damaged battery properly, according to local rules and regulations.
