How To Fix Dyson Vacuum Not Charging

Dyson is a reputable brand for vacuum cleaners, but sometimes it faces charging problems due to minor faults. Try these methods to fix the problems-

1. Try Another Wall Outlet

Dyson Charger Test

Have you tested your wall outlet? People often test other things except for the power source. I would advise you to start troubleshooting with the original power source. Because sometimes our wall outlets get faulty and we keep checking other things.

Remove the Dyson vacuum charger from the wall outlet and insert a smartphone charger to see whether it’s charging. If your smartphone charges, it means your wall outlet is functioning, and the problem lies elsewhere.

2. Inspect Your Charging Cord

Dyson Charging Cord

The charging cord is a medium of DC power transfer from the charger to the vacuum cleaner. The current won’t flow to your vacuum if the charging cord breaks or gets frayed.

You won’t believe that a faulty charging cable is the most common reason why a device won’t charge.

First of all, inspect the charging cord from head to tail and ensure there is no sign of damage. If your charging cord is frayed or damaged, please replace it immediately.

3. Clean The Charging Port

Dyson Charging Port

We have inspected the power source and power carrier. Now, it’s time to inspect the charging port because this component sends the current to your vacuum mainboard, which is further stored in the battery.

Because of regular use, some dust and debris clog the charging port. So, I would advise you to inspect the charging port with the help of a torch or smartphone flashlight. If you notice any debris in the port, carefully remove it with a toothpick.

After removing the debris, clean the charging port with isopropyl alcohol and insert the charger to see whether it works.

4. Try Another Charger

If your Dyson vacuum is not charging and no light glows, it means your charger is faulty. To ensure this, you need a multimeter to test the current output from your Dyson vacuum charger.

Attach the multimeter leads to the positive and negative terminals of the charger and reads the voltage difference across both terminals. There should be a 21V to 26V (depending upon your vacuum model) reading on the multimeter screen.

If you get no reading on your multimeter, it means the vacuum cleaner charger is dead, and you need to buy a replacement.
