How To Fix Dyson Vacuum Not Charging
Dyson is a well-regarded brand known for its vacuum cleaners, but occasionally, minor faults can result in charging problems. Fortunately, there are several methods you can try to address these issues and resolve them effectively. By following these suggested approaches, you have a good chance of fixing the charging problems and restoring your Dyson vacuum cleaner to its optimal functionality.
1. Try Another Wall Outlet

It is important to thoroughly test your wall outlet when troubleshooting charging problems. Many people tend to overlook this step and focus on other potential issues instead. To start your troubleshooting process, it is advisable to begin with the original power source – the wall outlet. Sometimes, wall outlets can become faulty without our knowledge. To check if the wall outlet is functioning correctly, unplug the Dyson vacuum charger and plug in a smartphone charger instead. If your smartphone charges successfully, it indicates that the wall outlet is working correctly, and the problem likely lies elsewhere in the vacuum cleaner.
2. Inspect Your Charging Cord

The charging cord serves as the means for transferring DC power from the charger to the vacuum cleaner. However, if the charging cord becomes frayed or breaks, the current will not flow properly, resulting in the vacuum cleaner not charging.
Interestingly, a faulty charging cable is actually the most common reason why a device fails to charge.
To begin troubleshooting, carefully examine the entire length of the charging cord, checking for any signs of damage. If you notice fraying or any other form of damage, it is crucial to replace the charging cord promptly.
3. Clean The Charging Port

Having inspected the power source and the charging cable, it is now essential to examine the charging port. This component plays a vital role in transferring the current to the vacuum cleaner’s mainboard, which then stores it in the battery.
Over time, dust and debris can accumulate in the charging port, leading to potential issues. To address this, I recommend inspecting the charging port using a torch or the flashlight on your smartphone. If you observe any debris within the port, carefully remove it using a toothpick.
Once the debris has been cleared, it is advisable to clean the charging port using isopropyl alcohol. Afterward, insert the charger into the port to check if it begins functioning properly.
Try Another Charger
If your Dyson vacuum is not charging and there is no illuminated light, it indicates a possible issue with the charger. To confirm this, you will need a multimeter to test the current output from your Dyson vacuum charger.
To perform the test, connect the multimeter leads to the positive and negative terminals of the charger and observe the voltage difference displayed on the multimeter screen. Ideally, the reading should fall within the range of 21V to 26V (depending on the specific model of your vacuum).
By conducting this test, you can determine if the charger is indeed faulty and requires attention.

If the multimeter fails to display any reading, it indicates that the vacuum cleaner charger is non-functional, rendering it ineffective for charging purposes. In such a scenario, it is necessary to purchase a replacement charger to restore the charging functionality of your Dyson vacuum cleaner.
5. Replace The Battery

Dyson cordless vacuum cleaners are equipped with lithium-ion batteries that have a limited lifespan. When the battery becomes degraded, your Dyson vacuum will cease to function, necessitating the replacement of the battery pack.
On average, the lifespan of a Dyson cordless vacuum battery ranges from 1.5 to 2 years. However, the actual lifespan can vary depending on factors such as your charging pattern and usage habits.
If you notice a significant decline in the vacuum’s runtime or if a red light appears when connecting the charger, it indicates that the battery has undergone degradation and requires replacement.
6. Get Professional Help
If you have attempted all the previously mentioned methods without success and your vacuum battery still refuses to charge, it is highly likely that there is an electrical failure on the circuit board. In such cases, it is recommended to reach out to Dyson customer care or a reputable repair shop for professional assistance. These experts will be equipped to diagnose and address the specific electrical issue, providing the necessary expertise to resolve the problem effectively.
