If your device charges smoothly with an alternative charger (without blue light flashing) it means the original charger is the main culprit. Your issue will be resolved with a new and compatible Dyson V8 charger.

If the alternative charger does not solve the issue then you need to consider the next solution for the issue of your “Dyson V8 flashing blue light when charging”.

Inspect the Battery

Consider a battery replacement in case you have identified bad battery condition.

It is not technical at all and you can do it in a minute. All you need is to hold the handle on the dustbin assembly. Now press down the red button to detach the mop.

After detaching the mop, hold down the bin over the trash basket and press the red bin release button. You will see the bottom of the bin will open and you can empty the debris. Now wipe the bin with a soft cloth and reassemble everything. Put your Dyson on charging. There is an absolute chance that your device will be functional with no flashing blue light error.

Clean or Replace the Filter

There are filters in Dyson V8 that play a crucial role of trapping fine particles and keep the air clean. When you continuously use the device, these filters accumulate dirt or debris. This debris clogs the filter that restricts air flow and your machine’s efficiency is diminished. So, this overall activity makes a bad impact on your device. It detects inefficiencies and shows a flashing blue light as an indication that something is wrong with the filter.

Thus, you can clean or replace the filter carefully. Just make sure to unplug the device when doing this job and detach the dust container from the cleaner. Locate the motor filter screws and unscrew them. Detach the motor filter and clean them thoroughly. Do not using any chemical or pointed object to unclog the blocked filter. Similarly look for any damage. If you find physical damage to the filter, consider its replacement and you will be done with the solution for flashing blue light.
