This includes the frequency of the flashes of the LED light, which are significant indicators of the specific malfunctions that your vacuum cleaner may be experiencing.

Should you ever encounter a dyson flashing red light, it is indicative of a faulty battery, a common issue that arises due to the natural wear and tear of the device. 

It is essential to recognize that the sole resolution to this particular predicament is the replacement of the battery. 

Nevertheless, before proceeding with the battery replacement, there are several regulations and factors that necessitate consideration.

To ensure that the battery is indeed the root cause of the problem, it is imperative to undertake the following steps:

Once the charging has concluded, attempt to power on the vacuum cleaner to determine if the issue persists.

When a dyson flashing red light is observed, then the vacuum cleaner must be disconnected from the charging station and directly plugged into the appliance. 

On the other hand, if a flashing blue light is observed, it is advisable to attempt another charging session for the device, lasting roughly three and a half hours.

Few indications related to dyson flashing red light

In some of the more antiquated models of Dyson vacuum cleaners, such as those belonging to the Dyson V7 series, a red indicator light may also be indicative of a motor malfunction. 

While Dyson has not corroborated this assertion, many online forums suggest that the number of flashes of the red light may provide more information about the issue at hand. 

If the red light flickers more than 12 times, this may indicate that the problem lies with the battery, while fewer than 12 blinks may suggest a malfunction with the vacuum cleaner motor. 

It is also important to note that with extremely old Dyson vacuum cleaners, there may be a disparity between a flashing red light and a solid red light. 

If the red light is flashing, this may signify that the battery requires charging. Conversely, if the red light remains illuminated, this could indicate that the battery has suffered irreparable damage. 

It is crucial to recognize that this information is solely applicable to older Dyson vacuum cleaners and has not been verified by the manufacturer.


We highly recommend that you take prompt action to tackle the issue with your dyson flashing red light to prevent any additional damage. By doing so, you can avoid further harm to your device and extend its lifespan.
