Why is My Dyson Vacuum Blinking Red & How To Solve This!

The blinking red light will flash under 12 times if there’s a problem with the battery, while more than 12 flashes indicates a problem with the motor. In most situations, you can fix this issue by charging the battery.

The Dyson vacuum has a system to let you know when there’s an issue, but when you see the red light appear, what should you do? Here’s everything you need to know about Why your Dyson is blinking red light and how to fix it.

Fixing your Dyson is probably at the top of your to-do list to get your vacuum back up and running again, and thankfully, most issues involving the blinking red light can be fixed quickly.

The rest of this article will cover what the red blinking means and how you can solve any associated problems.

What does Dyson Flashing Red Light Means?

The red flashing light on the Dyson vacuum means that there is problem with the battery or that the vacuum filter needs to be cleaned or replaced.

It could also indicate a blockage somewhere in the system, so it is important to check and clear any obstructions before continuing with the use of the vacuum cleaner.

How To Fix A Dyson Flashing Red Light?

All models of Dyson come equipped with a red light that flashs when there’s something wrong with the vacuum.

It’s a useful tool to help you diagnose what the problem is quickly to avoid further damage to your equipment.

Check For Battery Problems in Your Dyson Vacuum

In most cases, the red blinking light indicates a problem with the Dyson vacuum cleaner battery, simply indicating that the battery isn’t working as intended.

The red light may be accompanied by the vacuum turning itself off, having a loss of power, or pulsing. In any event, fixing this issue is very simple. Start by charging your Dyson battery to see if it’s just a problem with the power supply.

In case, you use Dyson V12 like me and your battery is worn out, you should get this battery.

Charge Your Dyson Vacuum Battery

Leave the Dyson battery on charge for 3-4 hours, depending on the model you have. Make sure that the dock is set up correctly and plugged into the wall properly.

You should see the charging light come on when you have connected the two properly. Wait for the light to turn itself off before unplugging the vacuum from the charging station, and you’ll know that it’s been properly charged.

Once done, check whether the red light flashes has stopped. If so, then it’s likely that your vacuum was just alerting you to the fact that the battery was low.

Is Your Dyson Showing More than 12 Blinks?

More than 12 blinks indicates a problem with the battery. As mentioned above, in the vast majority of cases, the issue is simply that the battery is low.

If you charge your battery and the light disappears, then you don’t need to be worried about any issue with your battery; however, if the vacuum is unresponsive after being charged, doesn’t hold a charge for very long, or still persists with the blinking, then there might be something wrong with the battery itself.

Check For Low or Faulty Battery

It’s also worth noting that a Dyson vacuum’s battery will slowly lose charge over time as a simple property of lithium-ion batteries.

After a year, you might notice a decrease in battery life. If your vacuum is over 4 years old and your vacuum can’t hold a charge, then it’s definitely worth getting a replacement part.

If you’re getting the flashing red light with more than 12 blinks after almost every use of your vacuum, then it’s extremely likely that there’s a power supply issue and the battery needs replacing.

Check to see whether your Dyson vacuum is still under warranty, and if so, you may be able to get a replacement part from Dyson for free.

You don’t need any special tools or equipment to replace a Dyson battery, and it takes mere minutes to install and test a new one. First, make sure the vacuum is off, and then just remove the old one from the handle compartment and put in the new one.

You may need to charge your new battery before, so make sure to do so before testing it.

Replace Your Dyson Battery

You can remove the battery from the compartment on the handle without any tools, unless you have a newer model, in which case you’ll need a screwdriver to open it.

Check the battery casing for damage to see whether the battery needs replacing. If there’s visible damage to the battery, then you’ll need to replace it. Just make sure to get your replacement part directly from Dyson for the best compatibility and proper function.

Problem With Motor-Less than 12 Blinks

If the red light blinks less than 12 times, it indicates a problem with the motor. The motor is connected to the fans in the machine, facilitation the suction process.

When the vacuum is turned on and the fans are moving, a vacuum is created inside the machine, creating a low-pressure zone inside.

Air from the environment rushes into the vacuum as a result of the pressure difference. In essence, the motor converts electrical power into mechanical suction power, facilitating the process that makes vacuums a useful cleaning tool.

Whether it’s the brushes, shellac, or other instability, Dyson vacuums are designed to recognize problems with the motor and let you know via the blinking red light. A motor can go bad as a result of manufacturing defects, excessive vibration, or contamination of dirt and debris.

Heat-induced failure is common, which is why you always want to stay on top of your air filter cleaning and changes to avoid overworking the motor and having it burnout.

Symptoms of a bad motor include the following:

  • A bad smell (sometimes)
  • A clicking noise on startup
  • A red light blinking fewer than 12 times
  • Reduced suction power

In addition to these symptoms, if the problem with your motor is bad enough to cause failure, Dyson vacuums come equipped with safety systems that will shut off the machine entirely should the motor start to overheat.

Remember, the motor is influenced by the power supply and suffers detriment if there’s excess contamination, so it’s always worth checking for damage on the battery and cleaning or replacing your pre and post filters to see if the vacuum function improves.

If your vacuum is still under warranty (5-10 years), then you may be able to get a replacement part for free. Just be aware that you might be refused a replacement or be charged should the cause prove to be poor maintenance.

As with any other machine, proper care goes a long way, and cleaning your filters regularly with tap water and letting them dry out over 24 hours is a good practice. You should also replace them after 12 months of use.

Is Your Dyson Showing Continuous Red Light?

In older Dyson models, there’s a difference between a flashing and continuous red light. If the red light stays on, then the battery may be damaged beyond repair.

As before, open the handle compartment and check for damage on the battery casing. If anything seems amiss, it’s worth getting a replacement battery to keep your Dyson vacuum in tip-top shape.
