Dyson V7 Flashing Blue Light: Identify The Problem And Causes

If you’re a proud owner of the Dyson v7, you might have encountered the flashing blue light issue. This could lead to an unsettling experience, especially if you don’t know what the problem is. In this section, we’ll assist you in identifying the issue and its possible causes.

How To Identify The Flashing Blue Light

The Dyson v7 features LED lights that indicate battery life or any potential issues. To identify the flashing blue light, look at the rear of your machine, where you’ll notice the following:

  • A flashing blue light every second indicates that the filter needs cleaning.
  • A flashing blue light three times every second indicates that the battery is running low.
  • A flashing blue light every second while the trigger is squeezed: This indicates that there’s an issue with the motor or brush bar.

Check Battery Status And Charging

A flashing blue light three times every second is an alert for a low battery level. You need to charge your Dyson V7 as soon as possible. Here are some tips to ensure optimal charging:

  • To charge your Dyson v7 properly, it’s best to keep it between 20°C and 30°C.
  • Ensure the charging cable is connected securely.
  • Before charging, turn off the machine.

Possible Causes Of Battery Issues

If your Dyson v7’s battery isn’t holding a charge, it could be due to one of the following issues:

  • The battery may have run out of life or is faulty, in which case you might need a replacement.
  • Leaving the machine connected to the charger for an extended period. This could result in overcharging and damage to the battery.
  • Your machine might need a software update. Check if the serial number of the machine is accepted by the Dyson website and download the update.

Investigate The Filter And Bin

As mentioned, a flashing blue light every second indicates that the filter needs cleaning. Before you start cleaning, ensure the machine is turned off and unplugged. Here’s what you need to do:

  • Remove the filter by pulling the purple tab.
  • Rinse the filter under cold water until the water runs clear, and let it dry for 24 hours.
  • The filter should be placed back in the machine only when it’s completely dry.

Furthermore, a flashing blue light could signify a full bin or blockage. To solve the problem, you can do the following:

  • Remove the bin and empty it.
  • Check for any blockage between the bin and the wand.
  • Additionally, check if there’s any blockage in the wand or the wall mount.

Potential Causes Of Filter And Bin Issues

Apart from the reasons mentioned above, below are some additional causes that could lead to a flashing blue light:

  • Your filter might be clogged and need replacement. The lifespan of a Dyson V7 filter is about six months.
  • Ensure that your machine’s bin is inserted securely. A loose bin will lead to a vibrating sound, and the machine won’t work.

Identifying and resolving the flashing blue light issue in Dyson v7 is relatively simple if you know what to look for. Ensure you conduct regular maintenance to prevent this from happening and enjoy using your Dyson v7 to its fullest potential.
