Dyson V7 Troubleshooting Pulsing

If your Dyson vacuum begins to pulsate on and off or only operates for short periods of time, this is due to a blockage in your unit or its charger. A Dyson cordless vacuum will begin to notify you of a potential problem by shutting off or pulsating, indicating a problem.

Dyson vacuums, according to its online help page, are meant to notify consumers of possible problems, thus pulsing is totally normal. Again, it’s a good idea to check your vacuum’s dirt bin and make sure you’re charging it on a regular basis.

How Do You Restore A Dyson Cordless Pulsing Vacuum?

Fixing a pulsing cordless Dyson vacuum isn’t very hard.

To start:                                                

  • Check your vacuum, pressing its bin release button.
  • Empty your Dyson’s dirt bin.
  • Separate your vacuum’s bin from its cyclone.
  • Remove the entire bin from your machine.
  • Clean the area with a cloth or dry brush.
  • While your bin is removed, check your Dyson’s inlet flap for blockages.
  • Check all attachments for blockages and remove any debris as necessary.
  • Clean out your vacuum’s motorized head, undoing its end cap fastener.
  • Remove your Dyson’s brush bar and cut away any hair/fibers from its bristles.
  • Reassemble your machine, test it, and you’re good to go!

If you have cleaned your Dyson filter and allowed it to dry overnight before inserting it into your vacuum, yet the pulsing persists. The Dyson filter must be replaced.

Dyson V7 Not Charging

While a faulty battery is most likely to blame, there might be other causes. The following are the most essential reasons:

  • The Dyson battery is not correctly attached to the vacuum cleaner
  • Your Dyson vacuum cleaner’s battery is worn out 
  • The Dyson battery is not correctly attached to the vacuum cleaner 
  • Your Dyson vacuum cleaner’s battery is worn out 

How to Spot a Dyson That’s Not Charging?

There are a number of indicators that a Dyson is no longer charging. When you plug in the Dyson vacuum cleaner, for example, the light no longer illuminates (after all, there is no battery power).

  • The Dyson won’t turn on, even after charging for the minimum number of hours.
  • A red light will flash, indicating a worn-out battery.
  • The blue light does not come on when you charge the Dyson battery.
  • If you have a newer Dyson with an LCD screen (for example, the Dyson V15 Detect), you will receive a message on the display when charging.

Solution: You May Recharge the Battery This Way.

You cannot use a Dyson vacuum cleaner if it is not charging. As a result, it is critical to resolving this issue as quickly as feasible.

First, make sure the vacuum cleaner isn’t just out of power. That is why it is best to charge the Dyson for the shortest amount of time first. And, while this may seem hopeless, it may save you from purchasing an extra battery for nothing.


The minimum charging time for each Dyson vacuum cleaner series is listed below.

Dyson serie Minimum charging time
Dyson V6 190 minutes
Dyson V7 221 minutes
Dyson V8 301 minutes
Dyson V10 210 minutes
Dyson V12 (Slim) 280 minutes
Dyson V15 Detect 275 minutes
Dyson Omni Glide 208 minutes
Dyson Micro 1.5kg 237 minutes

Have you charged the Dyson for at least the specified amount of time? Then you may use the following checklist to help you pinpoint the issue.

  1. Is there a red light that is blinking? Then there’s the issue with the Dyson battery.
  2. Is there no flashing red light? When you insert the charging wire into the Dyson, see whether it flashes blue light.
  3. Is there absolutely no light? The charging cord and/or charger may also be defective. Examine the cable for any signs of damage or flaws.
  4. There are no noticeable flaws on the charger? Then, ensure that the Dyson battery is securely attached to the vacuum cleaner. Remove and replace the vacuum cleaner’s battery.

From experience, I can say that in many cases the problem will lie with a defective battery. Replacing a Dyson battery for a new one is often the only solution. Although this entails additional costs, the replacement itself does not require any technical knowledge.

Many users want to know if they can reset a Dyson battery. It is not feasible to reset a Dyson battery, however, it is always a good idea to replace the battery in the vacuum cleaner.

New Dyson battery? Check these tips first!

Before you just buy a new Dyson battery, it is smart to read the tips below carefully. This way you may still have a warranty on your battery.

  • Check to see whether your Dyson battery is still under warranty.
  • Always use a Dyson battery; general batteries might cause damage to your Dyson.
  • Check that the battery is compatible with your Dyson vacuum cleaner (check your serial number in the booklet ‘Which Dyson do I have?’).
  • Choose the correct sort of battery: do you have a click-in battery or a screw-in battery? A clickable battery may be identified by its huge red button (see the photo below)
