Why Does My Dyson Vacuum Keep Pulsing ON and OFF?

Dyson has introduced some of the best cordless vacuums like the Dyson V11, V8, and V15. It is the first brand that utilizes cyclone technology for cleaning dust from the vacuum cleaner. It does not lose suction over time. However, why Does My Dyson Vacuum Keep Pulsing ON and OFF?

Dyson vacuums have powerful suction for home cleaning, including carpets and all floor types. It offers a range of the best vacuum cleaners in the market. Most of the Dyson vacuums are intelligently engineered with a robust battery and motor.

But they are designed to pulsate. It is an audible feature that prevents damage to the motor but indicates a problem. It results in airflow restriction or a blockage within the machine. The vacuum keeps starting and stopping, which does not give a continuous suction stream.

Does your vacuum also face pulsating problems while stopping and starting? If yes, then do not worry! We will tell you the practical ways of troubleshooting the problem for all Dyson corded and cordless models. Here we go!

Ways to Troubleshoot the Pulsing Problem

Power problems

Ensure that your corded vacuum is plugged in properly or fully charged if it is a cordless vacuum. A cordless Dyson dustbuster like the V11 is lightweight and powerful, but they require charging regularly. A charge is especially needed if you are using the device in MAX or extra powerful mode.

You could have placed the battery improperly on the charger, resulting in the improper working of the device. The Dyson V11 drops quickly into a wall-mounted dock to fully charge it. However, once the device is charged, ensure to unplug the device before turning it on.

Cordless vacuums like the Dyson V8 do not tend to work on being connected to a power outlet. The battery life of an electronic gadget tends to degrade over time. If your Dyson vacuum is no longer charging or lasts only for a few seconds on the MAX mode, then it is time to replace it.

Also, make sure that the cord of a corded Dyson dustbuster is not damaged and correctly plugged in. A damaged cord can shut off the device repeatedly.

Turn off max mode

Mostly, a flashing light indicates that the vacuum’s battery requires charging. However, flashing lights may also point to a blockage in some specific Dyson models. Max mode is meant for powerful or intensive spot cleaning. It boosts the cleaning but results in battery degradation on using Max mode constantly.

Look out for your device’s MAX mode when your Dyson cordless dustbuster keeps pulsating on and off. If the MAX button flashes and lights up, hold the power button and depress the MAX button to turn off the function.

Check for blockages and tangled hair

If your Dyson dustbuster is stopping and starting or making a high-pitched noise, check the bin inlet. You might have to empty the bin as it may be full. Dyson vacuum cleaners need continuous airflow for smooth working. However, a full bin can stop the airflow. Check for dirt stuck in the bin’s top part. It may require a knock or two, or you can also clear the bits with a blunt object.

The Dyson V11 has a point-and-shoot mechanism that ejects debris and dust in the bin hygienically. So, you do not need to touch the dirt. The V8 Animal quickly converts from a stick to a handheld device with one click. Look for any problem while working on the Dyson vacuum without a long sweeper attachment. If yes, then you might have a clog in the attachment.

Use a flashlight to check for clogs on the sweeper end or tangled up fibers in the roller. Do not ignore checking for blockages elsewhere, like the stick, wand, and hose for the cylinder. You can use a flashlight to check other parts, especially the valve lying at the wand’s top, where it is attached to the canister.

Other items that can block include tool attachments like motorheads that can create a problem with tangled hair. Sometimes, it might become necessary to open up the cleaner head. You can do it by using only a coin in the Dyson V8 Animal.

Cleaning the filters

Let me tell you that filters might look clean at first glance, even if you have not washed them recently. However, it is likely that dirt and dust are hiding inside the filter. So, how will the dust appear?

Try removing the filter and observe whether the vacuum runs smoothly or not without pulsating. It will help you decide whether the filter is having issues or not. The vacuum will not suck properly without a filter, but you will know whether clogged or faulty filter results in your Dyson pulsating on and off.

Dust will be apparent once you begin washing the filters. Dyson recommends washing filters in cold water without soap or detergent until it runs clear. You can twist and squeeze the long pre-filters to remove the dirt inside.

You can rinse the post-filters while not damaging the pleats inside. Many Dyson models like the V8 Animal have HEPA as the post-filters that prevent allergens in and around the home. It is easy to clean up high and in between corners. It takes approximately 24 hours for the filters to dry. There is no need to put vacuums’ filters like V8 and V11 in the tumble dryer or oven.

Filters will dry properly in any place slightly higher than room temperature. Ensure the filters dry completely and are free of dampness when you put them back into the device. If not, they might leave an unpleasant smell. If you think your filter looks worn out or smells strongly even after washing, it is time to buy a new one. Make sure to fit the new one properly while replacing the filters.

Checking for flap in the vacuum head

Some Dyson cordless vacuum cleaners might contain a flap inside the vacuum head that can be stuck. The bin inlet flap can get jammed and pulsate the gadget on and off. Try removing the bin by pulling the cyclone release catch upwards till the bin base opens.

Press the red catch that lies under the bin once you open the bin base to release it from the machine. Clear debris from bin inlet flap’s behind. After disconnecting the attachment, locate the flap inside. Push the flap gently to make it lose.

Clean the vacuum

There will be a need to deep clean the vacuum thoroughly if your Dyson is stopping, pulsating, or making a noise. You should clean the gadget thoroughly by shaking or tapping the dust bucket or flapper to release the clogged dust. No matter if the filter looks clean from the outside, you should try to rinse it monthly.

It is easy to remove the dust bucket for vacuum’s thorough cleaning. You have to pull the red release tab once to open the flap and a second time for detaching the dust bucket. The powerhead or neck of the cleaner house clog ports allows removing blockages easily. The powerhead is located at the vacuum’s base that offers brush roll height adjustment for cleaning varied floor types.

Conclusion

Dyson offers premium quality vacuum cleaners with the latest intelligent technology. However, the vacuum faces constant shutting on and off due to some issues in the attachments. But do not worry! The above checkpoints will help you understand the reasons behind vacuum’s stopping and starting.

These will help you fix the pulsating issue effectively. However, if you implement the above tips and still think your device has problems, you can contact the manufacturer.
