The dyson website had showed holding the conical top filter by holding the entire thing under running water - they NEVER showed or explained that it could be taken apart. My dyson's top filter was all caked up with dry, frequently-washed crud. Now the vacuum works, thanks to your demo. Many thanks.

[@PracticalMechanic]

Excellent observation, thanks for letting everyone know. Glad it's now working properly!

[@Spartan1293-w3u]

@@PracticalMechanic Ok How did you get a part without breaking it? If you did break it, can you gorilla tape it together and make it work?

[@DragonRollYumYum]

Great video!! This helped solve our Dyson pulsing problem - clogged filter that we never even realized existed. Thank you.

[@PracticalMechanic]

Excellent! So glad to hear it, thank you!

[@BobbiJoPraizner]

My Dyson was only pulsating on the high setting. After removing the cylindrical filter and testing it, the pulsating stopped. Your step-by-step instructions were incredibly helpful and reassured me that I was on the right path! Prior to watching your video, I had dismissed the filter as the issue because it looked pristine on the outside. I didn't realize that the filter was hollow and could be filled with fine dust, unlike other vacuum filters I was used to that captured dust on the exterior baffles. Your guidance saved me from making a trip to the local repair shop for a simple (but previously unknown to me) fix. Thank you!

[@PracticalMechanic]

Excellent troubleshooting! Glad I could be part of the process! All the best

[@Bennydm70]

V8 pulsing... it was the cylindrical filter in the top for me. Back to normal after a good clean. Thanks very much. 👍

[@PracticalMechanic]

Glad to hear it's back up and running! 👍

[@gregmanca1474]

[@AnnHiggins-k3r]

Thanks so much! I thought my filter was clean but after looking at your video, I gave it a good rinse and it was filthy! Put in a new filter and works like new!!

[@PracticalMechanic]

Awesome, so glad to hear it! Thanks for the feedback! 👍

[@risingwithhope]

thank you.... it was just something that got stuck in the tube. I got a new battery and everything but it was just that blockage.

[@PracticalMechanic]

Oh nice, glad you got it fixed!

[@barbaralorenzo7413]

THANK YOU!!! This solved our problem. We found the clog and now it works fine!

[@PracticalMechanic]

Excellent!!! 👍

[@sumi8625]

#4 Brutal! I trashed the plastic but finally got it off. The filters are trashed. Not even reusable so hopefully I can get those. Cleaned out all dust and tested the power - still surges so I guess new battery and flux capacitor 🤦🏽‍♀️

Start up the DeLorean, Doc!

[@jesswang03]

Clogged filter may have done the trick for me! I started out with a failed original battery. Dyson wanted something around $120 for an OEM, but like you said I was able to buy a (larger) battery for $32. It was kind of strange that the "pulsing" only started after I got a new battery. Thinking there was a problem with the new battery, I wound up returning it and getting a replacement. When there was the same behavior with the new battery, I knew that wasn't the problem. But, when I removed the filter, the pulsing stopped. So, I've cleaned that out and am assuming that was the problem.

[@PracticalMechanic]

Nice! Hope it works now.

[@djkrauss729]

@@PracticalMechanic What I'm thinking is that the new battery is working so much better than the old one that lost its ability to hold its charge, that the obstructed airway now really causes a problem (the air is being pulled hard enough that the restriction is causing a problem.) This means I've been working with 1/2 a vacuum for who knows how long!

[@PracticalMechanic]

That makes a lot of sense, good luck!

[@hypoglosal]

Thank you for saving me money…

[@darrenfisherman3838]

Get a brushless Makita they last plus the batter you can use on other same brand hardware. I had 3 and they all broken

[@workingbackground6522]

Even if taking the filter out makes it work, that might not be your issue I took the filter out and it works, but the issue was actually some hair and other stuff in the inlet pipe - guess the filter + blockage was restrictive enough to trigger the safe guard, but just the blockage alone wasn't.

[@PracticalMechanic]

Good tip, thanks for the feedback

[@louiseb5076]

Could it pulse due to a still wet filter?

[@PracticalMechanic]

Yes

[@paullawrence761]

I didn't realise it had so many filters on it

[@PracticalMechanic]

Yeah, kind of odd, honestly...

[@michaelbyers5509]

the pulsing only occurs when the long attachment with the roller is attached---why would that happen?

[@PracticalMechanic]

Perhaps there is a blockage in the long attachment somewhere?

[@KickAssets]

My v8 only does that when I attach motor head. I took Motorrad apart but no luck...hmm

[@PracticalMechanic]

This sounds like a bad motherboard. This is a somewhat common issue with these units. You can replace the motherboard, and this should fix the issue. Another approach I have heard is bypassing the protection circuit board. In other words, hardwire the battery directly to the motor. If you want to try that, proceed at your own risk: 1. Remove the battery. 2. Open the back of the unit so you can see the motherboard. 3. Disconnect the black and red wires coming from the battery. 4. Locate and disconnect the small red and white wires (may need to pull the motor out a bit). 5. Connect the small red wire to where the large red wire attaches. 6. Connect the small white wire to where the large black wire attaches. 7. Reassemble. Now when you pull the trigger, power goes directly to the motor and ignores the protection circuit. Because of this, release the trigger if the motor ever gets clogged or bogged down, otherwise you can potentially burn out the motor. Hope this helps, please like and subscribe! And let us know how it goes!

​@@PracticalMechanic Thanks for the amazing answer! Might be filter as it works when i take it out.

[@denisdurocher933]

I did all of this and it ended up being the battery

[@kevinlavin6633]

Where on EARTH are you finding Dyson replacement batteries for THIRTY dollars?

[@oscarrosales1962]

Amazon

[@juassie]

i bought a battery conversion kit so i can run a Milwaukee battery

[@nathaniel7186]

The official batteries are far more expensive and safer to use.

[@sumi8625]

😂

[@mylynne1953]

IMO, Dyson is simply an overpriced piece of junk. When they work as advertised, they are great. However, this is so seldom the case. Bad batteries, clogged filters , cracks in the plastic and several other issues are the norm. I've owned four of them and all have been troublesome. Never again will I purchase any Dyson product. Buyer be aware.

[@Desdanova]

It was the filter! Thanks!
