- Crazy Dyson v8 Fault and Repair
This Dyson cleaner was playing up and not in the usual pipe or filter clogged way. Luckily enough I investigated it as it really is a dodgy problem with it - must have been a Friday afternoon build in the factory?

Thanks you lovely people, and keep on tinkering!
I did training with Dyson to disassemble these. They have 3D printed tools to release various tabs and clips.
As we'd all taken one apart they couldn't sell them so we got to take them home :)
This is fascinating, makes a lot of sense
Took me half an hour searching, but this is the first video that TRUELY shows how to open the main body and not a 'complete teardown' where they just remove the rollers and crap. Thank you.
You are most welcome, I am so glad it helped!
Yes I agree
You, my friend, are an absolute life saver! I bought my Dyson V8 at Target🎯 a year ago and it acted weird right out of the gate. I paid over $400 for it but chose not to return the thing because it worked great...when it worked. I was getting more annoyed with it as time went on. Then, I came across your video, after searching MANY videos. I tore it apart yesterday and found that the power wire on the right had a cross-threaded screw. I ran a die over the screw and a tap into the attached nut to fix it. The other problem was the star slot in the screw was only half formed so I had to use needle nose vise grips to put it back in. It works great now.
You would think that whoever put it together would have noticed that it wasn't in correctly. They should be ashamed of themselves for sending this product out for sale.
Thanks for the tutorial👍🏻!
That's fantastic to hear it worked out
You just saved me a couple hundred bucks. I was vacuuming and didn’t realize my daughter spilled her water under the table until I seen it in the collection. The vacuum immediately stopped working and all of my husband’s research said it was trash. I refused to accept that, followed your instructions to reach the motor and wet sponge cover(V7 Pet version), dried it out slowly with a hair dryer on low, and now it’s back! Thanks so much!!
Wonderful to hear! Glad you got it working again 👍👍👍👍
You just saved me hundreds of dollars! I would not have take the body fully apart without seeing you do it first. It ended up being a loose screw for a power wire. After watching everyone else's videos being about cleaning the unit, my wife's is not only fully cleaned now but working like new! Thank you
Fantastic, good to hear it!
My V8 was pulsating and not holding a charge. Thought it the battery. On replacing it, flame and smoke shot out of the back of the motor. That was enough for me. Costco has a return policy and this is going back. I’m thinking a similar problem as you describe but I think the circuit board is toast. Glad the house is still standing!
There are plenty of alternatives out there to the Dyson fortunately, and most without the flame thrower function!
Look at the absolutely miniscule fan on this vacuum! Just took mine apart - it measures 20mm in diameter - 3/4"! Its about as big around as my thumb. Not sure weather to commend Dyson's genius in getting any kind of vac to work at all with that tiny a fan, or wonder if they really know what they're doing. Mine works ok on high (when it's very loud and only runs about 3-4 minutes) but honestly on normal it's just not a lot of suction.
THANK YOU!!! After going through many videos that say full disassembly your's is the first one to actually do it.
Thanks William, great to hear it! Fantastic!
Hi thanks for this - I had an issue on my V7 where when I set the machine to max power it would die after 5 seconds of use. After taking it apart I saw that the black wire had been damaged (presumably during the manufacturing process). Not something that I can fix myself, but I phoned Dyson support who were really good and they organised a replacement.
Damn right their support should be good for the price they charge for these 😂
I'm all about the G-Tech now, far better machines if you are ever looking for a replacement
Mine had the same symptoms. I've broken the O ring taking this apart (will have to find another one). However I did not find the same screw damage/shorting issue that you have here.
This was very satisfying to watch. I always wondered how to open up the rear end as I have one. Mine also developed a crack on the handle and replaced by Dyson. Despite this hiccup, I still love the Dyson. I also agree with other comments that the batteries need to be of easy changing like power tools.
The operation mode switch button is not set as you have shown!
awesome video thank you , did you find out how to
put back spring button on top
i am finding it the most difficult part , please advise .
Did you fix the magnetic suction switch? I also took mine out and cant get it back the way it was with the spring in the right place...very frustrating lol.
I believe I got it working, but I know what you mean. There are 200 ways to install it, 199 of them are floppy!
Did you ever figure this out? I’ve tried what seems like a million different configurations to reassemble it to no avail.
@@ryancurry8918 I never could figure it out, I have to tape it down to either regular mode or max suction...
Hello, i change plastica case about dyson v8, now the button of Speed (normal, fast) work only at normal Speed. I try with the small magnet inside button, but don't change speed
My v8 does not work when I plug in my electric roller head
I have taken my vacuum apart and have the motor out. I am getting resistance between my negative lead and my negative wire that goes down the vacuum to the roller head.
Have you heard of this happening?
Isn't the resistance the coil of the motor in the head? Are you seeing voltage on the contacts to the head when you operate the vacuum
I have cleaned all fillters of my Dyson V8 Absolute and motor still pulsates. Doesnt matter if I am blocking the outlet where wand fits or not. Motor continually pulsates. Does this mean a new motor?
Did you figure out how to reassemble the power setting switch so that the spring engages correctly? I'm struggling with it atm. Thanks.
Same here... many months later.
@@lesrogers7310 if you guys are still having issues, lmk and I can post a video on how to do it :)
Any luck figuring out how to reassemble? I’ve not been able to figure this out either.
@@jakesteele848 please do!
very nice, the only one online that I can find to actually open the motor module. This helped me to fix my motor problem.
Glad it helped!
It s because if you open the motor your warranty is amended ... So it is better to contact Dyson and let them help you.
Opening does not void the warranty. There are absolutely zero tamper indicators in place to prove it was opened.
My failure involved the accessories getting power (voltage) but not actually spinning. No current was passed from the PCB to them. The wires were fine, these wires are the red and white ones in the video. So it is some kind of programmed chip death I guess..
As a hacked up fix, I just pulled the white and red wires out (they are held in by clips on the back of the pcb which you can unhook with a screwdriver) and I put those red and white wires directly onto the big bulky motor leads by shuffing them under the screws (between the wire terminal and the screw, NOT BETWEEN THE TERMINAL AND THE SOLDERED NUT- this will cause FIRE because the big leads need to be able to pass 40 amps to the board by making full contact).
The accessories now spin again- but you may want to add a fuse onto one of the leads though because if an accessory shorts out or is blocked in some way it's gonna get the full power of the battery and also burn something up. Good stuff.
Gotta love making these expensive toys more dangerous.
I just found this video after searching dozens of others. My symptoms also mirror yours (no power to accessories). I'm eager to try getting it part and seeing if I have a similar problem to yours. Did you also have the intermittent power (pull trigger, blue light on battery but only power to the blower occasionally?)
I just went back to 9.30 and checked where the wires went. The ultimate 20/20 hindsight. Good video.
I had thr EXACT same fault on mine. A cross-threaded screw that had come loose and I fixed it exactly the same way. Thank you for this video!
Hello, great videos. I am looking for some explanation of my Dyson V8 fluffy slim + (SV10K). this variant does not come with the carpet 50w direct drive/motorhead, only the hard floor fluffy ones (15W) , it also comes with the small motorised head 20W. Then i realize I need to also deep clean my carpets and want to get the 50w direct drive head that usually comes with absolute variant. When i manage to try the 50w head on my V8, it spins but as soon as put on carpet and senses load on the head motor, it stops spinning. I did some amp reading and seems like my v8 only allow certain amp draw from the attachment but not the 50w head because its higher, way higher than the motorized head that it came with in the box. Do u know if there is any way we can change the amp draw limit to support the 50w head attachment.
Just bought the Dyson V8 Absolute. It's brand-new, and it's not working even the battery is totally fine. I also removed the back purple filter, and place it again, and it turned out a bit, but they it went off. I believe mine also has the same defect.
They are dreadful, I've seen happen several times. Faulty out of the box
@@backofficeshow I already placed a return request. I bet they work great, but they have many issues and they are high maintenance. I was looking for something that makes my cleaning life easier. 😭
@@AdrianRConant I quite like the robot vacuums now, the Xiaomi or Roborock models with the LIDAR are amazing. I sometimes feel sorry for them they work so hard 😂
@@backofficeshow actually that was my first option. LoL but honestly, Dyson's marketing convinced me. 😅 I was checking the Romba. Any suggestions?
@@AdrianRConant If I was in the market at the moment I think this unit would be a strong contender amzn.to/3iJnN9B
Thank you, my unit had the exact same problem. I put a new screw in too and it works fine now. Thank you for the video.
On my sister's one of these the power is not getting down to the motorised rollers at the end of the tube. I checked continuity of the pins to holes on the tube, attached a DC power supply to the pins on the roller mechanism and they whizzed around so the motor works. Just no power getting down from the main body, any ideas?
Keep checking continuity upto the body, it can either be a break in the circuit to the PCB or a component in the PCB.
With a bit of luck hopefully it will be a mechanical issue you can fix.
Same with mine.
No power coming out for the accessories.
Just found the same issue with mine. Works a treat. Thanks
12:30 super glue / CA will work to repair that O ring as well. Its actually a method to create O rings in the pro shops as well.
I measured the the voltage and it reads 20v, I also check from the brush spinner with a 9v battery and it spins but not sure why when it's not Turing with its own power. I checked all the connections and no issue.
It could be one of the sensors in the machine from not working correctly.
@@backofficeshow I found it in the trash 🗑, I figured I can fix it. Once I open the machine the circuit pcba has water damaged and white corrosion.
Does the waste canister have a little flap around the nozzle? I think there's supposed to have one and mine doesn't, causing the dirt to fall out.
My dyson brush isn’t spinning how can I fixed that I have tried everything and I mean everything I think it must be the electrical it’s not going through to make the brush spinning
My Dyson v8 start running all the time, even without pulling the switch button. It only stops when battery was disconnected.
Any ideas?
The switch that is connected to the trigger is built into the battery, you can check this yourself. Perhaps a new battery will solve it?
@@backofficeshow I guess that's the only option. From what I understand battery should power the device only when build-in switch is on, not all the time. Thanks for the tip!
Thanks for your Extra info about this topics
Had the same exact problem. Thanks for the vid
I'm glad it helped!
Can you make this dyson work corded ?
Thank you for this video!! Helped me get the trigger out.
Fantastic!
I'm pretty sure i have the same problem. But none of the brush bars works anymore as well, meanwhile i still can measure current over the 2 connecter points. Do you think this fault could've damaged all the little motors in the vacuumheads? And if you open it and can show this is the case, will Dyson fix/replace some parts?
I suspect getting a new brush bar will be your only option via Dyson. If it's broken you have nothing to lose having a look if you can get it dismantled
Use a 9V battery on the motorhead to test for any movement. Best to take out the dc motor to test in case it’s just hair jamming it up. If there’s no jam and it moves, you have no power from the main unit. Follow for continuity from the Motörhead’s dc motor up to the connection to the main unit. If all is well, your issue is a chip burnt out that feeds the power tools. Can bypass by connecting the red and white wire to mains. Add a an inline fuse if you do this in case of motorhead failure and high current is drawn.
@@randycollens2681 i need to do this, how many amp fuse should be used.
Anodizing on a power connection screw is like a cardinal Sin in the electronics world. I'm trying to figure out why my Dyson V8 no longer powers the attachments. I love your video on how to break it down tho
Hopefully it will be something simple - good luck on your investigation!
Did you ever figure it out? My V10 stopped running the attachments as well. Hoping it’s an easy fix and not the board itself. I am getting the power into the board but not out of the board…
@@ShopWithEmily I had to replace the main board
Single malt prune juice?
The best kind
hi. Where to buy electronics for battery repair for dyson v8?
Mine was "pulsing", so I cleaned the filters, to no avail. Then I finally thought to check the mouth of the Bare Floor Tube - an entire Bounce Dryer Cloth was jammed up in there, gahhhh. Easy fix, and it works like a charm again.
Thanks for this! Great video and funny commentary
Glad you enjoyed it!
Now i challenge you to dismantle the bin dust , good luck
I feel confident
merry christmas and a great weekend
Thank you and seasons greeting to you as well!!
thank you sir
Hello, maybe you can assist.
where can I find a replacement for the red lever that is used to open the bin?
Here in Israel, while under warrently, mine broke in the middle, and they don't have this piece and ask me to replace the entire bin for a very very high cost...
Can you access eBay from Europe? I think that ought to be your best bet
fixed my issue - thanks!
Wonderful!
Prune juice "A warriors' drink." haha! Merry Christmas! :-)
Merry Christmas to you too, human!
Excellent Video, thank you very much!
I think I have a different factory error.
I have a V7 and V8. The V7 I just got wouldn’t spin up at all and would just flash an LED on the battery when you pull the trigger. The V7 is almost identical to the V8 except there is no removable rear filter, which means you need to pry it off and there is no cage or additional duct to pry inside. I’m not sure about a screw deep in the handle but if there was one I didn’t need to remove it to get out the motor.
Before I got that far I reached in and tried to turn the impeller blade but it wouldn’t turn. It turned freely on my V8 so I figured the V7 was seized up and proceeded with the motor removal.
Anyway, I suspect this was another factory error because everything looked brand new on the main housing, inside and out, without even a spec of dust. Nothing like my V8… stark contrast. It was as if it had never run at all.
The stuck motor felt a bit crusty when I forced it to turn by hand but after forcing it was turning freely again. Took less than a few turns. After reassembling it seems to work fine.
This wouldn’t be the first time I’ve seen such a factory fault: Decades ago I had a new laptop CD-ROM that behaved exactly the same way where I had to manually turn it past a crusty-feeling spot before it could turn on its own and read discs.
Those batteries must be packing some serious current to melt a screw and washer like that!!
Hope this fixes mine. My dyson failed after ~1000m2 of use. It's a freaking joke of a product
same crack in my v8 , and nobody admit to drop it . maybe its a design flaw in those units....
I suspect so
Merry Christmas Andrew! I've been fascinated with those Dyson vacuums since I first saw them on TV. Do you recommend them?
From a technology standpoint they are interesting, however, from a build quality I'm not so sure. I think personally I will look at other solutions when my one expires. My parents have the latest model and that failed within a few days and was replaced. This does not give me confidence in the product.
as I user, I see two flaws in the design of Dyson vacuums: 1) replacing battery needs tools. this is the most fetal one, as many home appliances and tools are getting wireless models, battery replacement and compatibility among themselves is a very important product design strategy. It's unfortunate that Dyson designer did not see this coming as this products was started a bit too early for this. They could have learned this quickly and make new models with one-click replaceable batteries, and offer at least two batteries per device; 2) the location of the motor is in the path of the air flow, which is some time fetal. As we often wash the filters, the mix of water and dust will form mud in the air path and on the motor wheels, and jam and lock the motor, as it did to my motor, if one washes the filter, then blows the motor a bit, and then leaves it on stand for a few days. However, among all the vacuums on the market, Dyson still has the most powerful motor which many loves. I hope Dyson engineers can watch this video and read my message here, and go back to their design board to make a better vacuum.
Dyson really wants you to break it and but a new one.
@@backofficeshow The v8 has 3 phillips screws for the battery, but the new V11s have removable one click batteries and include two batteries and two chargers
@@backofficeshow hi, my dyson v10 no longer works, when I press the button there is a slight motor noise for 1/2 seconds and then that's it, what could be the problem? thank you
My glass of prune juice is a 10% beer
Excellent
Mine blew up used only five times
Thanks alot.

Seriously, battery being screwed in to secure it and the motor using its own suction for cooling are your two complaints... wow. Just wow
You can use no contact cleaner and spray the PCB from time to time
thanks for sharing
When mine did that same thing, it was the battery that was the issue and not the machine. 98% of the time, its the battery that is at fault.
I think mine is on its way out, it only lasts 2 minutes on a charge and is less than a year old.
I'd clean the damaged contact surface as well.
I had the same problem with the red cable! Lame engineering/manufacturing!
They are really crap. I'm using GTech products now instead
they seriously don't want anyone taking their stuff apart..
Yeah, basically the Apple of home appliances. My parents are also on their second after the first died within days. Basically shite. I cant recall in my whole life another cleaner I bought failing from normal circumstances.
That’s a shame, my DC04 is a lovely machine to take apart and repair. Probably why it is over 20 years old and still going strong!
If you are wondering how your Dyson got cracked, take a look at how you slap it around in this video. The plastic Dyson used is absolute garbage. I cracked a couple parts by giving the old bump push together like you did. Be careful, it doesn't take much shock to crack that cheap brittle plastic. Even pushing in the battery with a little bump (like with power tool batteries) will shatter the cheap plastic battery receptacle inside the handle.
I agree, Dyson products are the biggest pile of turds. Their marketing department are geniuses
Yeah it's over-engineered but it's better than the shite Gtech Air Ram
Put the bin 1st then cyclone
The quality is not the best. I have the V6 model and I love it, but a lot of cheap plastic.
Compared to the G tech, it's creaky tat really. I'm happier keeping the robot vacuum serviced now
The broken O ring still better than no O ring.
A drop of superglue will fix it. This is how custom size o-rings are made.
tanto..? gubbins..? Speak American, amigo!
B
Dyson = over rated & over engineered and apparently quality control is slipping.
I totally agree, expensive toys
mmmmmmm chocolate
Good gods, it's ugly.
Very nasty right? Imagine if the contract burnt itself loose and shorted the battery out totally! 💥
First
I am guessing you are not at work today: :)
