I have a Dyson I took out the screws to clean it before I opened the canister now I can not get it together again

How to Repair Dyson vacuum cleaner
Try using the link below to address your problem.

Just had the same problem. Took apart whole power head to look for broken wire and found none. If you see part way up the hose there is a coller with 4 torx screws holding together. This collar is a swivel that allows the hose to spin without twisting or kinking. Take the 4 screws out and open up. You will see 3 contacts that look like fingers that rub on 3 mating steel rings. Wipe the tips of the fingers and wipe clean the rings. Gently bend the fingers out wards so that they apply more pressure to the steel rings. Reassemble and try. Should take no more than 15 mins. Worked for me good luck!

sounds like your belt is worned out its not gripping i suggest change belt have it replaced

I'm not sure about all the switches used in the vacuum, but I recently took some pictures of the power button assembly. The buttons in the picture below are (from left-to-right): Circuit Breaker, Brush Switch, Power Switch



The next picture shows how the plastic buttons that operate the brush and power switches should go together:



And finally, this is how the power button assembly reattaches:

DYSON DC08 ROOTCYCLONE Loss of suction problem.

I had this exact problem and solved it.
No offense to Dyson Customer Service, but that advice isn't nearly enough to explain how to clean the cyclone. I used to work in Customer Service for an electronics company and I never let anyone down because of clear and precise instructions.
So, here is my advice:

NOTE:
Remember properly where all the screws go and how the bits fit together. It's important so that there is no loss of suction due to improper replacement of parts.

Step 1
Remove the canister from the vacuum cleaner and take off the clear bottom bit - the container for dirt. Clean that out well, you can use water but MAKE SURE IT DRIES COMPLETELY.

Step 2
Pop off the conical bit at the bottom of the cyclone. It isn't held by any screws, just nudge it out of place.

Step 3
You will see three holes amongst the vacuum entry holes. These three holes have screws in them. Unscrew those.
The type of screws used are star-like, but I used a small flat-head screwdriver. Make sure the edges of the flat-head fit perfectly into the edges of the slot on the screw. This prevents grinding and damaging the screw.

Step 4
Turn the canister over, the grey handle conceals three screws. Two on top and one beneath the bottom of the handle at it's base. When you remove the two screws that are visible, you can gently pop off the handle from the canister. First pull the handle up slightly, then the hook unlocks at the base, then push the handle away from the air inlet hole.

Step 5
Turn the canister over again. The bit where you removed three screws should come off easily. Beneath that, you will see two more screws, holding the top bits together. Remove those screws.
Then, all of the cyclone is loose and you can clean each bit separately. Again, you can use water, but let it dry very well.

Step 6
Put it all back together.

Hi its Darran at Dyson.

The screws on the base of the cleaner head should not have to be removed to access the brush bar so it is possible that the brush bar has come out of alignment, hence the noise the machnie is making.

Please ensure that the soleplate has been correctly positioned and that the brush bar is aligned correctly before attempting to use the machine.

If this does not resolve the problem, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

Kind regards

I love the Dyson (DC07), but after 7 or 8 years it lost suction and needed some attention beyond filter cleaning. After much online research I found the few bits of advice that for me were the holy grail. After all of the standard stuff, clear clogs, clean filters etc..... In this order: 1) Remove & empty the canister, ***important****-leave the canister bottom lid open. 2) remove the three star screws at the top of the canister. It'll take a bit of pressure to pull the top up, there's a rubber seal. When you pull it up there will be a rod running down into the canister, leave it be, just pull up the top high enough to clear out any debris. 3) Put the top back on aligning the screws, when you lower it make sure the bottom of the rod engages with the hole at the bottom center of the canister, this is why you left the bottom lid open. Put the three star screws back in. 4) Turn the canister upside down, lid open, and keeping in mind this is thin plastic, gently tug upwards on the four fins that surround the bottom rubber seal. This part is held in by friction, so work your way around the four fins gently pulling until you work the ring they're connected to free. This will give you access to the inside of the canister. 5) remove the round perforated section by tugging upwards on it, set it aside with the fin part. 6) Take the canister to a laundry tub or large sink and holding it bottom up fill it with hot/warm water. Grasping the center section shake it vigorously and turn it upside down while shaking and a bunch of sh*t will come out. Repeat several times. 7) Dry thoroughly, you might use a hairdryer held to the center tube, but only if you can switch off the heat and use air only. Make sure its 200% dry, water will kill your machine 8) clean and replace the round perforated section 9) replace the fin section, I'd suggest pulling the round rubber part off of the fin part and setting it in place on the canister first, then follow with the plastic fin part. If you don't do it this way the rubber won't seat properly and the bottom lid won't close. 10) Close the lid, replace the canister, and staaaaaart suckin like it's brand new.

The electric motor inside your Dyson has a built in over-current trip to protect itself (and you if it seriously overheated and caught fire). This normally automatically resets itself, however if the motor has just about had it, next time it is switched on it just trips again.

The primary cause of motors overheating is that the filters are not cleaned or replaced frequently enough. Dont be fooled by Dyson's "lifetime filters". They need to be regularly cleaned and replaced when necessary.

Replacement motors are avaible on eBay for about £25, however repalcing one requires good DIY skills and tools.

Have a look at www.dysonmedic.com and see if you feel you can tackle it yourself. If not, take it to a repair shop or call the Dyson helpline.

I've done that.
There is a stem that runs down the center of the cyclone that releases the bottom. You didn't get that stem back in place. The only thing you can do is pry it open, hope is doesn't break, and put that cyclone back together correctly.

I've never broke one, but I had to pull pretty hard. Thought I was going to.

Good Luck
