Dyson DC 37 Allergy Gasket change

Remove the Cyclone block from the rest of the vacuum cleaner (grey button on the motor)

Position the tank above a trash can or bag (open) then press the red button to release the bottom of the tank and empty the contents

Also remember to remove the fine dust filter which is simply inserted in the center of the cyclone block. It can be cleaned under the tap (see care instructions)

You will then separate the cyclone block from the dust tank

As can be seen in the first photo, the red slide that controls the bottom of the tank masks a small grey button

The second photo shows the fixing fangs (opposite side of the button) that solidify the cyclone block with the tank

A press of the grey button detaches the transparent tank from the coloured cyclone block.

A little rag on the outside of the cyclone block will be welcome before attacking it

Equipped with your torx screwdriver (star), you will be able to remove the 7 (seven) screws that attach the low skirt to the upper body

Set aside the seal that is attached to the lower part of the body and clean the

The lower part can be cleaned with a cloth and or water. It is possible to remove the skirt by sliding a thin tool to clear the hook notches, but this is not our goal today.

The body is now clearly visible and a new rag is needed in order to continue

You will now remove the cradle that houses the dust filter. This one is simply nested in the top block

It is necessary to gently unclip each of the 14 rings that enclose the cyclone exits

You can clean the cone as well as the inside of the top of the cyclone block

You must unscrew the last 7 screws using the Torx screwdriver

These are visible at the bottom of the block, between the extraction cones. It is likely that this part is very dusty and that you had to scratch a little to find them

Once the screws are removed, you can easily separate the cap from the intermediate block

A little cleaning is necessary

You will have to gently remove the joint so as not to tear it during the operation, especially if it is damaged

The cap is cut into 4 parts: the lid, 2 white pieces, one with moveable guides and the seal

Over time, movements and vibrations of moving parts have chipped and cut the seal

We see here the state of wear after fifteen years of good and loyal service

It is possible to make a temporary repair with adhesive tape to bouche and collect the pieces

Be careful not to obstruct the passages of screws or tubes.

The best solution is to buy a new one. They can be found on eBay for about ten euros.

You can see my repair here to wait for the spare part to arrive

All that remains is to reassemble with the new or repaired seal.

Don't forget to put the tank seal back on

That's it, good repair
