Dyson DC 37 Allergy Gasket Replacement

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

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).

Next you will separate the cyclone block from the dust tank

Press the grey button to detach the transparent tank from the colored cyclone block.

Wipe off the outside of the cyclone block before tackling it

Remove the 7 (seven) T8 Torx screws that attach the lower skirt to the upper body using a Torx screwdriver

Remove the gasket attached to the lower part of the body, clean it and set it aside

The lower part can be cleaned with a cloth and/or water. It is possible to remove the skirt using a thin tool to release the retaining notches, but it is not necessary for this repair.

The body is now clearly visible. Get a new rag before continuing

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

Once this operation is done, simply remove the cone by pulling it to extract it from the socket

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

Unscrew the last 7 screws using the Torx screwdriver

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

A little cleaning is necessary

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

It is possible to make a temporary repair with adhesive tape to seal and reconnect the pieces

You can see my temporary repair here while I wait for the replacement part to arrive

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

That's it, well done
