Re: miele W844
think i know which one you have got and if i am right do the following
there should be 3 x 10mm bolts in the door opening if there is undo these
pull out soap draw, undo 2 torx 20 screws either side of soap draw opening. undo torx 20 screw soap draw opening left hand side. open filter housing and unclip plastic drain tube
the whole front of the machine will hinge out after unclipping metal clip at bottom left
now remove kick strip ( 2 screws)
unplug motor and remove outer cover ( 2 screws )
undo the rest of the screws on plastic plate on rear of motor. carefully remove and you have access to the brushes
when you refit brushes are captive in holders. after fitting you have to push something down the brush tubes and push till you hear brushes go click ( i use a small allen key )
plug it all back in and away you go
its a bit tight getting covers off and back but can be done with care
hope this helps
