Replacing a Miele W864 Front Loading Washing Machine
Door Seal.
Extracted from an Internet article by one Neil Lewis (2007) & updated by A.D.King after an actual installation on 30-Jan-2010.
Having just done this on my own Miele W864 (A.D.King) (but virtually all Miele front loaders are similar in this respect says N.Lewis, in particular the W700, W800 and W900 series).
I recommend that only a genuine Meile replacement seal is used. After market rubber parts are not to be trusted. From experience of car parts e.g. CV joint & gear lever gaiters etc, they just don’t last. The composition of the rubber is wrong, so they harden & split in a much shorter time (say 1 year against 5-10 for the genuine item), so is a false economy, especially as this is not an easy job for an amateur. You won’t want to repeat it too often.
All procedures carried out are at your own risk of course. If you do not feel that you are competent – then get a professional engineer to carry this out.
All parts listed except for the seal obviously, are reusable.
Tools required are described within the text below.
The procedure to replace the door seal is as follows : -
1. Open the glass door & pull the machine out from under the worktop, then turn off its electricity supply by unplugging its power lead from the wall.
2. Either side of the top panel towards the front are 2 x white blanking caps. Carefully prise these off using a knife blade or similar. Remove the 2 x revealed countersunk Pozidrive screws using a small Pozidrive screwdriver. Lift the top panel & slide it back a little to free the Control panel & Soap box receptacle mouldings which are attached to the front panel. Or just take off the top panel completely, there being no other fixings other than two locating lugs at the rear.
3. Completely remove the powder dispenser drawer (it will come out so far and stop), then there is a small red button at the rear of the dispenser which you need to depress to remove it fully. You'll see this button once you've withdrawn the drawer to its stop position.
4. Now look at the front aperture of the Soap box receptacle (you have of course removed the actual drawer earlier). Remove the 3 x Torx socket screws using a size T-20 Torx bit (two either side of the aperture & one recessed in the lower LH corner).
5. Using a 10mm AF hex socket bit (if I remember rightly), undo and remove the 3 x stainless steel hex head bolts, equispaced around the chassis door seal. Note, these bolts actually secure the front panel to the machine chassis; they do not retain the door seal. So don't worry, the front will not drop off.
6. Open the square pump access door (lower left hand side of the front panel) and unclip the drain tube from its plastic retaining clip.
7. Now, you'll need to get on your hands and knees. You DO NOT need to tilt, or lift up the washing machine to do the next bit. Locate the underside of the front panel right at the bottom. You'll notice that it sticks out about half an inch or so and is proud of what I would call the kick plate which extends right down to the floor. You need to look on the underside of the front panel, about an inch or so in from the left hand edge. There you will see a spring loaded clip, which when closed, locates into a slot in the underside of the front panel. Using a stubby (short but chunky) flat bladed screwdriver, you need to carefully lever the spring clip down (to open) whilst gently pulling the whole front panel (from the left side) ajar. It will just suddenly pop out once you've done it.
8. Now carefully swing open the whole front panel. It opens like a door (hinged on the right hand side). It might be a little stiff as there are a host of leads attached to it, but it is designed to open fully (with the leads attached) to about 90 degrees.
9. Next, unseat the old rubber door seal from around the chassis aperture (door opening area on the chassis, not the front panel, obviously), so that the seal flops away from the chassis and lies just inside the machine.
10. You will notice that there is a steel round wire clamp band, holding the door seal in place around the outer static drum. On the right hand side at about the 3 o'clock position, you’ll see its tensioning screw. It’s tricky to get at & requires patience. You will need an angle drive (offset) screwdriver (e.g. Spec Tools - SkewDriver Pro http://www.spectools.com/ available from Amazon etc) for efficient removal & especially re-installation, with various length extension pieces. Power it with an electric screwdriver because the screw is very long & will take all day by hand with much swearing. Undo the screw using a 7mm or 8mm AF hex socket bit (I can’t remember which), to the screw’s max length. Try to avoid completely disengaging it from its special clasp nut, otherwise this nut & the screw’s under head plain washer will fall down into the machine. If so, locate these and retain them for later.
11. Now remove the steel clamp band by extending it to its maximum opening by moving its 2 x lugs apart. Then pull it out through the hole/door aperture in the chassis.
12. Locate the seal’s small rubber tag at about the 12 o'clock position, where the seal is attached to the outer static drum and carefully tug it. The seal will then come away from the drum. Remove the old seal completely.
13. Carefully clean around the inner rim of the outer drum to remove all trace of old soap sludge & any limescale using a suitable cleaner e.g. Viakal Limescale Remover. Lime is most likely to be found at the bottom of the rim. Clean to a depth of about ½” (finger tip depth).
14. Using your new seal, place this correctly around the drum (there is a lip on the seal and this has to go over the rim of the outer static drum. Ensure the 'tag' is at the 12 o'clock position. The seal goes over the outer drum surprisingly easily & can come away quite easily to, whilst struggling to refit the clamp band, so keep checking it’s still in position.
15. If you need to reassemble the screw into the clamp, note that the clasp nut has a chamfered corner side & a square cornered side. Ensure the nut straddles the clamp band’s round lug, with the nut’s chamfered side oriented inner most, so to prevent it cutting into the soft rubber seal.
16. Feed the assembled clamp band through the chassis & over the new seal so the screw is again positioned at the 3 o’clock position with the screw’s hex head at the top. Ensure the clamp band is located right at the back behind a little raised ridge in the seal. Check this is so all the way around. Tighten the screw in stages, rechecking the bands position each time. Power the electric screwdriver using the hex socket bit with one hand whilst holding the wire clamp band in place with the other. This is fiddly, so take your time.
Warning – get this wrong & you will flood the kitchen floor.
Warning – do not be tempted to use the optional slot in the screw, because a flat driver bit can easily slip out of the slot (guaranteed to) & will most likely stab & puncture you nice new expensive seal, rendering it useless.
Make sure that you do up the clamp band sufficiently. If you find the screw does not seem to be getting tighter in relation to how closed the clamp’s lugs are to each other, then the wire band has probably come adrift, so check before any damage is done.
17. Carefully pull the seal onto & around the front chassis aperture. When correctly installed, there should be no obvious stretching, twisting or wrinkles.
18. Reassembly of the Front & Top Panels etc is then the reverse of removal.
19. Finally, once you're done, put the machine through a few rinse cycles (where the water level is high) and look for leaks. If you have a leak, it is likely that your door seal has a rip/tear, or that it has not been correctly located around the drum - in which case you'll need to investigate.
