Miele S512 - Polish up and Refurb!
« on: February 04, 2019, 10:11:15 PM »
A fellow collector and good friend called HooverMaster asked me for some help last year with a Miele of his that needed a bit of sparkle, and I was only too happy to oblige! So, in came a box

Not a valid youtube URL
Which contained a very dull vacuum (dull as in finish, not as in to use!)

ila_rendered

Now I didn't get the wand, and for good reason as all I can really do with them is rinse it off and give it a wipe down, but they suddenly make packaging a much harder job, so that was not sent. The ratings plate had taken a battering too

ila_rendered

The hose end was included, so that gets stripped down a bit to wash

ila_rendered

On this generation of Miele hose end, 1 screw holds the clip part on

ila_rendered

and it simply pulls off, so you can clean it all out properly

ila_rendered

Mr HooverMaster has cleaned the machine out already, but forgot to re-fit the motor sound deadening, which was fine as the machine needed to come apart again to polish so I didn't catch the black plastic, so could be refitted

ila_rendered

The floor tool was quite clean, but could do with the extra pep, so we remove the rear wheel which joins the 2 parts together via it's axle

ila_rendered

ila_rendered

The locking tab pops off, fluff usually gets behind these with age

One of my bugbears with Miele is how bad the baseplate on the floor wears, luckily this one is spotless

ila_rendered

Screws out and it's VERY clean under here, someone has been here before I think!

ila_rendered

The lint strips pop out of the baseplate

ila_rendered

The brushes lift out

ila_rendered

AHA! Dirt! (not fully worth all this effort tbh but


The clip that holds the suction duct to the floor head unclips

ila_rendered

And the pedal assembly unclips, uncovering yet more filth!

ila_rendered

The suction duct can be lifted out now

ila_rendered

And the floor head is apart

We can move onto the vacuum cleaner itself now, and this is such a lovely shape of cleaner, and a lovely colour of Corn Yellow

ila_rendered

Popping the tool cover reveals some tools, which is nice

ila_rendered

And some more dirt

ila_rendered

There's such a severe lack of shine, it's a bit weird actually, vacuums are never usually this bad, I think it was frequently wiped down with something abrasive throughout it's life...

ila_rendered

Tools out

ila_rendered

Pulling the brushes out of the dusting brush reveal some hidden fluff

ila_rendered

The spring that makes the tools door pop up can be removed
ila_rendered

And the top layer is empty (remember what I say about Miele? Layers!)

ila_rendered

Time to remove the very recent and pretty empty bag (which I re-fitted, because it's fine)

The post motor filter is again very recent, so got a quick wash with the rest of the parts just because, but is in no need of replacement

ila_rendered

Pre filter is just as clean, and I didn't bother doing anything to it at all

ila_rendered

We can now remove the bag door itself

ila_rendered

And remove the hinges, which rotate until the little notch lines up with the cutout, then they pull out

ila_rendered

Under the bag door is the hose inlet cover

ila_rendered

Which is clamped down with this plastic part here

ila_rendered

Then the hose bit just lifts out

ila_rendered

Which splits out even further!

ila_rendered

The bag door latch springs with this HORRIBLE spring, which was already not fitted correctly

so off it came

ila_rendered

The blanking plug for the powerhead models pops out, and stops polish buildup in it's crevices

ila_rendered

The tool door latch and bag full indicator can come out now

ila_rendered

The latch part pulls off the indicator

ila_rendered

And the indicator pulls apart itself

ila_rendered

Onto the business end now

ila_rendered

One screw and the whole panel lifts off the machine and the wiring plug

ila_rendered

The wiring loom can be removed from the cover now

ila_rendered

Power control knob removed from the panel

The pedals unclip from the centre part

ila_rendered

Then the middle part can be unscrewed and lifted off the base of the machine

ila_rendered

The post filter cage can come off

ila_rendered

Now this is why I wanted it apart. I'm only being paid to polish this and fettle the motor, but it has to come apart like this anyway for polishing, and I can't leave all this carbon grime here!

ila_rendered

With this out of the way, we can see the business side of things, and gosh that motor looks like it's been damp before...

ila_rendered

The cord reel lifts out after removing one screw

ila_rendered

Motor and dust bag seals out

ila_rendered

We'll look at this later

ila_rendered

The base is very very clean though! Makes a change from my usual fodder

Bumper and associated off

ila_rendered

Bag holder out

ila_rendered

Wheels off

ila_rendered

Wheel holders off

ila_rendered

I can get at the pre filter cage now, which just pops out, although I couldnt see that/forgot a bit earlier

ila_rendered

A random bit of metal... never seen this on one before

ila_rendered

All that went off and was washed, and got cosy in the airing cupboard. Time to see to the motor

ila_rendered

Fancase off

ila_rendered

Fan off

2 screws under here hold the base of the fancase on

ila_rendered

ila_rendered

The VERY manky PCB was removed, oodles of water damage on here

ila_rendered

And 2 long bolts from the other side hold the rest of the motor together, and it all falls apart like so

ila_rendered

I washed the motor casing, so was left with a pile of bits.

ila_rendered

New bearings (608zz's, like our host is now selling for Sebo motors) were fitted to replace the utterly trashed ones

ila_rendered

The top one fits to the motor housing itself, and just pushed in nicely once the corrosion was cleaned up

ila_rendered

The fancase one needs fitting to the armature itself, deep sockets and a hammer help here!

ila_rendered

Then the comm was cleaned up, and everything re-assembled after a good fan wash, it spins silky smooth now

Then, the magic happened

ila_rendered

ila_rendered

ila_rendered

and although not 100%, it was a vast, huge improvement!

Now we can do the usual

ila_rendered

And nail it all back together! Wheels first

ila_rendered

A little drop of grease is key on these, makes it run so much smoother

ila_rendered

Fitted!

ila_rendered

Possibly critical bit of metal fitted

ila_rendered

Pre filter holder fitted

Bumper re-fitted

ila_rendered

Bag holder

ila_rendered

fitted

ila_rendered

The front handle finishing trim is fitted

ila_rendered

Sound deadening back in

ila_rendered

Motor in

ila_rendered

Seals in

ila_rendered

Then it all went a bit wrong for the cord reel. See, it was a bit lazy, so I gave it a little tweak and PIIING, it broke itself...

ila_rendered

Which is game over really, so annoyingly I ponied up 20 for another cord reel... Which never showed up, so I got a refund for that one, and ponied up 17 for another one! We can see the inner workings though, and it's a shame these gum up so much because you cant get them apart to clean short of having to re-tension the whole thing, which you cant really do without a jig to hold the spring

Some time passed (actually no, I just carried on and fitted the cord reel when it arrived, but for the sake of this thread, you've fitted the reel back in by now!)

So, top cover back on

ila_rendered

The wiring was fitted, and the control panel was fitted to the cleaner with it's 1 screw

ila_rendered

Post filter holder fitted

ila_rendered

The bag cover was hidden inside the machine (they can fall into the void) so that sat under the TV unit for a day to flatten it out, and was fitted along with the hose inlet assembly

ila_rendered

to the bag door

ila_rendered

The bag and filter went in next

ila_rendered

Then the 2 yellow parts were bought together

ila_rendered

Tools in

ila_rendered

And tool door on

Looking much better now!

ila_rendered

Floorhead now, suction duct back in

ila_rendered

Pedals on

ila_rendered

Brushes, springs and baseplate on

ila_rendered

And the tool clip, although not when this pic was taken!

Here is a cord reel, finally! I left it the hell alone and just fitted it, it worked very well!

ila_rendered

ila_rendered

Post filter in

ila_rendered

And gosh, after a few layers of this

ila_rendered

It's DONE!

Now, sadly, after all this the motor REALLY was not very healthy


Which is a shame, but, Hoovermaster, ever the gent he is took it on the chin, and got hold of a much better motor, which was the easy part really, and transformed the machine, and (unless he's fibbing to save my feelings) was really chuffed with how it turned out!

As was I!

Great thread as always. Yeah the motor only lasted a few minutes really but a replacement was obtained, as well as an original style head and much better tube. The bag catch was replaced which has made it work better now. And loads of minor tweaks have made it perfect. Has cost me loads but great to preserve machines like this!
