This undisputed king of the espresso machine world was too good an opportunity to pass up. I had been nagging a
restaurant group for ages to clear some of their stock of used and abused machines. A Nuova Simonelli was
offered to me which quickly became a NS Mac, this Linea and a Cimbali super-auto. I knew that this machine was in
working condition which was a good thing but if you are going to do a complete and utter restoration this does not
really matter that much since all components would be stripped and overhauled. But still it is nice to know that
everything is operational and almost all of it can be re-used.
At this point I sort of had an idea of what was in store, this was one machine that had been neglected and never
cleaned, ever! You can see the dirt on the pictures which was an oily and slimy and left a film on practically
everything. One thing I cannot get accross was the smell, the machine had a very bad stale odour, it may have
been the oil or it may have been the dead insects from inside, and there were many of them. One of the first jobs of
any restoration is pest control.
With the main panels off it was just time to start pulling it apart and dropping almost every nut, bolt, screw and
component into a bucket ready for cleaning and descaling. I can pull apart and assemble Lineas in my sleep, but if
it was any other machine you can be sure I would be taking mental notes as well as photos to make sure I knew
where each part went to make assembly that bit easier. I don`t think that there is any real method to dismantling a
machine, just work from the outside, usually the boilers are the last pieces to come out, once they are out the frame
can come apart ready for cleaning.
|A nasty surprise
The brew boiler was in a bit of a mess as you can see above. Usually with LM machines the steam boiler is in a
worse state in terms of crap and scale build-up. I attribute this to the fact that the water does not get replenished as
often as the brew boiler and therefore sediment is allowed to settle. Now I usually expect the steam boiler to be a bit
worse then the brew boiler but I have never seen anything like this....
Pulling the machine apart was not too long, about 1 hours including time for photos. I like getting this part over and
done with because it is so grubby and dirty. The smell I cannot stress enough was awful.
