Just picked up my first rebuild project. A non-working Rancilio Z11 Omnicron II.
The following threads look like they will be of some use.Please help power a Rancilio Z11Rancilio Z11 Rebuild
I'll have some photo's up tonight when I get home, but all and all, it doesn't look to bad.
The good things is that it 'was working' about 2 months ago in a retail shop, but then died due to an electrical 'spark' according to the previous owner. Now it just trips the breaker whenever it is turned on (probably a ground-fault somewhere). It appears the unit hasn't been frozen (since I picked it up from the shop, and the shop hasn't been below freezing). And the boiler is holding some reserve water that I need to drain, but at least it doesn't leak with the water that's left in it, it the machine.
Now, the inside of the boiler is probably in BAD shape, even though the previous owner said it was 'cleaned regularly' I doubt it was fully re-furbished then cleaned regularly, so the boiler is probably in some really bad shape. Also a few spot-leaks have produced some crystal-rock looking mountains on two of the connections going into the boiler.
Two quick questions now.
1. Anyone have a link to the service manual? (Rancilio's website seems to have taken down there old service manuals.)
2. Anyone have a link to a method on removing scale on a chrome boiler?
Thanks in advance.
Finally... thanks for inspiring to take on this crazy project and welcoming me to the forum!
Wouldn't have been so thrilled to try this without all of you having this wonderfully addictive CEAD disease (Coffee Equipment Acquirement Disorder)
