Sorry but I've never seen a service manual for any of the M52's, which is part of the reason I sold off my M52 Station/Dolcevita some 10 years or so ago.

Yes, you are correct! It's the M52 Station/Dolcevita and weighs a ton! Thanks Javaphile for posting those, but I already have them in print. What I don't have is a service manual that technicians use. I'm seeking a service manual, I've done some service on it myself and been successful in diagnosing a problem, with just my personal experience and troubleshooting (no service manual). It was a clogged flowmeter valve, I forget where, that was a dozen years ago...
Now there is a problem which turned over control of the machine to a ghost. It's spookey and runs hot water on/off/on/off/on/off in random lengths, continuously. I'm guessing solenoid/relay replacement for that, any thoughts?
The main problem is that it's stuck in thinking it has not completed a 2 part grind/brew cycle. You can program it go brew 2 espresso's one after another, if you make these large doseage brews, it's like making 2 doubleshots (quad). It won't stop unless you turn it off.
Any help is much appreciated.

As there are multiple La Cimbali models called M52 for clarity I've split the existing documentation thread into 2 threads. One for the M52 that eventually became known as the M5 and the other for the M52 Station/Dolcevita. Yours is the M52 Station/Dolcevita. What docs we have for your machine can be found here: http://coffeesnobs.com.au/documentat...-diagrams.html

La Cimbali M52 (here's a matching pic: Ammirati :: Cimbali Super-Automatic Espresso Machines & unlike one in the manual at the top of this thread...) Model purchased in 2001, still in operation.
Has 2 small problems:
A: it's stuck in a quad shot espresso, in the secondary grind/brew phase, and repeats continously.
B: it intermittantly runs hot water through the hot water dispenser.
Searching for a SERVICE MANUAL if anyone out there has one.
I'm going to look at replacing the solenoid and/or relay for the hot water dispenser. But first, the machine is being UNPLUGGED for the night and plugged in, in the morning. Perhaps the cold reboot might do the trick.
** TIP: If you have this machine, you can enter engineering mode without the digital dallas keys by turning the machine off and switching DIP SWITCH 1, on the back of the mother board, behind the button panel. **
IMPORTANT!!! * * * You must have the machine OFF when switching this DIP SWITCH on / off. * * *

La Cimbali is very good about stocking parts for many years after a model is produced. Give your local dealer a call and they will be able to tell you pricing and availability.

There are several variations of the M52. All of them that I've seen require 2 different proprietary electronic 'keys' in order to have full access to all of their diagnostic and programming features. The last time I priced the keys I was quoted $USD1,000 for the two of them. Which is about what I've seen many of these machines sell for in working condition. In spotless as-new condition, with the keys and a warranty I've seen them go as high as three to five thousand USD.

I basically got this machine as a bit of a project to tinker around with. I have no intentions to use it at home as it is way too big, I was thinking I could get it up and running and then sell it to fund a better home espresso machine.
What would a good condition M52 fetch on the market if I get it up and running?

First thing I'd look for is anything interfering with the mechanism with the next thought being dirt and/or corrosion fouling it.
May I ask what your intentions are for this machine if/when it's working? For a number of reasons these machines work best in high use environments and for a snob would be horrible in pretty much any setting.

Nice docs. I've combined the two M52 threads and edited the title to reflect the additional docs.

Respond as in write here then just start a new topic in the documentation thread or add it to the other m52 doc thread?
