A friend of mine got a 2nd hand coffee machine (OK, probably 3rd or 4th...) for use in a charity cafe and it has problems.
First problem is no manual or any other useful information! The power cable is 4 core brown, black, blue, green & yellow so it looks as if intended for two of a 3-phase supply. I tried it with brown & black on to a single phase 13A plug arrangement in the hope it was just for load sharing, but nope - not heating of water but display lit up.
Then I ran in a very basic arrangement to have two phases to the machine and lo! Water would heat, but now no display either way (going back to single phase, etc).
My suspicion is the thing is gubbed, but if anyone has knowledge of it or an instruction or repair manual it would be greatly appreciated.
TL;DR help for a 15-year old La Rocca machine
