Im finishing a rebuild of a La Scala Butterfly and lost my disassembly pics.

Can someone tell me where the power (from the plug) connect to

There is one Blue, one Brown, and a Green/yellow (which I assume goes to ground)

Yes, you're right, the green/yellow is earth/ground.

The brown is live and comes from the fused side of the plug and usually would connect to the power switch on the appliance.

The blue is the neutral.


Just found this Click Here (www.bbc.co.uk) which may make it clearer.

Cheers

Ian

Good job, it sounds like your backflow prevention valves are sorted.  Now for the power cable, but I'm gonna need a hint...  
The eyelet is ground as you've guessed, so it's gonna be the copper bolt in the flooe of the machine.  The location of that bolt might be a clue. Is it right next to the main power switch, a fuse holder or the power board (Circuit board with relays in a black box)?  If your power switch is a double throw, it shuts off and on BOTH of the circuit wires (Blue and Brown), and from your photo they have push on connectors, so the switch will have two empty spade terminals waiting for them.  The other two terminals from the switch will also have a blue and brown going out to the machine.  I don't know your machine at all, so I'm just going by the fact that so far it looks like everything else is pretty standard so I'm giving a pretty standard answer from my knowledge of the Giotto which made me comfortable to answer the backflow valves and T question.
If my answer makes no sense, post again, and maybe a picture of the power switch, the fuse box if it has one and the powerboard (Hopefully a powerboard with a diagram sticker).  Cheers bud, and good luck.
