Coffee Appreciation

That's if you're lucky, I was pulling handfuls, probably about 2kg, of limescale out of mine.

My first thought (not having looked at that diagram) is the multi-core is optional 3-phase, the 13a is for the pump, as the element runs close to the capacity of a 30a cooker circuit and an espresso pump starts with quite a whack (hence the big capacitor they have on the side) and could trip the breaker, though I can't see the pump - is it external?

The drum thing is the power switch - position 1 for all the systems, position 2 includes the element.

The wiring may well have been modified over the years. You need to take all the casework off and have a good look around and check it against a proper diagram.
