Coffee Appreciation

Right.. this fucking machine is in about 400 pieces.. there weren't even that many in the Gaggia schematics. :S

Anyway, it's not the copper pipe->grouphead arrangement, no it's more complex. The blockage appears to be in some kind of blue electronic valve thing which controls the water FROM the boiler TO the head and from the boiler to the drain pipe. Is this the OVP? The Over Pressure Valve?
Any of you pulled one of these apart before know anything about this shit? bombcup help!

Looks like Part 27 in here:
