Just swapped a machine for this beastie, 2009 model Expobar 2 group volumetric 15 amp machine.
Couple of pics below, rough looking inside but it is maninly coffee grit/dust and oil.
So far I have powered up and the pump, heating element and right hand group seem to be working.
The left hand group electronics are working (and trigger the pump) but no water is coming from the group. Boiler is a massive 11.5 litres, bit bigger than I am used to with the domestic or prosumer machines I normally work on.
My test rig of a 15amp-10amp Ampibian and a cheap water dispenser pump fired up this machine ok, but I had to moved the pump to a different power point as it tripped an RCD as must have drawn over 10 amps.

Any thoughts on the left hand group not producing water? I am thinking physical blockage like scale in the copper lines.
I will have a look for a part manual or diagram and deciding whether I should do my first full strip down/rebuild or just remove the boiler and give is a descale and fix other bit and pieces.
