ECM Giotto releases steam instead of water from the coffee group
My ECM Giotto has worked perfectly for about 8 years, with some minor services and replacements. Now I have come across a problem that I don't know how to fix. The machine starts, pumps and gets hot. The steamer works, the water from the water tap is hot, but when I try to make coffee just a few drops of water comes out of the coffee house, and then there is only steam coming out. I have tried to drain and refill the machine multiple times, but it won't solve the problem. Once the steam comes out of the coffee house, and the pressure goes down, the pump starts, but it don't seem to refill the reservoir and stays on forever, unless I turn the machine off. If I restart the machine after an hour or so, the pump works again, refills the reservoir, but the problem is still around...
Would very much appreciate any input!
All the best / Jakob

Check the shower screen and diffuser in the head, they might be blocked, if not, check the metering jet at the top of the head(large nut) CAREFUL, make sure machine is off and cool before removing, use a paperclip or pipe cleaner to clear blockage. If not blocked then you will have to check the brew solenoid.
