Hello, and thanks for the great teardown! I'm just getting into my non-functional Barista unit, and wonder if I could "borrow" your expertise! I have cleaned EVERYTHING, all seals are good, and replaced the pump (probably in haste). I cannot get water to come out of the brew head. From your other posts, I see that it may be either a clogged valve (cleaned it already) or not enough pressure in the boiler. What else can I do to to get water from the portafilter, or build more pressure? Is it electronically regulated somehow? Thanks for any suggestions!
