Unfortunately, not yet. Still hoping, though!

To add to what I said above, I went through an elaborate process of priming as suggested here: https://ifixit-guide-pdfs.s3.amazonaws.c.... Same story. The steam wand works fine. Water will flow through the brewhead so long as the portafilter isn’t attached, though it isn’t especially strong., and I notice a leak from the side of the machine that runs down the side of the reservoir. When the portafilter is attached, nothing happens, though the leak is stronger. I’ll add that the portafilter works well on another machine, so no problem with that. Ideas?

I acquired a second hand Barista machine a couple of months ago that was exceptionally clean, not brand new, but clean. The pump draws water from the reservoir, and the boiler heats it up, producing steam from the wand, as well as hot water. Unfortunately, nothing flows through the brewhead. I have taken the machine apart, primed it (anyway, like I said, there’s no problem with the pump drawing water or the boiler heating it), decalcified the circulation system, and took apart brewhead to see if there was any obvious obstruction. There wasn’t. Any ideas?
