I have a Bezzera BZ07 - HX machine, non-plumbed, vibe pump, about two years old. Recently my three way function changed dramatically - water to brew head pretty much as normal, but not the normal relief to drip-tray (used to be a nice strong whoosh) and I do get occasional dripping from the drip-tray valve during extraction. I went through the typical steps...took everything apart, soaked, scrubbed etc. to no avail. But I do notice some minor denting and degradation of the green rubber ends on the nucleus inside the vertical plunger tube.
For this machine, one has to purchase the entire assembly...solenoid, valve, plunger, nucleus. I would do that, but it seems to be on indefinite backorder. So, I'm thinking about finding another brands part and adapting it...any thoughts as to what i need to consider would be appreciated.

I can not direct you to any specific part but often the parts are interchangeable or nearly so. I swapped a lot of new parts into a Sylvia from a entirely different brand of machine using different manufacturers of parts, and with the exception of the wires being on the opposite side of the coil, the 3 way was identical.
