I purchased this machine used, so I don’t have all the previous history on it. The pressure regulator membrane and accompanying o-rings were replaced a couple months ago, as there was a leak. It is now LEAK-FREE and functions properly. I’ve cleaned it as best as I can, but there is still some dried hard water residue in the reservoir, and the water filter should probably be replaced. Aside from that, and some scratches/scuffs from normal use, it looks great. Please feel free to ask me any questions.
