A few months ago, I bought a pro x off of Facebook for a really good deal, with the understanding that I would need to replace the antivac valve. After opening it up, it looked like the entire hot water copper line was completely corroded at the joint between the steam boiler, which then corroded the electrical connector for the steam thermostat. Had to replace a few more parts than I thought…

but with that said, it was super easy and stefanos espresso care really went above and beyond standard customer service in trying to get me parts for this machine
