Bezzera Aria - heat exchanger espresso leak fix

Fixed a small pressure leak at the top of the boiler where the boiler connects to the OPV. After fixing the leak I determined the leak probably could have been fixed just by tightening the bolt a little. But going through the whole flow of removing and cleaning has yielded a very good result. The leak is fixed and should last for a long time.

I wish there were more channels highlighting this machine. I’m selling my Ascaso Duo so I can pick up an Aria. The duo has no flow control and I really want a machine with flow control.
