Well it broke on Tuesday, I figured out it was the Flow Meter lid, found it on Espressoparts.com and it arrived today. (Can you tell I just downed a double.) I am psyched, the guy that worked on this machine before we bought this business was overpriced and a bit of a jerk. So I was bound and detdermined to do any repairs ourselves. So far we have changed out the grouphead gaskets and screens and now I made this repair. I feel invincible. The machine was making a horrible racket (kinda like a high pitched whine) occasionally and now we know why. It was probably pressure leaking out of the flowmeter lid. So I just wanted to brag. . .and we had a huge group of bicyclists in here last night all wanting of course, Espresso. Oh well I just wanted to tootmy own horn. . .bear with me as I bask in my glow!!
