I've owned my Expobar Office Lever for over six years now and I am still mystified as to how to produce consistent quality shots. I have settled on a great coffee roasted by a local roasterie and have been experimenting with a variety of grind fineness to get the proper duration. I have purchased a porta-filter pressure guage and adjusted the OPV to provide the correct shot pressure. I "temperature surf" by flowing water prior to pulling a shot. I have adjusted dosing amount and tamping pressure. I only make adjustments one at a time so I can narrow the variables. After all that I only produce an exceptional espresso about 1 in ten times. It is agrivating, but I guess the real question is why am I able to produce the best espresso I've ever tasted every once in awhile? I'm trying to develop the ability to determine "sour" from "bitter" so I can further diagnose the problem. What else can I do to diagnose what I am doing wrong? What might I be doing that needs to be corrected?
Do you own a grinder and if so which one
After replacing the gasket on my 2004 Silvia, it is very leaky and the portafilter twists way past perpendicular when pulling a shot. I'm sure I have the correct gasket. Has anyone experienced this?
Check and make sure the beveled side is down. If not it could be the problem
Have a Silvia,the manfacture date is 12/05 Not sure if it's V1 orV2 Will this fit?
This one will definitely fit!
Just wanted to make sure this gasket fits the Rancilio Silvia V3 before I order....
This is the correct gasket for your machine.
