This is how I use a pocket mirror to see the bottomless portafilter and the pressure gauge at the same time from in front. (The Cafelat cappuccino cup has my half finished drink in it - this photo is just for demo purposes. Normally I am pulling the shot into the empty cup.) {image}

I'm lucky in that I think I have at least one top notch roaster that is local to me (who has the lion's share of my coffee purchasing), as well as few other quality ones easily available. Original Portland is a very food focused city, and as a result more and more restaurants and cafes are constantly opening up and offering coffee from well respected national roasters. Just off the top of my head ...

Regarding the GS3 parts catalog - found this link: https://www.lamarzoccousa.com/wp-conten ... _COLOR.pdf So all set there.

When it was the last time you took it apart, cleaned etc? (and how comfortable would you be to take it apart?) That I see in the pic in that one there is no 3way, this means you have a group valve behind the shower screen (take screen off, if I remember correctly your model has the screen holder which you also take off, the gizmo in the center of the grouphead is the valve) If that one is in any w...

Hey folks. I have been having issues with low flow rate with my GS3 AV. I used Peppersass recommendation to calculate flow rate and it turns out it is running about 60 ml/minute using the formula from this link: La Marzocco GS3 low brew pressure problems I followed Chris Coffee video (thanks Chris) to drain the brew boiler, open the group head, remove the solenoid valve and pull the TL-30 tube out...

There is some variation in Breville flow rates. My guess is your older machines pumped water closer to 8 ml/s and your newer one is closer to 6ml/s. Lower flow means a finer grind is needed.

I know for certain that one of the best ways to ruin a shot is to Putz with flow or pressure during a shot. Pressure or flow profile has a material effect on your output. I'll try Sam's method of lumbering over the Cafelat like I'm shielding it from gun fire and see what I can muster. Lol I think I'll remove the gauge from the arm since it hangs in such a way that I'll be able to see it if I'm in ...

I find the gauge useful for exactly this reason. I do not believe that it is so easy to know you have constant pressure without it. Necessary? No... Optimal? Well... if I do: a) a nice 2 bar preinfusion until coffee is dripping evenly from the entire basket bottom (assuming I distributed and tamped well), then b) ramp up to 8 bars and hold that for 50% of the shot, gradually reducing to 6 bars by ...

Does anyone know exactly what the difference is between the Regolare 600N and the Feima 600N? They look practically identical. I know the Regolare 600N is stepless, but I don't know about the Feima (there are other 600N type grinders out there that are not stepless). Does anyone know if it is stepless? Also, what kind of burrs does the Feima come with? Thanks for the help!
