MediumRoastSteam As an update, I’ve run the machine all day today in normal (non auto-standby, non-eco) mode, 93C brew boiler, 130C steam boiler, and it seems stable between 92C-94C. I haven’t stared at it all day, but I’ve walked by it maybe a dozen times and it’s always been within range. Maybe it really was just pushing the steam boiler too hard that was causing the weird brew boiler behavior. Fingers crossed that’s the issue, 1.7 bars of pressure seems like more than enough for my needs.

Also I can totally relate to going overboard with tweaks right from the get go. The first thing I did was drop the pressure to 9 bars, which seemed pretty important, but I should really work on getting consistent dialed in results before I start messing with more things (obviously going to be impossible until my Niche arrives, hopefully soon).

      Glad to hear it. This is a great machine.

      Is there a way to mod the Elizabeth hot water knob to be used for flow control, similar to the Slayer Mod for the Breville/Sage Dual Boiler? The Elizabeth is otherwise a more attractive machine.

        Ah, good point. I see it only has a steam knob. What happens if you open it during espresso extraction?

          Boren - nothing. It’s a dual boiler. You’ll get steam, and you can steam and brew at the same time.

          If you go to “About” in this forum, there’s a link to many coffee machine reviews, including the Elizabeth, in great depth. You might want to take a look. 😊👍

            Interesting. So I finally have some justification for owning two single-boiler espresso machines over a dual-boiler one :-)

            gobucks . I haven’t stared at it all day, but I’ve walked by it maybe a dozen times and it’s always been within range.

                -Mac LOL. Pretty accurate. Anyway a few days in, so far, so good. While I can’t explain the exact mechanics of it, it def seems to be related to running the steam boiler hot. At 130C I have no issues, and it’s plenty of steam.
