Thanks for your reply. I was comparing to one thread here that has quite a few plots "Lever Espresso Machine Flow Profiles" I am trying to mimic the LM leva with slightly longer 9 bar dwell to accelerate the initial flow rate increase But at the same time, I think my flow rate will not be as flat

Hi all, After 4 solid years of use, my Dual Boiler has started to give me some grief. The machine is taking longer to build up pressure, and is not getting to 9 bar. When it started happening, I descaled and cleaned the machine and it worked well for another few weeks, but it is now back to the

If this is new unplug it and contact Rancilio. If it is used unplug it and have a qualified electrician look at it. Things that trip GFI can cause bad things to happen

Hello! I was sent here from Reddit. I purchased a Rancilio Silvia last week. When I turned it on everything seemed to work fine. I flipped all the switches on, pump was work, water came out of the group head but as soon as I opened up the nozzle for steam, it tripped the GFCI outlet. It seems like

Huh I'll chalk it up to a gap in my knowledge but since I'm not the only one with the 'issue' I'm guessing MiiCoffee/Turin are going to get more people who also don't know this! Thanks!

Drain the boilers from the front screws completely. Then turn on to let warmup and refill steam and brew boiler, let it sit at temp a bit before using. Might be air in system or wasn't correctly filled somehow

Always run the motor when adjusting finer. It's common practice even with much more powerful commercial grinders. It's also what Joe Kolb from Espresso Outlet recommends doing for every Turin grinder

Interesting....first I'm hearing about adjusting the grind while the motor is running but I'll give it a try

Yes, that is a typical spring lever pressure profile. Variations on this theme have been my go-to on the Decent since day one. {image} Example: preinfuse at 6ml/s, raise pressure to 9 bar, then smooth decline to 6 bar over 35s

Just my experience, but I had the dimmer mod and removed it as I found it unpredictable when actually pulling a shot. I ended up with three settings with the dimmer - max on, min on, and somewhere in between - but even then I could not get a repeatable pre-infusion pressure (again, when actually pulling shots - I did
