Struggling to dial in
Hi all
Got my ES1 today and have spent the afternoon playing around with it, and no matter what I do can’t get my shots not to gush - whatever grind size I use I’m getting 36-40g out in exactly 17 seconds (with a 10 second pre-infuse). I’ve tried a bunch of settings from 20 down to 3 on the grinder with the same result - and I’ve calibrated it to reset 0.
Im using a Niche Zero grinder and the exact same beans I was using with my Sage Bambino Plus yesterday (where i was grinding at about 10 and 36-38g out in 27-ish seconds.
Conscious the problem i’m having indicates a puck prep/channelling issue but my routine hasn’t changed either - 18g in, WDT and tamp (using a new Normcore tamper with the 30lb spring in - I’ve tested it on a scale and it’s working fine). Really the only things that have changed are the portafilter size and the machine - I’m genuinely at a loss.
Any tips appreciated.
