Regarding adjusting grind, yes tightening and loosening the red knob is pretty effortless. I noticed when I first started using the grinder the adjustments can be small to make a noticeable grind difference. It's neither here nor there, but just something I've noticed. I don't have any retention issues to speak of. I do use the forks to slap

yes the 45 second is just a dumb timer no sensor. so if your grind is not finish by 45 second it will stop no mater what do rdt it will help with retention

Hi does anyone know a good medium-dark roast decaf to try for straight espresso I recently tried Propeller Coffees swiss decaf and it was just too sour for me

I've had my Rocket Cellini for over 7 years now. Always fed filtered water, with Oscar pour he's for the last 2-3 years. Last few weeks it hasn't been generating sufficient flow rate. I've since descaled the group head and replaced the ulka pump. Still no luck. Is this HX route scale issue? Looking for advice on next steps

The early version did not have PID control. So I added a heating ring and PID controller to warm the water chamber. It takes 10-15 min to get cold water to ~92C in the chamber, works very well. {image}

The silicon disk was used in its early version. I bought one 4-5 years ago when I was working in China. They changed to stone disk later and now back to silicon disk. Don't know why. You could remove the disk, which I did. Then you may need to add extra ~20ml water to compensate the volume of

100% correct - easiest thing ever. It's infinitely adjustable and everything is super smooth

Update: I got my OPV from Chris Coffee (although they apparently call it an expansion valve), and had a chance today to put it in. It seemed to fix the problem, although the pump seemed pretty wonky. It is about three years old, was running hard because of the problem, and I had a spare

My retention is running at around 0.4 right now. Odd that it's about the same with clean or "used" funnel. I've only ran maybe 170g through it so I will wait a bit more to see how things settle

Thank you!!
