i doubt it needs to be said, but i omitted to write it into the instruction manual and its 1:30am and I’m worried that someone out there is struggling with the machine as a result of open port flushing – please don’t open port flush, other than when you turn the machine on and you pull about 450mL through the group with the double basket and PF locked in the group, as instructed in the manual
by open port flush i mean pull the lever down when no coffee is in the portafilter basket
open port flushing is NEVER required on LONDINIUM I (other than for the initial warm up)
open port flushing will raise the temperature of the group above its designed optimum temperature range
so please, no open port flushing – we’ve spent a lot of time on the design so none of this nonsense and fluffing around is required
londinium i – no rituals, just exceptional espresso
