Based roughly on the manual, this is my routine: Turn on at swtich, open the steam wand. Wait until pump has stopped and turn off the steam wand. Wait for 5ish minutes, or until the gauge reads 1-ish bar. Turn the steam wand on for 5 seconds. Turn off. Take the group handle out, flush water for two seconds. Put the group handle back in. Wait for the machine to fully warm up, around 30 minutes.
Pulling shots, my routine is to change the grind according to the environment temperature. Grind out any residual coffee. Put enough coffee into hopper. Grind out some more coffee (as my grinder retains some grinds in the chute). Grind for a shot, backflush the machine, collapse the coffee twice, tamp, polish, insert the group handle into the machine, and brew. Wallah! COFFEE!
