I think what is being said is for all the machine to warm up takes about 90 mins, the water would be warm in minutes but the portafilter and internall pipes and all that would still be room temp so would cool the the water down as it came down to the coffee, giving a lower than ideal brewing temp, even with my pityful gaggia :icon_cry2: (compared to Mikaels new machine) I give it at least 20 mins to warm up, and if I am home at weekends I will just leave it on as will get used every hour or two anyway.
It is a lovely machine Mikael and the shots look great
