I have had my machine for sometime now, over 6 months ago and can only sing it's praises to anyone who will listen to me :ok_hand: I have not had any negative comments from friends when I offer a coffee. They are always surprised how great the machine is and then the coffee. My barista skills are improving. My only question is their any need to do a "reverse flush" in addition to the already suggested maintenance? I want keep it in great working order.
