I have tryed for 3 month now,to make a good espresso, and haven't done it yet. The water in machine is yellow when it comes out, taste and smell very bad. Even if I turn it on 3-4 hours the water in the group heat is "cold" and do not reach 94º. I tryed almost everything cleaning, backfluss and adjust the temperature up and down(presure for steaming) less coffe, more coffe, harder/ softer tamping but nothing works, still cold bitter taste, not like coffe should taste..:o(
If anyone have an idea I'll be happy..:o)
didn't ship on time 2 weeks late, and without the promised tamper. And machine full of water.
Three Month Followup
6 month later...and the Isomac cant make coffe. The water is still yellow and smelly. Almost only use it for steaming milk.
