Summary: The warning lights for NO WATER and NO BEANS are side-by-side as are the lights for SCALING and PUCK CONTAINER FULL.
Pros: Adjusted the grind as directed. Makes great espresso and after adjusting the water volume, the Americana quite good also. The Saeco distributor helped me with my one 'con' in a matter of minutes.
Cons: The lights for "scaling" and for "Puck Container Full" were confusing to me.
