ABSTRACT:
The automatic espresso coffee machine brews coffee from coffee pods placed in an extraction head or in a plurality of extraction heads and is characterized in that it comprises an electronic control system, including a microprocessor and memory means, which operate all the operations of the machine. In particular, the machine carries out a continuous control of the water temperature in a boiler in order to keep that temperature in a narrow range of a selected temperature. It also controls the volume of the hot water delivered to each extraction head to be within a narrow range of predetermined volume. The machine diagnoses itself for possible failures and depleted supplies by showing on a display in code the kind of failure or of needed supply, i.e. coffee.
