Abstract
A coffee machine comprises a fresh water reservoir. A heating block, having a first flow heater pipe, is in fluid communication with the reservoir via a first connection line and a second connection line. The first connection line has a check valve disposed therein, the second connection line has a pump disposed therein. A coffee-making head is in fluid communication with the heating block via a pipe. The pipe ascends from the heating block to the coffee-making head. A steam nozzle is in fluid communication with the heating block via a steam line. A device fluidly connects the reservoir with the steam outlet when the pump is operating.
