  • Publication number: 20120291633
    Abstract: A beverage machine (1) or a preparation machine, in particular a coffee machine has a main flow path (5) that leads from a line connection or a tank (2) through a boiler (3) to a dispensing location (4). The boiler (3) is connected to the tank (2), to a drip pan (8), to a drain or a dispensing location via a line (7) that encompasses a valve (6). In the case of a boiler (3) that is in the stand-by state, the valve (6) is at least partially open, whereby an unpressurized, open boiler system is at hand. A control device (9), actuates the valve (6) and closes the valve (6) provided that a demand is at hand. A combination of the advantages of a closed and of an open boiler system is possible through this.
