9.1 Boiler Filling and Emptying

Filling
The filling of the boiler depends on the filling level. Via the water coupling, water
(green path) is sucked in by the water pump and pumped into the boiler. A minimum
leakage via the vent valve of the pump is unavoidable due to the system and is led
into the drip tray via the drain hose.
Emptying
At the end of the cleaning, the hot water
outlet nozzle on the RF box into the cleaning container using the internal boiler pres-
sure. To reduce the water temperature, cold water is added via the milk pump (this
path is not shown in the figure below).
