MELITTA BOSCH SIEMENS NIVONA MIELE KRUPS DRAINAGE VALVE 6769601 00622540 046 A drainage valve in coffee machines is a component responsible for controlling the release of excess water or liquid from the brewing system. It helps to ensure that the machine can maintain the correct pressure and function efficiently by draining any leftover water after the brewing cycle. The valve typically opens to allow the water to flow out into a drip tray or waste container, preventing water from accumulating inside the machine, which could otherwise lead to issues like overflow or inconsistent brewing performance.
