If the illuminated pushbutton “Water alarm” on your MTU Engine is lit, this indicates that the maximum water level has been reached. Press the illuminated pushbutton “Water alarm” to acknowledge. In addition to the automatic water drain function, water can also be drained manually by pressing the illuminated pushbutton “Water drain” to open the drain valve.
