  Antonio NavarroAug 8, 2025
  If the illuminated pushbutton “Water alarm” is lit on your MTU Engine, it indicates that the maximum water level was reached, causing the water level electrode to open the water drain valve. If the valve's opening time exceeds 4 minutes, the pump shuts off and triggers the alarm. To resolve this, first, press the illuminated pushbutton “Water alarm” to acknowledge the alarm. You can also manually drain the water by pressing the illuminated pushbutton “Water drain” to open the drain valve.
