What to do if the illuminated pushbutton “water alarm” is lit on my MTU Engine?

When the maximum water level is reached, the water level electrode opens the water drain valve to discharge water. If the valve's opening time surpasses a pre-set limit of 4 minutes, the pump shuts down, triggering an alarm. To address this, first, press the illuminated “Water alarm” button to acknowledge the alarm. Furthermore, besides the automatic water drain, you can manually drain the water by pressing the illuminated “Water drain” button, which opens the drain valve.
