What to do if the illuminated pushbutton “water alarm” is lit on my MTU 10 V 2000 M84?

If the maximum water level is reached, the water level electrode opens the water drain valve, discharging water. If the valve's opening time exceeds 4 minutes, the pump shuts off and an alarm activates. To address this, first, press the illuminated “Water alarm” button to acknowledge the alarm. You can also manually drain water by pressing the “Water drain” button to open the drain valve.
