What does it mean if the signal lamp “Pump fault” is lit on my MTU 16 V 4000 M63R Engine, and what should I do?

If the “Pump fault” signal lamp is lit on your MTU Engine, it means the drive motor's overload protection has been triggered, possibly due to a blockage or dry-running. To resolve this, reset the motor protection relay.
