What does it mean when the "Level" symbol flashes on my ProMinent Sigma/ 2 Control S2Cb Water Pump?

When the "Level" symbol flashes on the LCD screen along with the error message „Level warning“ W1-3, it indicates that the fluid level in the storage tank has reached "Liquid level low 1st stage". To resolve this, top up the storage tank.
