If your Lowara Water Pump doesn't start, it could be due to a tripped thermal protector. In this case, wait for the pump to cool down; the thermal protector should reset automatically. Alternatively, the protective device against dry running may have tripped. Check the liquid level in the tank or the mains pressure.
Why does the thermal protection trip after Lowara e-NSCS starts?
The thermal protection in your Lowara Water Pump might be tripping because the pump is overloaded, possibly due to pumping liquid that's too dense or viscous. In this case, check the actual power requirements based on the characteristics of the pumped liquid and then contact the Sales and Service Department. Another reason may be that there are foreign objects (solids or fibrous substances) inside the pump which have jammed the impeller. In this case, contact the Sales and Service Department.
