Cause
The hydraulic system of the pump is pow-
ered, but the pump has no mains voltage
Air in the pump
The motor runs with difficulty. The number
Overload of revolutions is lower compared to normal
operation
Supply voltage too low/high
Excessive temperature inside the pump
Short circuit Motor current too high
Rotor blocked

Circuit board and/or motor failure
Electrical power failure

Possible solution
- Check the mains voltage
- Check that there are no leaks in the
system
- Check the mains voltage
- Check the system flow rate/pressure
- Check the characteristics of the water
in the system; remove debris from the
system
- Check the mains voltage
- Check the water temperature level in re-
lation to that of the ambient temperature
- Check the mains voltage
- Check the environmental operating condi-
tions
- Check the mains voltage
- Restart manually
- REPLACE THE PUMP
- REPLACE THE PUMP
- Check the connection to the power supply
- Check to see if the pump can work
- REPLACE THE PUMP
