TROUBLESHOOTING
FAULTS POSSIBLE CAUSES REMEDIES
The pump does not start
No supply voltage
Check the electric connections
and the fuses
Incorrect supply voltage
Check the data on the plate and
apply the correct voltage
Faulty capacitor
(single-phase motors)
Change the capacitor
Rotor blocked by deposits on
the bushes
Select the maximum speed
and/or free the rotor with a
screwdriver
The system is noisy
Flow rate too high Select a lower speed
Air in the system Bleed the system
The pump is noisy
Air in the pump Bleed the pump
Intake pressure too low Increase the intake pressure
The pump starts and then
stops after a short time
Dirt or scale between the
rotor and the stator lining or
between the impeller and the
pump body
Check that the shaft is turning
freely. Remove any dirt and/
or scale
