TROUBLESHOOTING
Warning:
Before any maintenance or repair activities, make sure that the power supply is cut off and
cannot be turned on by accident.
Issue:
Possible cause:
Solution:
The pump fails to launch
Tripped installation fuse
Check the cause, replace the fuse
Overcurrent circuit breaker switched off
Start the breaker
Pump damaged
Replace the pump
Voltage too low
Check if the main voltage
is compliant with the supplier's
specification
Pump rotor blocked
Unlock the rotor
Loud system operation
Air in the installation
Vent the installation
Flow too high
Decrease the inflow pressure at
the pump inlet
Loud pump operation
Air in the pump
Vent it
Inflow pressure too low - cavitation
Increase the inflow pressure at the inlet to
the
pump
Heat insufficiency in the installation
Pump parameters too low
If possible, increase the pump operation
mode into a more efficient one,
otherwise
install stronger pump
