TROUBLESHOOTING
Before starting to look for faults it is necessary to disconnect the power supply to the pump (take the plug out of the socket). If the
power cable or any electrical part of the pump is damaged, the repair or replacement must be carried out by the manufacturer or
by their technical assistance service, or by a person with equivalent qualifications, so as to prevent any risk.
FAULTS
The pump does not turn on or
does not stay on.
La pompa non si arresta.
The flow rate is insufficient.
The pump does not deliver water.
The pump starts without utility
request
The pump does not start and the
status signal is BL
The pump does not start and the
status signal is PB

PROBABLE CAUSES
Pump is not powered.
No water.
Utility at a level higher than the system restarting
pressure level.
Leak in the system.
Impeller or hydraulic part clogged.
Air getting into the suction pipe.
Suction clogged.
Suction pipe diameter insufficient.
The suction grid or the pipes are blocked.
The impeller is worn or blocked.
The head required is higher than the pump's
characteristics.
Leak in the system.
Lack of water or pump not primed
Obstruction in suction
Setpoint not reachable with the set RM value
The non-return valve is blocked
Low supply voltage
Excessive voltage drop on the line
ENGLISH
Check power supply.
Restore the water level.
Increase the system restarting pressure level by
increasing SP or decreasing RP.
Check the system, find and eliminate the leak.
Dismantle the system and remove the obstructions
(assistance service).
Check the suction pipe, find and eliminate the cause
of air getting in.
Remove the obstructions
Use a pipe with diameter at least 1"
Remove the obstructions.
Replace the impeller or remove the blockage.
Check the system, find and eliminate the leak.
Prime the pump and check whether there is air in the
pipe.
Check whether the suction or any filters are blocked.
Set a RM value that allows the setpoint to be
reached.
Remove obstruction on the non-return valve
Check the presence of the correct supply voltage.
Check the section of the power supply cables.
