1. Suction depth too high.
2. Suction pipe clogged or
diameter insufficient.
3. Impeller or hydraulic
part clogged.
1. As the suction depth increases the
hydraulic performance of the product
decreases. Check whether the suction
depth can be reduced. Use a suction
pipe with a larger diameter (but never
smaller than 1”).
2. Check the suction pipe, find the cause
of choking (obstruction, dry bend,
counterslope, …) and remove it.
3. Dismantle the system and remove the
obstructions (assistance service).
The pump
starts without
utility request.

1. Leak in the system.
2. Faulty non-return
valve.
1. Check the system, find and eliminate
the leak.
2. Service the non-return valve as
described in par. 9.3.

Expansion vessel empty
(insufficient air pressure)
or has broken diaphragm.
Check the air pressure in the expansion
vessel. If water comes out when checking,
the vessel is broken: assistance service.
Otherwise restore the air pressure accord -
ing to the equation par. 1.2.
When the
utility is
turned on the

Red: off
White: on
Blue: off
Air pressure in the expan -
sion vessel higher than the
system starting pressure.
TCalibrate the expansion vessel pressure or
configure the parameters SP and/or RP so
as to satisfy the equation par.1.2.
10 - 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).

Utility at a level higher
than the system restarting
pressure level (par. 3.2).
Increase the system restarting pressure
level by increasing SP or decreasing RP.

1. Leak in the system.
2. Impeller or hydraulic
part clogged.
3. Air getting into the
suction pipe.
4. Faulty flow sensor
1. Check the system, find and eliminate
the leak.
2. Dismantle the system and remove the
obstructions (assistance service).
3. Check the suction pipe, find and elimi -
nate the cause of air getting in.
4. Contact the assistance centre.
