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 hydrau

lic 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 (assis
-
tance service).
3. Check the suction pipe, find
and eliminate the cause of air
getting in.
4. Contact the assistance centre.

1. Suction depth too
high.
2. Suction pipe
clogged or diame
-
ter insufficient.
3. Impeller or hydrau
-
lic part clogged.
1. As the suction depth increases
the hydraulic performance of
the product decreases (
De-
scription of the Electropump
).
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

Expansion vessel
empty (insufficient
air pressure) or has
broken diaphragm.
Check the air pressure through
the valve in the technical compart
-
ment. If water comes out when
checking, the vessel is broken:
assistance service. Otherwise
restore the air pressure according
to the equation par. 1.2.
