Remedies
Check whether there is voltage
in the socket and insert the
plug again.
See paragraph 9.4 (motor shaft
maintenance).
Increase the system restarting
pressure level by increasing
SP or decreasing RP.
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 eliminate the cause of
air getting in.

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
counterslope..) and remove
it.
3. Dismantle the system and
