14. 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).

ENGLISH
PROBABLE CAUSES
No electric power.
Shaft blocked.
Utility at a level higher than the
system restarting pressure
level (par. 3.2).
1. Leak in the system.
2. Impeller or hydraulic part
clogged.
3. Air getting into the suction
pipe.
4. Faulty flow sensor.
1. Suction depth too high.
2. Suction pipe clogged or
diameter insufficient.
3. Impeller or hydraulic part
clogged.
1. Leak in the system.
2. Faulty non-return valve.
Expansion vessel empty
(insufficient air pressure) or
has broken diaphragm.
Air pressure in the expansion
vessel higher than the system
starting pressure.
1. No water.
2. Pump not primed.
3. Setpoint not reachable with
the set RM value
1. Faulty pressure sensor.
1. Excessive absorption.
2. Pump blocked.
1. Supply voltage too low.
2. Excessive drop in voltage
on the line.
One or more devices have
sensitive parameters not
aligned.

REMEDIES
Check whether there is voltage in the socket and insert the plug again.
See paragraph 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.
4. Contact the assistance centre.
1. As the suction depth increases the hydraulic performance of the
product decreases (see par. Description of the Electropump). Check
whether the suction depth can be reduced. Use a suction pipe with a
larger diameter (but never smaller than 1"1/4 for the single pump,
larger sections for groups).
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).
1. Check the system, find and eliminate the leak.
2. Service the non-return valve as described in paragraph 12.3.
Check the air pressure through the valve in the technical compartment. If
water comes out when checking, the vessel is broken: assistance service.
Otherwise restore the air pressure according to the equation (par. 1.4).
Calibrate the expansion vessel pressure or configure the parameters SP
and/or RP so as to satisfy the equation (par. 1.4).
1-2 Prime the pump and check whether there is air in the pipe. Check
whether the suction or any filters are blocked.
3. Set a RM value that allows the setpoint to be reached.
1. Contact the assistance centre.
1. Fluid too dense. Do not use the pump for fluids other than water.
2. Contact the assistance centre.
1. Check the presence of the correct supply voltage.
2. Check the section of the power supply cables.
Press the ^ key on the device which we are sure has the most recent and
correct configuration of the parameters.
