FAULT/MALFUNCTION
1) The electric pump does not get started
or stops unexpectedly
2) The electric pump gets started but
does not deliver any flow, dispenses
irregularly, or the flow rate is much
lower than values specified on the
rating plate
3) The electric pump overheats,
thermal protection trips, operation is
anomalous
11 TROUBLESHOOTING
• For single-phase models with a control panel: check that the switch is set on "I". If the manual reset thermal
magnetic switch is present, press the reset button. Check that the capacitor is intact.
• For single-phase models without a control panel: check that the installed capacitor is correct, connected correctly
and undamaged.
• For models with a float, check the travel of the float and lift it manually to check that it works.
• Check whether the circuit breakers and residual current devices have been enabled; check that fuses (if any) are
intact.
• Check the electrical connection to the mains.
• Make sure the mains supply voltage is on.
• FOR PROFESSIONAL MAINTENANCE TECHNICIANS ONLY: make sure the pump can rotate freely and power
consumption does not exceed the value on the rating plate..
• For submerged units: check that the filter is not clogged and that the pump is submerged at least to the specified
minimum limit
• For surface units: check that the pump is primed and does not cavitate
• Make sure there is no air in the hydraulic conduit; vent pipes
• For three-phase models: check the rotation direction
• Check the electrical connections of the power supply and the direction of rotation
• Check that there is flow rate and that it is within the values indicated on the data plateCheck that the pump is free
of encrustations or deposits, especially on the surfaces of the motor cartridgeCheck the level and temperature of
the liquid in the tank (submerged installations)Check that engine start-up is quick
