If the problem persists despite the recommended corrective actions, contact the Customer Assistance Service.
PROBLEM POSSIBLE CAUSE REMEDY
THE PUMP IS NOT RUNNING
1) No water. Red LED light on (FAILURE)*. Identify the cause, and then restart by
pressing the RESTART button.
2) Pump stalled. Identify the cause and unblock the pump.
3) No current. Check that power is present and that the plug has been inserted
properly. The Green LED light (power On) is off*.
4) FLUSSCONTROLL* is faulty. Contact the Customer Assistance Service.
THE PUMP DOES NOT STOP
1) Reset button blocked. Inspect the pump and clean it if necessary.
2) The pump sucks air. See point 4.
3) FLUSSCONTROLL* faulty. Contact the Customer Assistance Service.
THE ELECTROPUMP DOES NOT PUMP WATER,
THE MOTOR DOES NOT RUN
1) No power. Check that power is present and that the plug has been inserted
properly. The Green LED light (power On) is off*.
2) Motor protection tripped. Identify the cause, and then restart by pressing the RESTART* button.
Wait until the system has cooled down if the thermoregulator has
intervened.
3) Defective condenser. Contact the Customer Assistance Service.
4) Shaft blocked. Identify what caused the block:
a) Make sure that the power supply cable has been unplugged
b) Remove the fan cover
c) Try to unblock the shaft by turning the cooling fan.
Contact customer services if the problem persits
THE MOTOR RUNS BUT THE ELECTROPUMP
DOES NOT PUMP LIQUID
1) The pump is sucking air. Check to ensure that joints are leak proof.
Check that liquid levels have not decreased beneath the foot valve.
Check to ensure that the foot valve is unblocked and leak proof.
THE ELECTROPUMP STOPS AFTER RUNNING FOR
A SHORT PERIOD OF TIME BECAUSE ONE
OF THE THERMAL MOTOR CIRCUIT BREAKER TRIPS
1) The power supply does not comply with
the data on the nameplate.
Check the voltage on the power supply cable leads.
2) A solid object is blocking the impellers. Contact customer services.
MAINTENANCE AND TROUBLESHOOTING
CHAPTER 7
• In ordinary conditions, NOCCHI series
electropumps do not require any
maintenance
• To prevent possible problems, it
is advisable to periodically check
the pressure supplied and current
absorption
• A reduction of the pressure may
indicate that the electropump is worn
• Sand and other corrosive materials
present in the delivery fluid cause
a rapid wear and a reduction of
performance
• In this case, it is advisable to use
a filter
• An increase in current absorption
indicates the presence of abnormal
mechanical friction in the pump and/
or the motor
• If the electropump is not going to be
used for a long period of time (i.e.
one year), it is advisable to empty it
completely (by opening the drain cap,
see Fig. 1 n. 10), rinse it with clean
water and store it in a dry location,
where it can be protected from frost
GB
Make sure the machine is disconnected from electric power supply, before performing maintenance
operation.
