Maintenance request
When it is time to perform maintenance on the boiler, the
c
symbol shows on the display.
Contact the technical assistance service to organise the
necessary work.

Troubleshooting for the pump with LED (if present)
LED colour
Pump status
Fault
Possible solution
Red-Green
flashing
"Transient safety shutdown"; Anomaly
in progress
After eliminating the anomaly, the pump
restarts automatically
Network voltage too high or too low;
(160V > Vn > 280V)
- Check network voltage
Motor overload; rotor friction or blockage
due to the presence of debris
- Check the characteristics of the system
water; clean the system of any debris
Excessive speed; the pump rotor is
actuated by an external factor and is
rotating at a speed exceeding the maximum
permitted speed
- Check that there is no external flow in the
system (no other pump in operation)
Overcurrent; stator winding is in short
circuit due to water
- Check for leaks in the system
The temperature inside the motor is too
high
- Check the water temperature in relation
to ambient temperature
The pump is obstructed by an external flow
(> 1200l/h) in the opposite direction
- Eliminate or reduce the external flow (<
1200l/h)
Flashing red
"Permanent safety shutdown"
Pump blocked due to debris in the system
- Remove and reconnect the electrical
power supply (OFF - ON)
Fault in the electronic board and/or the
motor
- If the "red LED" continues to flash:
- REPLACE THE PUMP
LED off
Stationary
No electrical power
- Check the electrical power connection
LED faulty
- Check if the pump can operate
Electronic board faulty
- REPLACE THE PUMP
