Troubleshooting for the pump with LED (if present)

LED colour Pump status
"Transient safety shutdown"; Anomaly
in progress
Red-Green
flashing
After eliminating the anomaly, the pump
restarts automatically
Flashing red "Permanent safety shutdown"
LED off Stationary
Solution
- Check for blockage in
chimney
- Check air diaphragm (for
BF models)
- Check gas calibration
- Bleed the air from the gas
circuit
- Check electrode
- Check outlets
- Check air diaphragm (for
BF models)
- Check gas calibration
- Check for blockage in
chimney
- Check air diaphragm (for
BF models)
- Check gas calibration
- Check gas flow rate
- Check the board is working
- Replace board

Fault
Network voltage too high or too low;
(160V > Vn > 280V)
Motor overload; rotor friction or blockage
due to the presence of debris
Excessive speed; the pump rotor is
actuated by an external factor and is
rotating at a speed exceeding the maximum
permitted speed
Overcurrent; stator winding is in short
circuit due to water
The temperature inside the motor is too
high
The pump is obstructed by an external flow
(> 1200l/h) in the opposite direction
Pump blocked due to debris in the system
Fault in the electronic board and/or the
motor
No electrical power
LED faulty
Electronic board faulty
Type No. Fault

Maintenance request

When it is time to perform maintenance on the boiler, the
symbol shows on the display.
Contact the technical assistance service to organise the
necessary work.
Possible solution
- Check network voltage
- Check the characteristics of the system
water; clean the system of any debris
- Check that there is no external flow in the
system (no other pump in operation)
- Check for leaks in the system
- Check the water temperature in relation
to ambient temperature
- Eliminate or reduce the external flow (<
1200l/h)
- Remove and reconnect the electrical
power supply (OFF - ON)
- If the "red LED" continues to flash:
- REPLACE THE PUMP
- Check the electrical power connection
- Check if the pump can operate
- REPLACE THE PUMP
Solution
- Check electrode
- Check board
- Check electric power supply
- Check gas calibration
- Check for blockage in
chimney
- Check the smoke outlet
and electrode position (not
touching the burner)
- Contact the Technical
Assistance Centre
- Contact the Technical
Assistance Centre
- Check circuit pressure
- Check expansion vessel
- Check the diverter valve
- Check that plate heat
exchanger is clean
- Check domestic hot water
circuit valve
