PCB is faulty Spark electrode is faulty. Ignition transformer is faulty. PCB is faulty. Check gas pressure. Check mains gas safety valve. Reconnect gas valve Replace it. Replace it. Replace it. Replace ignition transformer Replace PCB The boiler has shut down, and red light 5 is flashing. Turn selector 9 to RESET position to resume boiler operation. Burner ignites for a few seconds and goes off. Flame detection electrode wire is disconnected or faulty. Verify correct neutral and phase connections. Connect flame detection electrode wire or replace it Burner ignites for a few seconds and goes off. Detection electrode is faulty. PCB does not detect flame Replace electrode Replace PCB P ACC ignition value setpoint is too low. Adjust P ACC ignition value set point Min. heat input is not set correctly. Check burner adjustment Condensate is not discharged. Condensate drain is clogged. The trap is full. Check the condensate drain Check the condensate trap and boiler drain Flue pressure switch is faulty Check flue pressure switch and replace if necessary Flue pressure switch not operating Silicon pipes are disconnected or faulty Reconnect or replace silicone pipes The boiler has shut down and red light 4 is flashing. Turn selector 9 to RESET position to resume boiler operation. Insufficient air intake or flue gas discharge Fan is faulty PCB is faulty Check air/flue gas pipes: unclog or replace as required Replace it. Replace it. Boiler safety thermostat has shut boiler down Insufficient air intake or flue gas discharge Check air/flue gas pipes: unclog or replace as required The boiler has shut down and red light 3 is flashing. Turn selector 9 to RESET position to resume boiler operation. Boiler safety thermostat has shut boiler down CH water does not flow: pipes might be clogged, thermostatic valves might be shut, system stopcocks might be closed. Pump is stuck or faulty. Check CH system. Check the pump. Possible water leaks. Check system for leaks. The boiler has shut down and red light 6 is flashing. Reset boiler by restoring correct water pressure. Insufficient water pressure Pressure switch is disconnected Water pressure switch is faulty. Reconnect it. Replace it. 44
