To reset the boiler, press and hold the reset button located on the control panel for about 3 seconds until the reset light turns off.
If your boiler is leaking, check the pressure relief valve and all visible pipework for leaks. If the source of the leak can't be identified, contact a qualified engineer.
To increase the water pressure, locate the filling loop (usually beneath the boiler) and open the valves to allow water into the system until the pressure gauge shows a reading between 1.0 and 1.5 bar.
Check if the boiler is displaying any error codes. Ensure the thermostat is set correctly and that the boiler has power. If the issue persists, a component such as the diverter valve might be faulty and require inspection by a technician.
It is recommended to have your boiler serviced annually by a qualified heating engineer to ensure it operates efficiently and safely.
Error code A1 indicates a problem with the fan. It might need cleaning or replacement. Contact a certified technician to diagnose and fix the issue.
No, the boiler requires electrical power to operate. It will not function during a power outage. Consider alternative heating solutions for such situations.
Turn off the heating system and use a radiator key to open the bleed valve slowly until air stops hissing and water starts to trickle out, then close the valve.
Regularly check the boiler pressure, bleed radiators, and ensure vents are unobstructed. Always refer to the user manual and consult a professional for major maintenance.
Some noise is normal, such as the sound of the fan or burner. However, loud or unusual noises like banging or whistling could indicate an issue and should be investigated by a professional.
