To reset your Baxi 800 Heat boiler, press the reset button on the control panel and hold it for about 5 seconds until the boiler restarts.
First, check if the gas supply is on and the thermostat is set at the desired temperature. If it still doesn't fire up, check for error codes and consult the manual or a professional engineer.
It is recommended to service your Baxi 800 Heat boiler annually to ensure it operates efficiently and safely.
Error code E133 indicates a flame failure or that the gas supply has been interrupted. Check the gas supply and reset the boiler. If the problem persists, contact a professional engineer.
To increase the pressure, locate the filling loop, and slowly open the valves while keeping an eye on the pressure gauge. Close the valves once the desired pressure is reached.
Banging noises could be due to air in the system, low water pressure, or a buildup of limescale. Bleed the radiators or consult a professional engineer if the issue persists.
Turn off the heating system, then use a radiator key to open the bleed valve slightly. Once the hissing stops and water starts to flow, close the valve.
Regularly check the pressure, bleed the radiators, and ensure the vents and flues are clear. An annual service by a professional is also recommended.
Ensure regular servicing, bleed radiators to prevent blockages, insulate pipes, and use a thermostat to control heating effectively.
Turn off the water supply and heating system, then contact a qualified engineer to inspect and repair the leak.
