Baxi 615 System Installation and Service Manual

To reset your Baxi 615 System boiler, locate the reset button on the control panel. Press and hold it for a few seconds until the boiler restarts. Make sure to consult the user manual for specific reset instructions if needed.
First, check if the thermostat is set correctly and the boiler is receiving power. Ensure that the water pressure is within the recommended range (typically 1-2 bar). If the issue persists, examine the pilot light or error codes on the display and refer to the manual for troubleshooting steps.
It is recommended to service your Baxi 615 System boiler annually by a qualified engineer. Regular servicing helps ensure efficiency, safety, and early detection of potential issues.
Error code E133 indicates a gas supply issue or a problem with the ignition process. Check the gas supply to your property, reset the boiler, and if the error persists, contact a qualified technician for further diagnosis.
To increase the water pressure, locate the filling loop beneath the boiler. Open the valves slowly until the pressure gauge reaches the recommended level (1-2 bar). Close the valves once the correct pressure is achieved.
Loud banging noises, often called "kettling," can be due to limescale build-up or air trapped in the system. Bleed the radiators and consult a professional to descale the heat exchanger.
Turn off the heating system and allow the radiators to cool. Use a radiator key to open the bleed valve, releasing air until water starts to flow. Close the valve and check the boiler pressure, topping up if necessary.
Frequent pressure loss can indicate a leak in the system or a faulty pressure relief valve. Inspect visible pipes and radiators for leaks and consult a heating engineer to diagnose and repair the issue.
Yes, you can install a smart thermostat with your Baxi 615 System boiler. Ensure compatibility by consulting the thermostat's manual and consider professional installation for optimal integration.
You can perform basic maintenance tasks such as checking and adjusting the water pressure, bleeding radiators, and cleaning accessible parts of the boiler. Always refer to the user manual and seek professional help for complex tasks.
