BoilerFaultCodesThe 6 most common faults
Your boiler has become too hot and has automatically shut down to prevent damage or safety issues.
Allow the boiler to cool down for at least 20 minutesCheck that your radiator valves are open and not blockedPress the 'Reset' button on the front control panel
Your boiler has stopped working because the water pressure is too low and needs to be topped up.
Locate the filling loop (usually a silver braided hose with two valves underneath the boiler)Slowly open both valves until you hear water flowing and the pressure gauge needle movesClose both valves tightly when the needle reaches 1.5 bar, then restart the boiler
Your boiler is not receiving a steady gas supply or is struggling to light and maintain a flame.
Check if your gas meter has credit (if using a pre-payment meter).Ensure the gas emergency control valve is in the open position.Attempt to reset the boiler by pressing the reset button for five seconds.If it is freezing outside, check that the white plastic condensate pipe has not frozen.
Your boiler has detected that water is not circulating correctly through the system before the burner ignites.
Check that the main cooling valves and radiator valves are fully openCheck the central heating pressure gauge is between 1 and 1.5 barGently bleed air from your radiators using a radiator key
Your boiler has become too hot and has shut itself down as a safety precaution to prevent damage.
Switch off the boiler and allow it to cool down completely.Use a radiator key to bleed any trapped air from all radiators in your home.Check that your system pressure is correct and press the reset button on the boiler control panel.
Your boiler has stopped working because the water pressure in the system has dropped too low to operate safely.
Locate the filling loop (usually a silver braided hose with two valves under the boiler)Slowly open both valves to let water into the systemClose the valves tightly when the pressure gauge reaches between 1 and 1.5 bar
on the Baxi Suprima 60
Based on parts cited in our fault code database. Your engineer will confirm what's actually needed after diagnosis.
Call a Gas Safe engineer if…
- You can smell gas or see signs of a leak
- The Baxi shows an Emergency or High severity code
- The boiler keeps locking out after repeated resets
- You've tried the DIY checks and the fault hasn't cleared
- There's visible water leaking from the boiler
- The flame is yellow or orange instead of blue
