Troubleshooting the F28 Boiler Fault Vaillant: Easy Fixes

If you’re experiencing the dreaded F28 boiler fault on your Vaillant system, the first thing to check is the gas supply. Make sure that the gas valve is fully open and that there are no blockages in the supply line. If everything looks good, try resetting the boiler by turning it off and then back on again. Sometimes a simple reboot is all it takes to clear the fault and get your system working again.

Another common cause of the F28 fault is a problem with the ignition. Check to see if the pilot light is lit and that there are no obstructions preventing it from igniting properly. If the pilot light is out, try relighting it following the manufacturer’s instructions. You may also want to check the ignition leads and electrodes for any damage or wear and tear that could be causing the fault.

If the F28 fault persists after checking the gas supply and ignition, it may be worth checking the pressure in your system. Low pressure can cause the boiler to shut down and display this error code. Check the pressure gauge on your boiler and if it is below the recommended level, you may need to top up the system with water. Be sure to follow the manufacturer’s instructions for refilling the system to avoid causing further issues.
