Bright Solutions for Dealing with F28 Error on Glow Worm Boiler

When your Glow Worm boiler displays the F28 fault code, it usually indicates a problem with the gas supply. This could be due to a variety of reasons, such as a faulty gas valve, a blocked gas supply, or issues with the pressure sensor. One of the first things you can do to address this error is to check if your gas supply is turned on and that there are no blockages in the gas line. If everything seems to be in order, you may need to call a professional technician to inspect and repair any faulty components.

Another common cause of the F28 fault code on Glow Worm boilers is a problem with the ignition system. If the ignition is not working properly, the boiler won’t be able to start up and heat your home. In this case, you may need to reset the boiler by turning it off and then on again. If the issue persists, you may need to clean or replace the ignition components. Remember, always consult the manufacturer’s manual or contact a qualified technician for assistance with any repairs or replacements.

In some cases, the F28 fault code on Glow Worm boilers may be triggered by a more serious issue, such as a faulty PCB (printed circuit board). If you suspect that the PCB is the culprit behind the error, it’s best to seek professional help to diagnose and fix the problem. Don’t attempt to repair or replace the PCB yourself, as doing so may void your warranty or cause further damage to your boiler. By addressing the F28 fault code promptly and with the help of a trained professional, you can ensure that your Glow Worm boiler continues to provide you with reliable and efficient heating for years to come.
