A Bright Solution: Fixing Your F13 Glow Worm Boiler Fault

When faced with an F13 fault code on your Glow Worm boiler, the first thing to do is check the water pressure. Low water pressure is a common cause of this issue, so ensuring that the pressure is at the correct level is essential. You can refer to your boiler manual for instructions on how to check and adjust the water pressure. Once you have confirmed that the water pressure is adequate, reset the boiler and see if the fault code clears. If the F13 code persists, it may be time to call a professional engineer for further assistance.

Another possible cause of the F13 Glow Worm boiler fault is a faulty pump or circulation issue. If you suspect that this may be the case, it’s best to leave the repairs to a qualified engineer. They will be able to diagnose the problem accurately and carry out any necessary repairs or replacements. Trying to fix a pump or circulation issue yourself can be dangerous, so it’s always best to seek professional help when dealing with these components.

If all else fails and you are still seeing the F13 fault code on your Glow Worm boiler, it may be a sign of a more serious underlying issue. In this case, it’s crucial to contact a Gas Safe registered engineer immediately. They will be able to conduct a thorough inspection of your boiler and determine the root cause of the fault. Remember, safety should always come first when dealing with boiler issues, so don’t hesitate to seek professional help if you are unsure.

Shine a Light on Troubleshooting Tips for Your F13 Glow Worm Boiler

In addition to checking the water pressure and inspecting the pump, there are a few other troubleshooting tips you can try to fix the F13 Glow Worm boiler fault. One simple yet effective tip is to ensure that the condensate pipe is not frozen or blocked. A blocked condensate pipe can cause the boiler to shut down and display the F13 fault code. You can try thawing the pipe using warm water or a hot water bottle to see if this resolves the issue.

Another troubleshooting tip is to check the boiler’s flue for any obstructions or blockages. A blocked flue can prevent the boiler from functioning properly and may trigger the F13 fault code. Clearing any debris or obstructions from the flue may help resolve the issue. Additionally, checking the boiler’s ventilation to ensure that it is not restricted can also help prevent the F13 fault code from appearing.

If you have tried all the troubleshooting tips mentioned above and the F13 fault code still persists, it’s time to seek professional help. A qualified engineer will have the knowledge and expertise to diagnose and repair any complex issues with your Glow Worm boiler. Remember, regular maintenance and servicing are key to keeping your boiler in top condition and preventing future faults from occurring.


In conclusion, dealing with an F13 Glow Worm boiler fault may seem daunting, but with the right troubleshooting tips and professional help, you can get your boiler back in working order in no time. Remember to prioritize safety and always consult a qualified engineer if you are unsure about any repairs.
