What does the Glow-worm Flexicom F61 fault code mean?
The F61 fault code on a Glow-worm Flexicom boiler indicates a problem with the flue gas temperature sensor, which may be reading incorrectly. This can lead to the boiler shutting down to prevent overheating and potential damage.
Common Causes
- Faulty Flue Gas Temperature Sensor: The sensor may be malfunctioning or damaged, causing inaccurate readings.
- Blocked Flue: A blockage in the flue system can prevent proper ventilation, leading to abnormal temperature readings.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer to diagnose and repair this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the F61 fault could range around £150 to £250, primarily depending on whether the flue gas temperature sensor needs replacing or if there are additional issues with the flue system.
