What does the Glow-worm Betacom F41 fault code mean?
The F41 fault code on the Glow-worm Betacom indicates a central heating temperature fault, which suggests that the boiler is unable to detect the correct temperature of the heating system. This can lead to inefficient heating and potential system damage if not addressed promptly.
Common Causes
- Faulty Temperature Sensor: The temperature sensor may be malfunctioning, providing inaccurate readings to the boiler.
- Blocked or Dirty Heat Exchanger: A blockage in the heat exchanger can prevent proper heat transfer, causing temperature discrepancies.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional handling. Attempting DIY repairs could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F41 fault could be around £150 to £250, primarily depending on whether the temperature sensor needs replacement or if the heat exchanger requires cleaning or servicing.
