What does the Glow-worm Betacom F62 fault code mean?
The F62 fault code indicates a problem with the central heating outlet temperature, suggesting that the boiler is unable to achieve or maintain the required temperature for the heating system. This can lead to inadequate heating performance and may require immediate attention.
Common Causes
- Faulty Temperature Sensor: The temperature sensor may be malfunctioning, providing incorrect readings to the boiler’s control system.
- Blocked Heat Exchanger: A blockage in the heat exchanger can prevent proper heat transfer, leading to 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 can be dangerous if handled improperly. Attempting repairs without proper training can lead to further damage or safety hazards.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F62 fault could range around £150 to £250, primarily depending on whether the temperature sensor needs replacement or if the heat exchanger requires cleaning or servicing.
