What does the Glow-worm Betacom F61 fault code mean?
The F61 fault code on the Glow-worm Betacom indicates a problem with the domestic hot water (DHW) outlet temperature, suggesting that the boiler is unable to maintain the required temperature for hot water delivery. This can lead to insufficient hot water supply for taps and showers.
Common Causes
- Faulty Temperature Sensor: The temperature sensor may be malfunctioning, causing incorrect readings and triggering the fault code.
- Blocked Heat Exchanger: A blockage in the heat exchanger can restrict water flow, preventing the boiler from heating water effectively.
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 to fix it yourself could be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F61 fault could be around £150 to £250, primarily depending on whether the temperature sensor needs replacing or if the heat exchanger requires cleaning or replacement.
