What does the Glow-worm Energy F61 fault code mean?
The F61 fault code on the Glow-worm Energy boiler indicates a domestic hot water (DHW) control fault. This typically means there is an issue with the boiler’s ability to manage the hot water supply, which may affect performance and efficiency.
Common Causes
- Faulty DHW Sensor: A malfunctioning sensor can prevent the boiler from accurately detecting water temperature, leading to control issues.
- Wiring Issues: Damaged or loose wiring connections between the control board and the DHW components can disrupt communication and functionality.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer for any repairs related to gas or electrical components. Attempting to fix these issues without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F61 fault could be around £150 to £250, depending on whether the DHW sensor needs replacement or if wiring repairs are required. This cost reflects the complexity of diagnosing and fixing electronic control issues.
