What does the Glow-worm Energy F37 fault code mean?
The F37 fault code on a Glow-worm Energy boiler indicates a sensor fault, typically related to the temperature or pressure sensors within the system. This fault can prevent the boiler from operating efficiently or safely, requiring attention to restore functionality.
Common Causes
- Faulty Temperature Sensor: A malfunctioning temperature sensor can provide incorrect readings, leading to the F37 fault code being triggered.
- Wiring Issues: Damaged or loose wiring connections to the sensor can disrupt communication between the sensor and the boiler’s control board, causing the fault.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as working with boiler sensors and electrical components can be dangerous. Attempting repairs without proper training may lead to further complications or safety hazards.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F37 fault code is around £150 to £250, depending on whether the sensor needs replacing or if wiring repairs are required. This estimate includes parts and labour for a qualified engineer.
