What does the Glow-worm Flexicom F67 fault code mean?
The F67 fault code on the Glow-worm Flexicom indicates a problem with the pilot burner, which may be failing to ignite or stay lit. This issue can prevent the boiler from operating efficiently, leading to heating and hot water supply problems.
Common Causes
- Blocked Pilot Injector: A blockage in the pilot injector can restrict gas flow, preventing the pilot from igniting.
- Faulty Thermocouple: If the thermocouple is malfunctioning, it may not detect the pilot flame, causing the boiler to shut down for safety reasons.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer for any issues related to the pilot burner, as working with gas appliances can be dangerous. Attempting to fix it yourself may void warranties and pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the F67 fault could range from £150 to £250, depending on whether the pilot injector needs cleaning or replacement, or if the thermocouple requires servicing. This cost reflects the complexity of the repair and the need for a qualified technician.
