What does the Glow-worm Betacom F29 fault code mean?

Common Causes
- Faulty Flame Sensor: The flame sensor may be dirty or malfunctioning, preventing it from detecting the flame accurately.
- Gas Supply Issues: Insufficient gas supply or pressure can lead to the flame not being established, triggering the fault code.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and fix this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F29 fault could be around £150 to £250, primarily depending on whether the flame sensor needs cleaning or replacement, as well as any necessary adjustments to the gas supply.
