What does the Glow-worm Flexicom F48 fault code mean?
The F48 fault code on a Glow-worm Flexicom boiler indicates a problem with the condensate trap, which may be blocked or malfunctioning. This can prevent the proper drainage of condensate, leading to operational issues with the boiler.
Common Causes
- Blocked condensate trap: Debris or sludge accumulation can obstruct the flow of condensate, causing the fault code to trigger.
- Faulty trap mechanism: The internal components of the condensate trap may be damaged or worn out, preventing it from functioning correctly.
Can I fix it myself? (DIY)
While some homeowners may attempt to clear a blocked condensate trap, it is highly recommended to call a Gas Safe Engineer for any repairs or replacements to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated cost to repair or replace a faulty condensate trap on a Glow-worm Flexicom boiler is approximately £150 to £250. This includes parts and labour, reflecting the typical costs for a qualified engineer to address the issue.
