What does the Ideal Logic Plus F43 fault code mean?
The F43 fault code on the Ideal Logic Plus indicates a problem with the condensate trap, which may be blocked or malfunctioning. This can prevent proper drainage of condensate, leading to boiler shutdown to avoid damage.
Common Causes
- Blocked condensate trap: Debris or ice may obstruct the trap, preventing water from draining properly.
- Faulty trap mechanism: The internal components of the trap may be damaged or worn out, causing it to fail in its function.
Can I fix it myself? (DIY)
While you can check for blockages in the condensate trap and clear them if accessible, it is strongly advised 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 an Ideal Logic Plus boiler is approximately £150 to £200. This includes parts and labour, reflecting the complexity of the task and the need for a qualified engineer.
