What does the Ideal Logic Plus F23 fault code mean?
The F23 fault code on the Ideal Logic Plus indicates a flame failure, meaning the boiler is unable to detect a flame when it attempts to ignite. This can prevent the boiler from operating, leading to a lack of heating and hot water.
Common Causes
- Blocked Flue: A blockage in the flue can prevent proper ventilation, causing the boiler to fail to ignite.
- Faulty Flame Sensor: If the flame sensor is dirty or malfunctioning, it may not detect the flame, leading to a shutdown.
Can I fix it myself? (DIY)
While some issues may be resolved by checking and cleaning the flame sensor, it is crucial to call a Gas Safe Engineer for any gas or electrical problems to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for a faulty flame sensor is around £120, which includes parts and labour. This is based on the typical cost of the sensor and the time required for a qualified engineer to replace it.
