What does the Ideal Mexico HE F25 fault code mean?
The F25 fault code on the Ideal Mexico HE indicates an ignition failure, meaning the boiler is unable to ignite the gas to start the heating process. This can lead to a lack of hot water and heating in the property.
Common Causes
- Faulty Ignition Electrode: The ignition electrode may be damaged or dirty, preventing it from creating a spark to ignite the gas.
- Gas Supply Issues: There may be a blockage or interruption in the gas supply, which can prevent the boiler from igniting properly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas or electrical issues, as working on these systems can be dangerous. However, you can check the boiler pressure and reset the boiler if needed, following the manufacturer’s instructions.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F25 fault could be around £150 to £250, depending on whether the ignition electrode needs replacing or if there are gas supply issues that require attention.
