What does the Ideal Mexico HE F70 fault code mean?
The F70 fault code on the Ideal Mexico HE indicates a central heating ignition fault, which means the boiler is unable to ignite the burner for the central heating system. This can lead to a lack of heating and hot water in the property.
Common Causes
- Blocked Flue: A blockage in the flue can prevent the boiler from venting properly, leading to ignition failure.
- Faulty Ignition Electrode: If the ignition electrode is damaged or malfunctioning, it may not create the necessary spark to ignite the gas.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer for any gas or electrical issues, as working on boilers can be dangerous. However, you can check the pressure gauge and reset the boiler if the pressure is low.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F70 fault could range from £150 to £300, depending on whether the issue is a simple reset or requires replacement parts like an ignition electrode or flue cleaning.
