What does the Ideal Mexico HE F96 fault code mean?
The F96 fault code on the Ideal Mexico HE indicates a central heating (CH) lockout fault, which typically occurs when the boiler detects a fault that prevents it from operating safely. This may be due to issues with the system pressure, flow, or a component malfunction.
Common Causes
- Low Water Pressure: Insufficient water pressure in the system can trigger a lockout to prevent damage to the boiler.
- Faulty Pump: A malfunctioning circulation pump may fail to circulate water properly, leading to overheating and lockout.
Can I fix it myself? (DIY)
If you are comfortable, check the system pressure on the gauge; it should typically be between 1-1.5 bar. If it’s low, you can repressurise the system following the manufacturer’s instructions. However, for any gas or electrical issues, it is crucial to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing an F96 fault could be around £150-£250, depending on whether the issue is low pressure (which may only require a simple refill) or a faulty pump that would need replacement, which is more costly.
