What does the Ideal Mexico HE F41 fault code mean?
The F41 fault code on the Ideal Mexico HE indicates a system pressure fault, which typically means that the boiler’s water pressure is either too low or too high. This can affect the boiler’s ability to operate efficiently and safely.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system, a faulty pressure relief valve, or insufficient water supply.
- High Water Pressure: This may be caused by a malfunctioning pressure regulator or expansion vessel failure.
Can I fix it myself? (DIY)
If the issue is low water pressure, you can attempt to repressurise the system by using the filling loop. However, if you suspect high pressure or any gas/electrical issues, it is crucial to call a Gas Safe Engineer for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing a pressure fault on the Ideal Mexico HE is around £150 to £250. This includes potential replacement of components like the pressure relief valve or expansion vessel, which are common culprits for pressure issues.
