What does the Ideal Mexico HE F32 fault code mean?
The F32 fault code on the Ideal Mexico HE indicates a high temperature limit fault, which means the boiler has detected that the water temperature has exceeded safe operating limits. This safety feature is designed to prevent overheating and potential damage to the system.
Common Causes
- Blocked Heat Exchanger: A buildup of debris or limescale can restrict water flow, causing the temperature to rise excessively.
- Faulty Thermostat: If the thermostat is malfunctioning, it may not accurately read the water temperature, leading to overheating.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and fix this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing an F32 fault could be around £150 to £250, primarily depending on whether the heat exchanger needs cleaning or replacement, or if the thermostat requires servicing.
