What does the Ideal Mexico HE F67 fault code mean?
The F67 fault code on the Ideal Mexico HE indicates a domestic hot water (DHW) control fault, which typically means there is an issue with the boiler’s ability to heat water for taps and showers. This can lead to inadequate hot water supply or fluctuations in temperature.
Common Causes
- Faulty DHW Sensor: A malfunctioning sensor may not accurately detect water temperature, causing control issues.
- Wiring Issues: Damaged or loose wiring connections can disrupt communication between components, leading to control faults.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any repairs related to gas or electrical components. Attempting to fix these issues without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the F67 fault could be around £150 to £250, primarily depending on whether the DHW sensor needs replacement or if wiring repairs are necessary. This estimate includes parts and labour.
