What does the Ideal Mexico HE F93 fault code mean?
The F93 fault code on the Ideal Mexico HE boiler indicates a domestic hot water (DHW) reset fault. This typically means that the boiler has failed to provide hot water due to a malfunction in the DHW system.
Common Causes
- Faulty DHW Sensor: A malfunctioning sensor can prevent the boiler from accurately detecting water temperature, leading to a reset fault.
- Blocked Heat Exchanger: A blockage in the heat exchanger can restrict water flow, causing the boiler to fail in heating the water properly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional handling. Attempting DIY repairs could be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F93 fault could range around £150 to £300, depending on whether the issue is with the DHW sensor or the heat exchanger. Replacement parts and labour costs contribute to this estimate.
