What does the Baxi EcoBlue E160 fault code mean?
The E160 fault code on the Baxi EcoBlue indicates that the boiler has exceeded its high temperature limit, which can lead to overheating and potential damage. This safety feature is designed to protect the boiler from operating under unsafe conditions.
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 temperature, leading to overheating.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair the issue, as working on gas appliances can be dangerous. However, you can check the pressure gauge and reset the boiler if the pressure is low.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E160 fault could range from £150 to £300, depending on whether the heat exchanger needs cleaning or replacement, or if the thermostat requires servicing. This estimate includes labour and parts.
