What does the Baxi 600 Series E260 fault code mean?
The E260 fault code indicates a problem with the domestic hot water (DHW) temperature being below the expected level. This can lead to insufficient hot water supply for taps and showers.
Common Causes
- Thermostat Malfunction: A faulty thermostat may not be accurately reading the water temperature, preventing the boiler from heating the water sufficiently.
- Heat Exchanger Issues: A blockage or scaling in the heat exchanger can restrict the flow of water, leading to inadequate heating of the domestic hot water.
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 to fix these could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E260 fault could range from £150 to £300, depending on whether the thermostat needs replacing or if the heat exchanger requires cleaning or replacement.
