What does the Baxi Megaflo E570 fault code mean?
The E570 fault code on a Baxi Megaflo indicates a problem with the domestic hot water (DHW) system supply. This could be due to issues with water flow, temperature sensors, or other components affecting the hot water delivery.
Common Causes
- Blocked Water Supply: A blockage in the water supply line can restrict flow, leading to the E570 fault.
- Faulty Temperature Sensor: If the temperature sensor is malfunctioning, it may incorrectly signal a supply fault.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any repairs related to gas or electrical components. However, you can check for blockages in the water supply and ensure that the system is properly pressurized.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E570 fault could be around £150 to £250, depending on whether a temperature sensor replacement or blockage clearing is required. This estimate includes parts and labour for a qualified engineer.
