What does the Baxi 600 Series E370 fault code mean?
The E370 fault code on the Baxi 600 Series indicates a failure to ignite the domestic hot water (DHW) system. This issue can prevent the boiler from providing hot water, which can be inconvenient and may require immediate attention.
Common Causes
- Blocked Flue: A blockage in the flue can prevent the boiler from venting properly, leading to ignition failure.
- Faulty Ignition Electrode: If the ignition electrode is damaged or malfunctioning, it may not create the spark needed to ignite the gas.
Can I fix it myself? (DIY)
It is advised to call a Gas Safe Engineer for any gas or electrical issues, as attempting to fix these problems without proper training can be dangerous. However, you can check the boiler pressure and reset the boiler if necessary.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E370 fault could be around £150 to £250, depending on whether the ignition electrode needs replacement or if there are flue issues that require attention.
