What does the Baxi 600 Series E710 fault code mean?
The E710 fault code indicates a failure to ignite the domestic hot water (DHW) system in the Baxi 600 Series boiler. This issue can prevent hot water from being produced, affecting your daily needs.
Common Causes
- Blocked Flue: A blockage in the flue system can restrict airflow, preventing proper combustion and ignition.
- Faulty Ignition Electrode: If the ignition electrode is damaged or dirty, it may fail to create a spark necessary for ignition.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas or electrical issues, as working on these systems 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 resolving the E710 fault could be around £150 to £250, depending on whether the issue is a simple cleaning or requires replacement of parts like the ignition electrode.
