What does the Baxi Megaflo E700 fault code mean?
The E700 fault code on a Baxi Megaflo indicates a central heating (CH) system maintenance fault. This typically suggests that there is an issue requiring attention to ensure the proper functioning of the heating system.
Common Causes
- Low Water Pressure: Insufficient water pressure in the system can trigger this fault code, often due to leaks or insufficient filling.
- Blocked Filters: Clogged filters or strainers can restrict water flow, leading to system inefficiencies and triggering maintenance alerts.
Can I fix it myself? (DIY)
It is advisable to check the water pressure and ensure it is within the recommended range (usually between 1-1.5 bar). If the pressure is low, you can top it up using the filling loop. However, for any gas or electrical issues, it is crucial to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E700 fault could range around £150-£250, primarily depending on whether the issue is low pressure or requires cleaning/replacing filters. This estimate includes labour and potential parts needed for the repair.
