How to fix Baxi Megaflo fault code E760

What does the Baxi Megaflo E760 fault code mean?

The E760 fault code on a Baxi Megaflo indicates a central heating (CH) system service fault. This typically suggests that there is an issue with the heating system that requires attention to ensure proper operation.

Common Causes

  • Low Water Pressure: Insufficient water pressure in the system can trigger this fault code, preventing the boiler from functioning correctly.
  • Blocked Filters or Valves: Blockages in the system, such as dirty filters or closed valves, can restrict water flow and lead to service faults.

Can I fix it myself? (DIY)

If you are comfortable, check the pressure gauge on the boiler; it should be between 1-1.5 bar. If it’s 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 E760 fault could range around £150 to £250, primarily depending on whether the issue is low water pressure or requires cleaning/replacing filters or valves.
