What does the Baxi Megaflo E200 fault code mean?
The E200 fault code on a Baxi Megaflo indicates that the system pressure is too high, which can lead to potential damage or inefficiency in the boiler’s operation. It is crucial to address this issue promptly to ensure the safe and effective functioning of the heating system.
Common Causes
- Overfilled System: The system may have been overfilled during maintenance or due to a malfunctioning pressure relief valve.
- Faulty Pressure Relief Valve: A defective pressure relief valve can fail to release excess pressure, causing the system to exceed safe levels.
Can I fix it myself? (DIY)
If you are familiar with boiler systems, you can try to reduce the pressure by bleeding radiators or using the pressure gauge to release some water. However, if you are unsure or if the issue persists, it is strongly advised to call a Gas Safe Engineer to avoid any safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E200 fault code could range around £150 to £250, depending on whether the issue is a simple adjustment or requires replacement of a faulty pressure relief valve, which typically costs around £100 to £150 including labour.
