What does the Worcester Bosch Greenstar Si F97 fault code mean?
The F97 fault code indicates a maintenance issue within the heating system, often related to the system’s pressure or a lack of proper servicing. This can lead to inefficient operation or potential damage if not addressed promptly.
Common Causes
- Low System Pressure: Insufficient water pressure in the heating system can trigger this fault code, often due to leaks or insufficient filling.
- Lack of Regular Maintenance: Failure to perform routine servicing can lead to various issues, including blockages or component wear, resulting in the F97 error.
Can I fix it myself? (DIY)
If you are comfortable with basic plumbing tasks, you can check the system pressure and top it up if it’s low. However, for any gas or electrical issues, it is crucial to call a Gas Safe Engineer to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F97 fault could range from £100 to £250, depending on whether it requires a simple pressure adjustment or more extensive maintenance work, such as flushing the system or replacing components.
