What does the Worcester Bosch Greenstar i F61 fault code mean?
The F61 fault code on the Worcester Bosch Greenstar i indicates a problem with the system water, often related to low water pressure or issues with the water quality. This can prevent the boiler from operating efficiently and may lead to further complications if not addressed promptly.
Common Causes
- Low Water Pressure: Insufficient water pressure in the system can trigger the F61 fault code, often due to leaks or insufficient filling.
- Water Quality Issues: Contaminated or poor-quality water in the system can affect the boiler’s performance and lead to this fault code.
Can I fix it myself? (DIY)
You can check the water pressure gauge on your boiler; if it is below 1 bar, you may need to top up the system using the filling loop. However, if you suspect water quality issues or if the problem persists, it is essential to call a Gas Safe Engineer for a thorough inspection.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F61 fault code could range from £100 to £250, depending on whether it involves simply repressurising the system or requires more extensive work such as flushing the system or replacing components affected by poor water quality.
