What does the Worcester Bosch Greenstar Ri F32 fault code mean?
The F32 fault code indicates a flue gas temperature fault, which suggests that the boiler is detecting an abnormal temperature in the flue system. This could lead to inefficient operation or safety concerns, necessitating immediate attention.
Common Causes
- Blocked Flue: A blockage in the flue can prevent proper ventilation, causing the temperature to rise excessively.
- Faulty Temperature Sensor: A malfunctioning temperature sensor may incorrectly report the flue gas temperature, triggering the fault code.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that can be dangerous if handled improperly. Attempting DIY repairs could void your warranty and pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F32 fault could range from £150 to £300, depending on whether the issue is a blocked flue or a faulty sensor. If a sensor replacement is needed, the cost may be on the lower end, while extensive flue repairs could increase the price significantly.
