Boiler fault codes can be confusing and intimidating, but they are essential for diagnosing and fixing issues with your heating system. Understanding these codes can help you troubleshoot problems more effectively and ensure your boiler runs smoothly. Here’s a guide to some common Worcester Bosch boiler fault codes and what they mean.
Five Worcester Bosch Boiler Fault Codes
1. EA – Flame Detection Error
The EA code indicates that the boiler is not detecting a flame. This can be caused by issues with the gas supply, ignition system, or flame sensor. First, check that your gas supply is turned on and there are no interruptions. If the gas supply is fine, the problem may lie with the ignition electrodes or the flame sensor, which may need cleaning or replacement.

2. A7 – Flow Temperature Sensor Fault
An A7 code suggests a problem with the flow temperature sensor, which monitors the temperature of the water flowing through the boiler. This could be due to a faulty sensor or a wiring issue. To fix this, you might need to replace the sensor or check the wiring connections. Understanding these faults can help improve your boiler’s efficiency; learn more on our Low Boiler Efficiency page.
3. C1 264 – Fan Fault
The C1 264 code points to a fault with the boiler’s fan, which is crucial for removing exhaust gases safely. A malfunctioning fan can cause the boiler to shut down as a safety measure. Check if the fan is obstructed or damaged and ensure it is receiving power. Regular maintenance can help prevent such issues; read more in our Late Summer and Early Autumn Boiler Servicing article.
4. E9 – Overheating
The E9 code indicates that the boiler is overheating. This can be due to a blocked heat exchanger, low water pressure, or a faulty pump. First, check the water pressure and ensure it is within the recommended range. If the pressure is adequate, the heat exchanger may need cleaning to remove any blockages.

5. F1 – Ignition Failure
The F1 code signifies an ignition failure, which can be caused by several factors, including gas supply issues, faulty ignition leads, or a defective gas valve. Ensure that your gas supply is uninterrupted and check the condition of the ignition leads. If these components are in good condition, the gas valve may need inspection or replacement.
Understanding these fault codes can help you troubleshoot and resolve issues more efficiently. Always refer to your boiler’s manual for specific guidance and consult a professional if you’re unsure or unable to fix the problem yourself. Regular maintenance and timely repairs are key to keeping your boiler in top condition.
