Worster Bosch is one of the most reliable boilers in the UK. However, like any other tool, they can develop errors over time. However, the Worcester boilers show the error code to help users recognize problems quickly.
Moreover, understanding these error codes can save you time, money, and stress. So, this guide is the most common Worcester boiler error code, their causes, and how to cure them.
Worcester Boiler Fault Codes
When there is a problem, the Worcester boiler will show an error code on the screen. Moreover, each code matches a specific problem. Some problems require professional help, while others have simple improvements.
Common Worcester Boiler Fault Codes and Fixes
1. EA – No Flame Detected
This code appears when the boiler fails to light. First, check if your gas supply works. Try other gas units in your home. If they also do not work, you may have a supply problem.
To see it restart the kettle if the code disappears. However, if the problem persists, you can call the throttle engineer to inspect the ignition system.
2. E9 – Overheating Issue
The E9 error code indicates that the boiler is overheated. This may be due to a deficient pump, blocked heat exchanger, or low water pressure. First, check the pressure gauge.
If it is below once, try to top the water using the filling loop. However, bleeding radiators can also help remove stranded air. Moreover, if the problem continues, a professional should check the pump and heat exchanger.
3. A1 – Low Water Pressure
Low water pressure with the Worcester boiler is a common question. Check the pressure gauge. If it is below once, increase the pressure by opening the filling loop until it reaches between 1 and 1.5 times.
However, if the pressure falls, the system may leak. Call an engineer if you suspect a leak.
4. C6 – Fan Speed Error
The fan of the boiler helps you remove harmful gases. If it moves very quickly or very slowly, the boiler will display the C6 error code.
This can be caused by a deficient fan, wiring problem or blocked grip. However, to return the boiler can remove the error. If not, an engineer should check his fan and wires.
5. D5 – Issue with Boiler Sensor
The D5 Dosha code usually indicates a problem with the boiler temperature sensor. It can be deficient or incorrectly distributed. However, this problem requires professional attention. A heating engineer can test the sensor and can change it if necessary.
6. H07 – Low Gas Pressure
Low gas pressure prevents the boiler from working efficiently. This can be caused by problems with the gas supply, frozen pipes, or error gas valves.
Check if other gas appliances work in your house. If not, contact your gas supplier. However, if the problem is with the boiler, an engineer should check the gas valve and pipe.
7. F0 – Internal Memory Fault
This error occurs when the boiler’s software does not work. A simple reset can solve the problem. Press the Reset button for five seconds. However, if the error persists, the boiler may require software updates or replacement of control cards.
8. F7 – Flame Detection Issue
The boiler’s flame sensor reveals if the burner works. If the sensor fails, the boiler will show F7 errors. To see this, the kettle restarts whether it cleans the code. However, if the problem continues, an engineer should inspect the flame sensor and ignition system.
9. F9 – Water Pressure Sensor Fault
This fault means that the boiler cannot detect the water pressure properly. This may be caused by a blocked sensor or a wiring error. However, try to reset the kettle. If he does not work, a professional should inspect and possibly change the sensor.
10. E5 – Flow Temperature Sensor Error
The E5 code indicates a problem with temperature sensors that monitors the water flow. This can happen when the sensor is distributed deficient or incorrect. Resetting the boiler can solve the problem. If not, an engineer should check the sensor and wires.
11. E2 – Ignition Lockout
An E2 error means that the boiler has repeatedly closed due to ignition failure. This can be caused by problems with gas supply, deficient ignition lines or blocked burners. Check your gas supply and reset the boiler. If the problem persists, you can call Gas Safe Engineer.
12. E1 – System Pressure Too High
The boiler pressure should be between 1 and 1.5 times. To reduce the pressure does not read a radiator meter normal until the meter is normal. If the problem occurs often, an engineer should examine the defective components.

Preventing Worcester Boiler Issues
Many boiler faults can be prevented with regular maintenance. Here are some simple steps:
- Check boiler pressure: Keep it between 1 and 1.5 bar.
- Bleed radiators: Remove trapped air to ensure even heating.
- Schedule annual servicing: A professional service can detect issues early.
- Keep the flue clear: Make sure there are no obstructions.
- Insulate external pipes: Prevents freezing in winter.
When to Call a Professional
Some boilers can be fixed with a reset or pressure adjustment. However, if you notice leaks, unusual noise, or repeated closures, you can contact a qualified engineer. Problems related to gas should always be controlled by a gass-safe registered professional.
Conclusion
Worcester boilers are reliable, but they can develop errors over time. Understanding the error code can help you diagnose problems quickly. Some problems, such as low pressure, can be easily determined.
Others, such as incorrect sensors or problems with gas supply, require professional help. Regular maintenance is the best way to run the boiler smoothly. If there is any doubt, always seek expert advice to ensure that your heating system remains safe and efficient.
Frequently Asked Questions
Boiler fault codes are alphanumeric messages that indicate specific issues in the system, helping with quick diagnosis and troubleshooting.
It’s a display that shows error codes when the boiler detects a problem, guiding users or engineers to the fault.
Common faults include no flame (EA), low pressure (A1), overheating (E9), ignition issues (E2), and sensor faults (F7, D5).
Press and hold the Reset button for 5 seconds. If the fault returns, consult an engineer.
