Worcester Bosch boilers are known for their reliability and efficiency, making them a popular choice for homeowners across the UK. However, like any complex system, boilers can occasionally experience issues. When something goes wrong, your Worcester Bosch boiler will display a fault code on its control panel. These codes are designed to help identify the problem, but understanding what they mean can be tricky if you’re not familiar with boiler systems.
In this blog post, we’ll take a closer look at some common Worcester Bosch fault codes, what they mean, and what actions you should take when you see them. While some minor issues can be resolved without professional help, many situations require the expertise of a qualified heating engineer to ensure your boiler is working safely and efficiently.

Understanding Worcester Bosch Fault Codes
Worcester Bosch boilers are fitted with advanced diagnostic systems to help you and your heating engineer identify and fix issues quickly. When a problem occurs, a fault code will appear on the display screen, which helps pinpoint the exact nature of the problem.
Below are some of the most common fault codes and what they indicate.
Worcester Bosch Fault Code EA
Problem: No Flame Detected
This fault code indicates that the boiler is not detecting a flame. The most likely causes of this are issues with the gas supply or a problem with the ignition system. It could also be caused by a blocked condensate pipe or frozen pipes during winter.
What to Do:
- First, check your gas supply. Is the gas turned on, and are other gas appliances in your home working?
- If it’s during the winter, check the condensate pipe to see if it’s frozen. Defrosting it could solve the problem.
- If the issue persists, it’s best to call a qualified heating engineer to inspect and repair your boiler.
Worcester Bosch Fault Code E9
Problem: Overheating
The E9 fault code indicates that the boiler is overheating. This is a serious issue that should not be ignored as it could cause significant damage to the boiler and poses a potential safety risk. Overheating can be caused by a blocked heat exchanger, low water pressure, or faulty circulation.
What to Do:
- Check the pressure gauge on your boiler. If it’s too low, you may need to re-pressurise the system.
- If the pressure is correct and the problem persists, you should turn off the boiler and contact a heating engineer immediately.
Worcester Bosch Fault Code A1
Problem: Low Water Pressure
If you see the A1 fault code, it usually means that your boiler has low water pressure. This can happen if there’s a leak in the system or if air has become trapped in the radiators.
What to Do:
- Check the pressure gauge on the front of your boiler. If it’s below 1 bar, you’ll need to top up the pressure using the filling loop.
- If you’re unsure how to do this, or if topping up the pressure doesn’t resolve the issue, it’s time to call a heating engineer. They can check for leaks or other underlying problems that may be causing the pressure to drop.
Worcester Bosch Fault Code C6
Problem: Fan Error
The C6 fault code relates to an issue with the boiler’s fan. The fan is essential for clearing harmful gases from the boiler’s combustion chamber, so if it’s not working properly, the boiler will not operate. This could be due to a mechanical failure or a wiring issue.
What to Do:
- This is not a fault you can resolve yourself. You’ll need to contact a qualified heating engineer who can diagnose the problem and replace the fan if necessary.
When to Call a Heating Engineer
While some fault codes can be fixed by checking your gas supply or re-pressurising the system, many faults require professional intervention. If your boiler displays any of the following symptoms alongside a fault code, it’s important to seek expert help:
- Persistent error messages that don’t clear after a reset
- Strange noises coming from the boiler, such as banging or whistling
- Leaking water around the boiler unit
- Boiler turning off unexpectedly or not starting at all
Attempting to fix more complex issues yourself could cause further damage or void your boiler’s warranty. That’s why it’s always best to leave more complicated repairs to the professionals.
