When your Worcester Bosch boiler shows the EA 227 error code, it indicates a no ignition fault, meaning the boiler has failed to ignite safely. At 0800 Homefix, we frequently deal with ignition-related issues such as the Worcester EA 227 fault to ensure safe and consistent boiler performance.
A ‘Worcester error’ is a common term used to describe error codes that appear on Worcester Bosch boilers, helping users identify specific problems. The EA 227 fault is just one of several boiler issues that can affect ignition and overall boiler performance.
This guide breaks down the error, highlights its possible causes, and explains how our engineers resolve this fault quickly and safely.
What Is the Worcester EA 227 Fault Code?
The EA 227 code is a specific type of EA fault, representing a failure during the ignition phase. It usually occurs after three unsuccessful attempts to ignite the gas burner. The EA 227 is one of several fault codes that can appear on Worcester boilers, each indicating different issues that may affect performance and safety.

The EA 227 is a common Worcester boiler fault that many users search for when experiencing ignition problems.
The error is commonly found on Worcester Greenstar, CDi Compact, and i System models. Fault code 227 typically points to an issue with flame detection or ignition, and ignition failure is among the most frequent errors encountered in Worcester Bosch boilers.
Common Causes of EA 227 Error
Common culprits for the EA 227 error include:
-
No gas supply / Gas supply problems / Gas supply issues: A closed valve, interruption in mains gas, issues with the gas meter, external gas meter, frozen gas meter, gas regulator, or general gas supply problem will prevent ignition by restricting gas flow to the boiler.
-
Faulty gas valve / Gas valves: If the gas valve is stuck, improperly adjusted, or fails to open or modulate properly, gas won’t reach the burner, causing ignition failure. This is especially common in an old boiler or older boilers.
-
Ignition electrode failure / Ignition lead: A worn, damaged, or faulty ignition lead or spark electrode cannot ignite gas, leading to repeated ignition failures.
-
Flame detection failure / Flame sensing electrode / Faulty flame sensing electrode / Flame signal / Faulty flame: The boiler doesn’t detect a flame even if ignition occurs, often due to a faulty flame sensing electrode, weak or missing flame signal, or a faulty flame. This can trigger error codes if the flame is not detected.
-
Pilot jet / Blocked pilot jet / Flame flickering: A blocked pilot jet or dirty pilot jet can cause flame flickering, weak ignition, or failure to ignite. Debris or dirt in the pilot jet or burner is a common cause.
-
Condensate blockages / Frozen condensate pipe: Water or ice in the condensate pipe, especially during cold weather, can halt ignition sequences. Ensuring the pipe is properly insulated and using warm water to thaw it can help prevent freezing and keep the boiler functioning correctly.
-
PCB faults / Damaged PCB / Printed circuit board / Electrical components / Moisture buildup / Tiny leak / Even a tiny leak / Heat exchanger / Water supply: Miscommunication between components may block the ignition process. Moisture buildup from even a tiny leak in the heat exchanger or water supply can damage electrical components like the printed circuit board, leading to serious problems and costly repairs.
These issues can affect all types of boilers, including Worcester Bosch boilers, Worcester boilers, and combi boilers.
Cold weather can cause a frozen condensate pipe, leading to ignition problems. Using warm water to thaw the pipe and ensuring it is properly insulated can help prevent freezing and keep your boiler functioning properly.
Even a tiny leak or moisture buildup inside the boiler can damage sensitive electrical components such as the printed circuit board or heat exchanger, resulting in serious problems and fault codes.
The boiler will make several attempts to ignite, and if no flame is detected, it will enter safety lockout mode to prevent further issues and ensure safe operation. If the boiler fires after resolving the issue, it indicates the problem has been fixed.
Signs of the EA 227 Fault
-
Display shows EA 227 error or alternates with “Reset” prompt
-
Boiler attempts to start, then shuts down
-
No heating or hot water output
-
Audible clicking (attempts to ignite) without flame – the boiler fails to detect a flame signal, so operation is prevented
-
Flame flickering may be observed at the burner or pilot jet, indicating an underlying issue with flame stability or detection
These symptoms indicate that the boiler is not running smoothly and requires attention.
First Steps You Can Take
Before calling an engineer, consider these safe checks:
-
Confirm the gas supply is on (test another gas appliance)
-
Reset the boiler once using the front panel
-
Check if the condensate pipe is frozen or blocked
If these steps do not resolve the issue, seek professional assistance from a qualified professional, such as a certified professional boiler engineer or gas safety engineer. Persistent faults may require professional Worcester Bosch repair to ensure safety and compliance.
⚠️ Further inspection should only be done by a Gas Safe registered engineer.
How 0800 Homefix Can Help
Our engineers can resolve the Worcester EA 227 fault using a systematic diagnostic process:
-
Test and replace the ignition electrodes
-
Examine the gas valve for operation and leaks
-
Inspect and clear the condensate trap and pipework
-
Confirm PCB function and communication with other components
-
Ensure safe ignition and proper flame monitoring
Labour costs for repairs can vary depending on the complexity of the issue and the time required by the boiler engineer. A professional boiler engineer or gas safe boiler engineer will carry out the repair to ensure safety and compliance.
We carry replacement parts for Worcester Bosch ignition systems, enabling most repairs on the first visit. 0800 Homefix also offers regular maintenance and Worcester Bosch repair services to keep your boiler in top condition.
Preventing No Ignition Faults in the Future
-
Book an yearly boiler servicing and perform regular maintenance to clean electrodes and test sensors
-
Use frost protection kits for external condensate pipes
-
Address low gas pressure concerns early
-
Watch for intermittent resets or ignition failures don’t ignore them
Regular maintenance helps prevent serious problems and keeps your boiler running smoothly.
FAQs
What does EA 227 mean on a Worcester boiler?
EA 227, also known as fault code 227, means the boiler has failed to ignite the gas after multiple attempts and has entered lockout mode. This fault code is common on Worcester Bosch boilers and can also appear on other boilers, including combi boilers.
Can I fix the EA 227 fault myself?
You can try a reset and check your gas supply. Beyond that, the fix requires a Gas Safe engineer.
