Worcester EA Fault Code – What It Means & How to Fix It
The Worcester EA fault code signals a flame detection problem, often caused by a frozen condensate pipe, gas supply issues, or a faulty flame sensor. You can try resetting the boiler, checking your gas supply, or defrosting the condensate pipe. If the issue persists, it’s best to call a Gas Safe registered engineer. This code affects models like the Greenstar i, Si, and CDi range. Regular servicing can help prevent this common boiler fault.

What Is the Worcester EA Fault Code?
The EA code on a Worcester Bosch boiler indicates a flame detection error. This means the boiler is failing to detect a flame, preventing it from heating water. It often results in a lockout for safety reasons.
Quick Checks Before Calling an Engineer
Time needed: 5 minutes
Try these simple steps first:
- Reset the Boiler
Press and hold the reset button for 5 seconds. You may need to try this more than once.
- Check Gas Supply
Make sure the gas valve is fully open. If on a prepay meter, ensure you have credit.
- Test Other Gas Appliances
Turn on the gas hob or fire. If they don’t work, call the National Gas Emergency Service.
- Check for Frozen Condensate Pipe
During cold weather, pour warm water over the pipe to defrost it if it’s blocked.
If these steps don’t resolve the issue, contact a Gas Safe registered engineer.
Why the EA Fault Happens
- Flame failure due to gas supply issues
- Frozen or blocked condensate pipe
- Faulty flame sensor or ignition
- Malfunctioning PCB (Printed Circuit Board)
The PCB detects internal errors and triggers a lockout to protect the boiler. Persistent EA codes often point to a deeper fault needing professional attention.
Which Worcester Bosch Boilers Show EA Error Code?
The EA fault code can appear on models such as:
- Greenstar i Series
- Greenstar Si
- Greenstar CDi Highflow & Classic
- Greenstar CDi Fi & Regular
Still Having Issues?
If your boiler is old, poorly maintained, or frequently breaking down, it may be time for a replacement. New Worcester Bosch boilers come with up to a 10-year guarantee and improved energy efficiency.
Conclusion
The Worcester Bosch EA fault code typically points to a flame detection issue often triggered by gas supply interruptions, a frozen condensate pipe, or a faulty sensor. While basic troubleshooting like resetting the boiler or checking the gas flow may resolve the problem, persistent errors should always be handled by a Gas Safe registered engineer.
Regular maintenance and annual servicing can help prevent these faults and extend your boiler’s lifespan. If your boiler is frequently showing error codes or struggling to perform, it may be time to consider a replacement.
For reliable diagnostics, repairs, or a new Worcester Bosch installation, contact a trusted professional or accredited installer to restore your heating and hot water with confidence.
Frequently Asked Questions
The 227 code, or EA fault code, appears when the boiler’s control system has made multiple attempts to ignite the burner, but no flame has been detected. Essentially, the system expects to sense a flame via the flame sensing electrode shortly after ignition: when this doesn’t happen, it raises an alert.
The Bosch error code EE indicates that your system’s modulating solenoid valve has been disconnected. This valve is important as it is involved in water temperature and pressure regulation.
