Worcester Bosch boiler EA 227 fault code meaning, causes & how to fix it
Here’s the lowdown on Worcester Error 227 fault code due to the fact that Worcester boilers are one of most installed in the UK so it is likely that you or a Gas Safe registered engineer will have come across this issue or symbol.
So, find out here what the Worcester Bosch EA227 error code means, how it can be prevented, and when it should be addressed by a professional boiler engineer or if your old boiler needs replacing due to higher repair bills and running costs.
Does the Worcester 227 fault mean I need a new boiler?
Not straight away no, as if you have a newer Worcester Bosch boiler, you may still be under warranty, however, old boilers over ten years old become very inefficient, so if your boiler is starting to show error codes, it may be cheaper, in the long run, to save on repairs and your rising gas bills!

What does the Worcester Error 227 mean?
- This error code means that a Worcester Bosch boiler failed to detect a flame when it tried to ignite
- The safety protocols for your boiler will kick in after about four to five attempts at starting the boiler protecting your boiler and your home.
- Often during this, the boiler will lock out and not work.
What causes the Worcester Error 227?
There are many reasons your boiler might not detect a flame while trying to ignite, but here are the most common reasons why Worcester bosch boilers will show the EA 227 error code.
- Frozen condensate pipe
- Gas supply issue
- Frozen gas meter
- Blocked pilot jet
- Faulty flame sensor
- Moisture leak
Frozen condensate pipe
If your Worcester Bosch boiler is displaying the EA 227 error code, this typically indicates a problem with the boiler’s ignition, which could be caused by a frozen condensate pipe blockage among other issues.
Here’s how you can find out if a frozen condensate pipe might be the reason behind the EA 227 error code, in relation to your Worcester Bosch boiler:
- Find the Condensate Pipe: First, locate the condensate pipe. It’s usually a plastic pipe (often white or grey) that exits from the bottom of your boiler and leads outside to a drain. This pipe can freeze in cold weather, leading to the EA 227 error code.
- Check for Signs of Freezing: Feel the pipe for extreme coldness and look for visible frost. This is a strong indicator that the pipe is frozen.
What to do to fix this issue?
- Gently Thaw the Frozen Condensate Pipe: You can thaw the pipe by applying gentle heat. Wrap the frozen section with a hot water bottle, a heating pad, or warm cloths. Avoid using direct heat sources like blow torches as they can damage the pipe.
- Pour Warm Water Over the Pipe: Slowly pour warm water (not boiling) over the frozen part of the condensate pipe. This should help melt the ice inside. Be cautious not to use boiling water as it could crack the plastic pipe.
- Insulate the Condensate Pipe: To prevent future freezing, insulate the condensate pipe with foam pipe insulation. This is particularly important for the outdoor portion of the pipe.
- Reset the Boiler: After the condensate pipe has been thawed, you’ll likely need to reset your Worcester Bosch boiler to clear the EA 227 error code. Follow the manufacturer’s instructions for resetting your specific Greenstar boiler model.
What if this doesn’t work?
- Professional Assistance: If the pipe continues to freeze or if you’re unable to resolve the EA 227 error code on your own, you may need professional help. A qualified heating engineer can check for other causes of the error code and offer a permanent solution.
- Preventive Measures: Consider having a professional reroute the condensate pipe to an internal drain if freezes are frequent. Additionally, ensure your boiler receives regular maintenance to prevent issues that could lead to error codes.
It’s important to address a frozen condensate pipe promptly to prevent your boiler from shutting down, especially during cold weather. Always prioritise your safety and, when in doubt, seek professional advice.
The gas supply to the Worcester Bosch boiler is not working.
This EA error code is the most common error that can occur on a Worcester Bosch boiler, and it could be due to a defective or improperly adjusted gas valve.
Therefore to be sure, your Gas Safe engineer can determine whether a valve can or must be replaced if one of the more obvious reasons for your boiler not working does not fix the problem.

What does the Worcester 227 Fault mean?
This fault code can be described as “No flame detected” or “No ionization after ignition”.
The EA 227 code is usually displayed after the boiler fails to register a flame for at least four attempts, and this repetitive attempt ensures that it’s not intermittent.
This indicates that the component responsible for detecting a flame is unable to do so or has suffered a fault, and this faulty component is known as a flame-sensing electrode.
Gas Supply problem
The gas valve is responsible for controlling the flow. If it gets stuck, it can cause too little or too many gasses to enter the unit – this should be something that can be prevented by a Worcester boiler service every year.
You may have had repairs recently and the valve could have been incorrectly adjusted.
Older boilers are more likely to be faulty because of wear and tear, which can prevent them from moving freely.
An engineer can usually correct a gas valve that has been incorrectly installed.
Old boilers may have a way to free a stuck valve. However, it is common to replace the part if it becomes stuck again. If the valve is not functioning properly, this will also apply.
Gas valves cost vary by model. However, you can expect to pay between £100 and £300.
Frozen gas meter
Your external gas meter could be the problem as the gas regulator, and the supply of gas to your boiler could be affected by a partially or fully frozen gas meter.
If your meter is outside, ensure it is properly insulated and boxed in.
Your Gas Safe Engineer can help you with this.
They will also advise you on how to properly insulate your meters to keep them safe from the cold and prevent this problem from happening again.
Blocked Pilot Jet
Even the smallest debris can block the pilot light jet, preventing the flame from developing. A blocked pilot jet could cause a flickering light just before the pilot light goes out. If this is the case, your Gas Safe boiler engineer can clean the tiny jet and reset your error display.
Faulty Flame Sensing Electrode
In order to create a flame, your Worcester boiler must have a working electrode or ignition lead. Sometimes they can be repaired, but your Gas Safe Engineer will advise you on what to do. It might even be less expensive to replace them.
It is possible to clean a dirty sensor easily. If the sensor is damaged, however, it can be easily removed and cleaned.
The parts are usually less expensive than £100, so the labour costs for repair will likely be higher.
Moisture leaking into the electrical parts or components
The boiler houses many internal electrical components. Even the smallest leak or buildup of moisture can cause damage to these delicate components if you find a leak and see the Worcester boiler fault 227, shut off the water supply to the boiler.
The leak will most likely not be visible from the outside of the unit as it may be coming from your heat exchanger. It is best to have your engineer diagnose it.
The PCB (Printed Circuit Board) is the brain of your boiler.
It sends messages to every electrical component telling it what to do. This board can cause serious damage if there is even a small leak.
Your Gas Safety Engineer can diagnose the problem and recommend which parts should be replaced. It could cost up to £500 for a damaged PCB to be replaced. This will fix your fault code.
If not it may be worth investing in a new boiler installation instead especially if you boiler is over 10 years old.
How do I fix my Worcester Bosch Boiler with the 227 fault code?
This 227 fault code is usually related to the boiler unit and the gas supply.
It must be legally resolved by a registered Gas Safe Engineer. It is worth checking the status and supply of your mains gas before calling an engineer or checking your Worcester boiler warranty.
- To check if other appliances that are gas-fueled work,
- After adding credit, ensure your pre-paid gas meter is charged.
- Ask your supplier about disruptions that may be occurring in the area.
