Meaning of the EA227 Worcester Boiler Fault
The EA227 fault on a Worcester boiler indicates a flame signal has been lost during operation. The boiler detects an issue with ignition, combustion, or flame retention, triggering a safety shutdown. The fault prevents the boiler from supplying heating or hot water until the issue is resolved. Worcester Bosch boilers use error codes like EA227 to diagnose problems related to gas supply, ignition, or combustion stability. This specific code often points to an interruption in the gas flow, a problem with the flame sensor, or an issue with the ignition electrode.
Is the EA227 fault specific to Worcester Bosch boilers?
Yes, the EA227 fault code appears on Worcester Bosch boilers. Other boiler brands use different fault codes for similar ignition or combustion issues. Checking the manufacturer’s manual helps confirm the specific meaning of an error code.
Does the EA227 fault mean the boiler is unsafe?
The fault itself does not indicate an immediate danger, but it means the boiler is not working correctly. The safety system shuts the boiler down to prevent gas leaks or incomplete combustion. A Gas Safe engineer should inspect the boiler to identify and fix the issue safely.
Can a power cut cause the EA227 fault?
Yes, a power cut can disrupt the boiler’s operation and cause the flame signal to be lost. After a power outage, resetting the boiler may resolve the fault. If the fault persists, other issues may be affecting the ignition system.
Does resetting the boiler fix the EA227 fault?
Resetting the boiler can clear the fault temporarily if the issue is minor. However, if the underlying problem remains, the fault will return. If multiple resets are needed, a professional inspection is required.
The next section will describe the symptoms of the EA227 fault in more detail.
Symptoms of the EA227 Worcester Boiler Fault
The EA227 fault on a Worcester boiler prevents the system from igniting and producing heat. The most noticeable symptom is a complete loss of heating and hot water. The boiler’s display shows the EA227 error code, often flashing or accompanied by a warning symbol. You may hear the boiler attempting to ignite multiple times before shutting down. In some cases, the boiler makes clicking or sparking sounds, indicating repeated ignition attempts. If the flame briefly ignites before cutting out, the issue likely involves flame detection. A red or amber warning light may appear on some models, signalling a lockout.
How To Recognise The EA227 Worcester Fault on Different Types of Boilers
Worcester Bosch Combi Boilers
On modern Worcester combi boilers, the EA227 fault appears on the digital display with a flashing error code. The boiler may attempt to ignite multiple times before stopping completely. You may notice a loss of both heating and hot water, and the reset button may flash or change colour.
Worcester Bosch System Boilers
Worcester system boilers also display the EA227 fault on their digital screen. The error prevents the boiler from heating the central heating system, but stored hot water in the cylinder may still be available for a short period. The boiler may attempt ignition cycles before shutting down with a warning light.
Older Worcester Boilers Without Digital Displays
On older non-digital Worcester boilers, the EA227 fault does not appear as a code but manifests as a failure to ignite. The boiler may attempt to fire up multiple times before shutting down. The reset light or flame failure light may blink, and there may be a repeated clicking sound from the ignition system.
The next section suggests actions to take in the event of the EA227 Worcester Boiler Fault.
What to Do When Your Worcester Boiler Shows the EA227 Boiler Fault
When your Worcester boiler displays the EA227 fault code, the first step is to reset the system. Locate the reset button on the boiler and hold it for 3–5 seconds. If the boiler restarts successfully, monitor it to ensure the fault does not return. If the fault reappears, check that the gas supply is active by ensuring other gas appliances, like a hob, are working. Low gas pressure, supply issues, or an unpaid bill can interrupt gas flow and trigger the fault.
Check the boiler’s condensate pipe, especially in cold weather, as frozen condensate pipes can cause ignition issues. If the pipe is frozen, thaw it carefully using warm (not boiling) water and reset the boiler. Inspect the external flue for blockages, such as debris or ice, as airflow problems can prevent ignition.
Safety Disclaimer
Only follow troubleshooting steps outlined in the Worcester Bosch instruction manual. Avoid removing the boiler cover or attempting internal repairs. If the EA227 fault persists after basic checks, contact a Gas Safe engineer for a professional inspection. Working on a gas appliance without certification is illegal and unsafe.
How do I reset my Worcester boiler after an EA227 fault?
Press and hold the reset button for 3–5 seconds, then wait for the boiler to attempt ignition. If the fault reappears, further investigation is needed.
Should I turn my boiler off when the EA227 fault appears?
Yes, turn the boiler off before checking the gas supply, condensate pipe, or external flue. If the boiler is leaking or making unusual noises, leave it off and call a Gas Safe engineer.
Where is the reset button on my Worcester boiler?
The reset button is usually located on the front panel, near the display screen. Consult the boiler’s user manual if you cannot find it.
Should I shut off the gas supply if my boiler shows EA227?
If you smell gas, hear hissing sounds, or suspect a leak, turn off the gas supply at the mains and call the gas emergency number immediately. If there are no signs of a leak, leave the gas supply on while troubleshooting.
How can I check if my gas supply is working?
Try using another gas appliance, such as a gas hob or cooker. If the appliance does not work, there may be a supply issue. Contact your gas provider for confirmation.
Can I fix the EA227 fault myself?
You can reset the boiler, check the gas supply, inspect the condensate pipe, and ensure the flue is clear. Any repairs beyond these steps require a Gas Safe engineer.
The next section will describe the costs to repair this fault.
Cost to Repair EA227 Worcester Boiler Fault
The cost to repair the EA227 Worcester boiler fault depends on the cause and required parts.

The next section will describe the major causes of the fault in more detail.
The 6 Major Causes of the EA227 Worcester Boiler Fault
The EA227 fault on a Worcester boiler occurs when the flame signal is lost during operation. This happens due to gas supply issues, ignition failure, flame detection problems, flue or ventilation blockages, condensate pipe freezing, or a faulty gas valve. Identifying the root cause helps ensure a safe and efficient repair.
1. Gas Supply Issues
A disrupted gas supply prevents the boiler from igniting, triggering the EA227 fault. Low gas pressure, supply interruptions, or an unpaid gas bill can cause this problem. If other gas appliances do not work, contact your gas provider to check for supply issues.
2. Ignition Failure
A weak ignition spark stops the flame from forming, leading to a failed start-up. The ignition electrode can become worn or covered in carbon deposits, reducing its effectiveness. If the electrode is faulty, a Gas Safe engineer may need to replace it.
3. Faulty Flame Sensor
The flame sensor detects whether the burner is lit. If it fails to detect a stable flame, the boiler shuts down as a safety measure. Dirt, corrosion, or damage to the sensor can cause false readings, requiring cleaning or replacement.
4. Flue or Ventilation Blockage
A blocked flue restricts airflow, preventing proper combustion. External obstructions, such as leaves, debris, or ice, can cause this issue. Check for visible blockages, but do not attempt internal flue repairs without a professional.
5. Frozen Condensate Pipe
In cold weather, the condensate pipe can freeze, causing a blockage. This stops waste water from draining, leading to ignition problems. Thawing the pipe with warm water and insulating it prevents the fault from recurring.
6. Faulty Gas Valve
The gas valve controls the flow of gas to the burner. If it becomes stuck, misaligned, or fails electrically, the boiler cannot maintain a steady flame. Replacing a faulty gas valve requires professional diagnosis and repair.
The next section will describe how to prevent the EA227 Worcester boiler fault from occurring.
Preventing Future EA227 Worcester Boiler Fault
Regular boiler maintenance helps prevent the EA227 fault and ensures safe operation. An annual service by a Gas Safe engineer checks the ignition system, gas valve, flame sensor, and flue for faults. Cleaning components, checking gas pressure, and testing safety mechanisms reduce the risk of flame loss.
A boiler service contract provides routine maintenance and emergency repairs, preventing costly breakdowns. Insulating the condensate pipe in winter prevents freezing, and keeping the external flue clear ensures proper airflow. Monitoring boiler performance and acting on early warning signs helps prevent unexpected failures.
