Worcester Boiler 227 Fault Code: Causes & How to Fix It

Last Updated on January 28, 2025

If you own a Worcester Bosch boiler and have encountered the 227 fault code, it’s essential to understand what it means, why it happens, and how to resolve it effectively. 

This guide provides an in-depth overview of the Worcester Bosch boiler’s EA 227 fault code, helping you diagnose and address the issue to restore your boiler’s functionality.

What Does the Worcester Bosch 227 Fault Code Mean?

The Worcester 227 fault code specifically indicates an issue with flame detection. In simpler terms, your boiler is unable to confirm that the flame required for operation has been established. This typically results in your boiler shutting down as a safety precaution.

It’s a common issue in many Worcester Bosch boilers and is also referred to as the Worcester Error EA 227 or simply the EA 227 fault code.

Common Causes of the Worcester 227 Fault Code

Several factors can trigger the 227 error code. Let’s explore the most common culprits:

1. Gas Supply Issues

• Insufficient gas supply or a blockage can prevent the boiler from igniting properly.
• Check if other gas appliances in your home are working to confirm whether the issue is isolated to the boiler or affects your entire gas supply.

2. Flame Sensing Electrode Problems

• The flame sensing electrode is responsible for detecting the flame. A dirty, damaged, or faulty electrode can fail to recognise the flame, resulting in the Worcester Bosch boiler’s EA 227 fault code.

3. Blocked Condensate Pipe

• A frozen or blocked condensate pipe can lead to ignition failures. This is particularly common during cold weather.

4. Faulty Gas Valve

• The gas valve controls the flow of gas to the boiler. If it’s stuck or malfunctioning, it can lead to the Worcester error EA 227.

5. Air Supply Issues

• An obstruction in the flue or a problem with the boiler’s fan can limit airflow, preventing ignition and causing the 227 error code to appear.

How to Fix the EA 227 Fault Code

While some fixes for the EA 227 fault code may require professional assistance, there are a few steps you can take to troubleshoot the issue yourself:

1. Reset Your Boiler

• Start by resetting your Worcester boiler. This can sometimes clear temporary issues. Refer to your user manual for instructions on how to reset your specific model.

2. Inspect the Gas Supply

• Ensure your gas supply is functional. Check other appliances like your gas stove to confirm if they are working correctly.

3. Check for Condensate Pipe Blockages

• If the weather is freezing, inspect the condensate pipe for ice or blockages. Pour warm (not boiling) water over the pipe to thaw it if necessary.

4. Clean or Replace the Flame Sensing Electrode

• If you suspect the flame sensing electrode is dirty or damaged, it may need cleaning or replacement. This task is best handled by a Gas Safe registered engineer.

5. Examine the Flue

• Ensure the flue is clear of any obstructions. Birds’ nests, debris, or other blockages can restrict airflow and cause the Worcester 227 fault.

6. Call a Gas Safe Engineer

• If the above steps don’t resolve the issue, contact a Gas Safe registered engineer. They can inspect and repair components like the gas valve or fan, ensuring your boiler operates safely and efficiently.

Preventing the Worcester Bosch 227 Fault Code

Regular maintenance is key to avoiding boiler issues like the 227 error code. Here are some tips to keep your boiler running smoothly:

1. Annual Servicing: Schedule a professional boiler service annually to identify and fix potential issues before they become serious problems.
2. Condensate Pipe Insulation: During winter, ensure your condensate pipe is properly insulated to prevent freezing.
3. Clean the Flue: Keep the flue free of debris to maintain proper airflow.
4. Monitor Gas Supply: Ensure your gas supply is stable and address any disruptions promptly.
