What does the Worcester Bosch EA fault code mean?
The EA fault code indicates that the boiler has failed to detect a flame, which can be due to a lack of gas supply or an ignition issue. This fault prevents the boiler from operating safely and efficiently.
Common Causes
- No gas supply: This can occur if there is an issue with the gas line, such as a blockage or a shut-off valve being closed.
- Ignition failure: This may be caused by a faulty ignition electrode or a problem with the boiler’s control board.
Can I fix it myself? (DIY)
If you suspect a gas supply issue, first check that the gas valve is open and that there are no visible leaks. However, if the problem relates to ignition or internal components, it is essential to contact a Gas Safe Engineer for repairs, as working with gas appliances can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The cost to repair an EA fault can vary significantly based on the underlying issue. For a gas supply issue, you might expect to pay around £80-£150 for a service call and potential adjustments. If the ignition electrode needs replacement, the cost could range from £120-£200 for the part plus £80-£120 for labor, bringing the total to approximately £200-£320.
