When your Worcester Bosch boiler displays the FA fault code, it's warning you about a potentially serious safety issue – your boiler's detecting a flame when the gas valve should be closed. This could stem from a faulty gas valve, moisture buildup in the electrode assembly, or problems with the ionisation system. While you can try a simple reset by pressing the reset button, this fault code really needs professional attention from a Gas Safe registered engineer to guarantee your safety. They'll diagnose the exact cause and provide a proper fix. Let's explore the specific causes and solutions that'll get your boiler back to peak performance.

What Does The FA Fault Code On A Worcester Bosch Boiler Mean?
The FA fault code on Worcester Bosch boilers is a safety warning that indicates your boiler has detected a flame when it shouldn't.
When you're following essential boiler maintenance tips, this is definitely one error code you'll want to pay attention to, as it could signal a potentially serious issue with your gas valve.
Think of it as your boiler's way of saying, "Hey, something's not quite right here!" The gas valve might be letting gas through even when it's supposed to be completely closed – and that's not something you want to ignore.
As part of proper gas safety precautions, you'll need to get this checked out by a qualified Gas Safe engineer right away.
While it might be tempting to try and fix this yourself, this isn't a DIY job – it requires professional expertise.
What Causes The FA Fault Code?
Safety concerns arise when your Worcester Bosch boiler displays an FA fault code, as it's typically triggered by flame detection after the gas valve should be closed.
This isn't something you'll want to ignore, as it could indicate several underlying issues that need attention.
The most common causes include a faulty gas valve that's not shutting off properly, or moisture buildup in your boiler's electrode assembly.
Sometimes, it's as simple as the ionisation system getting confused and falsely detecting a flame when there shouldn't be one.
In other cases, your boiler's PCB (that's the brain of your boiler) might be playing up and not controlling the gas supply correctly.
Don't worry though – these issues are all fixable with professional help.
