The F24 fault code on your Glow Worm boiler indicates that your central heating return temperature has exceeded 90 degrees – a serious issue that needs immediate attention. You'll typically see this error when there's poor circulation in your heating system, often caused by a failing pump, sludge build-up, or trapped air in your radiators. While you can try some simple fixes like checking water pressure and bleeding your radiators, this fault usually signals a bigger underlying problem. For your safety and peace of mind, it's best to have a Gas Safe registered engineer diagnose the exact cause and implement the right solution. Let's explore what might be triggering this error in your system.

What Does The F24 Fault Code On A Glow Worm Boiler Mean?
Your Glow Worm boiler's F24 fault code indicates that the central heating return temperature has exceeded 90 degrees – a serious issue that requires attention.
When you're looking for F24 troubleshooting tips, it's important to understand that this isn't just any random error code.
Think of your boiler's temperature management system as a careful balancing act. Just like you'd feel uncomfortable in a room that's too hot, your boiler knows when things aren't quite right.
This fault code is your boiler's way of saying, "Hey, the water coming back from your radiators is way too hot!"
Unlike other common fault codes that might point to issues with gas supply or water pressure, F24 specifically tells us there's a problem with how your system is handling heat distribution.
What Causes The F24 Fault Code?
When it comes to the F24 fault code, several underlying issues can trigger this temperature-related error.
Let's explore what's really going on inside your boiler when this happens.
Your boiler might be struggling with a failing pump, which is why regular pump maintenance is so important. If you're noticing this fault, there's a good chance you've got sludge build-up in your system – something we see quite often in Kent homes.
Think of sludge removal as giving your heating system a fresh start!
Other common culprits include trapped air in your radiators (those pesky airlocks!), blocked radiators, or even sensor problems that make your boiler think it's running too hot.
Low water pressure can also trick your boiler into working harder than it should, leading to overheating issues.
How Do You Fix The F24 Error Code On A Glow Worm Boiler?
Several straightforward fixes can resolve the F24 error code on your Glow Worm boiler before calling a professional.
Among our top boiler maintenance tips, you'll want to first check your water pressure and verify it's at the recommended level.
If you're hearing gurgling sounds, try bleeding your radiators to remove trapped air.
Here's a helpful troubleshooting technique: check those isolation valves under your boiler – they're often the sneaky culprits!
If they're closed, simply open them up to get your water flowing again.
You'll also want to inspect your pump, as debris can sometimes block proper circulation.
