If you're seeing the F22 fault code on your Glow Worm boiler, don't panic – it's typically indicating low water pressure in your central heating system. Your pressure gauge should ideally read around 1.5 bar, but when it drops below 1.3 bar, you'll get this error. The most common culprits are leaks, trapped air in pipes, or debris buildup. You can try repressurising your system using the filling loop valves or bleeding your radiators to release trapped air. For persistent issues, though, you'll want a Gas Safe engineer to check for underlying problems. Let's explore some deeper solutions to get your heating back on track.
Key Takeaways
- F22 fault code indicates low water pressure in your Glow Worm boiler, typically showing pressure readings below 1.3 bar.
- The ideal pressure should be between 1 and 1.5 bar; anything lower may cause inefficient heating and hot water problems.
- Repressurising the system using the filling loop is the primary solution for resolving the F22 fault code.
- Common causes include system leaks, trapped air in pipes, or debris blockages affecting normal water pressure.
- If repressurising doesn't solve the issue, contact a Gas Safe engineer to check for underlying problems.
What Does The F22 Fault Code On A Glow Worm Boiler Mean?
When your Glow-worm boiler throws up an F22 fault code, it's telling you there's low water pressure in your central heating system.
As part of regular boiler maintenance, you'll want to keep an eye on your pressure gauge, which should typically show around 1.5 bar for ideal performance.
If you're seeing this fault code, you'll notice your pressure display might be flashing with a reading as low as 0.3 bar. This means your system can't circulate hot water effectively, leaving you with patchy heating or none at all.
Don't worry though – pressure regulation isn't as complicated as it sounds! The good news is that this issue can usually be fixed by simply repressurising your system, and you'll be back to toasty comfort in no time.
What Causes The F22 Fault Code?
Although the F22 fault code might seem alarming, it's typically triggered by low water pressure in your Glow-worm boiler system.
During pressure troubleshooting, you'll want to check for these common issues that can cause the problem to develop.
- Your boiler pressure has dropped below the ideal 1.3 bar level, often due to a leak somewhere in your central heating system.
- You've got air trapped in your pipes, which can disrupt normal water flow and pressure readings.
- Debris, sludge, or limescale has built up in your system, creating blockages that affect pressure.
- Your pressure release valve isn't working correctly, leading to pressure loss.
Regular boiler maintenance can help prevent these issues from occurring.
If you're experiencing persistent F22 faults, it's best to have a professional investigate the underlying cause.
How Do You Fix The F22 Error Code On A Glow Worm Boiler?
Once you've identified the F22 error code on your Glow-worm boiler, you can try several solutions to resolve the issue.
As part of your regular boiler maintenance tips, start by checking your boiler's pressure gauge – it should read between 1 and 1.5 bars for ideal heating system efficiency.
If the pressure's low, you can try repressurising your system using the filling loop valves. Just remember to keep an eye on that pressure gauge while you're doing it!
You might also need to bleed your radiators to release any trapped air.
If these steps don't solve the problem, don't worry – it's time to call in a Gas Safe engineer. They'll check for hidden leaks and might recommend a power flush to keep your system running smoothly.
