Troubleshooting the Dreaded F25 Boiler Fault

The F25 boiler fault is a common issue that many homeowners face, but with the right troubleshooting steps, you can quickly get your boiler back in working order. One of the first things to check when encountering this fault is the water pressure. Low water pressure is often the culprit behind the F25 error code, so make sure to check the pressure gauge on your boiler and adjust it accordingly. If the pressure is too low, you can easily top it up using the filling loop on your boiler.

Another common cause of the F25 fault is a blockage in the system, which can prevent the boiler from functioning properly. To address this issue, try bleeding your radiators to release any trapped air that may be causing a blockage. Additionally, check the boiler’s condensate pipe for any obstructions that may be hindering proper drainage. By clearing any blockages in the system, you can help resolve the F25 fault and restore your boiler to its optimal performance.

If you’ve tried adjusting the water pressure and clearing any blockages in the system but are still encountering the F25 fault, it may be time to check the boiler’s pump. A faulty pump can cause the boiler to overheat, triggering the F25 error code. In this case, you may need to have a professional inspect and potentially replace the pump to resolve the issue. By addressing the root cause of the problem, you can say goodbye to your F25 boiler fault woes and enjoy a warm and comfortable home once again.


Don’t let the F25 boiler fault get the best of you – with the right troubleshooting steps and easy fixes, you can quickly resolve the issue and get your boiler back on track. By addressing common causes such as low water pressure, blockages, and faulty pumps, you can say goodbye to your F25 woes and enjoy a hassle-free heating system.
