Say Goodbye to F25 Boiler Woes!

Dealing with a boiler fault can be frustrating, but fear not – the F25 error on your Vaillant boiler is actually a common issue with a simple solution. The F25 error code typically indicates a problem with the flow temperature sensor, which is responsible for regulating the temperature of the water in your system. To fix this issue, you may need to reset your boiler by turning it off and on again. This simple step can often clear the error code and restore your boiler to its normal operation.

If resetting your boiler doesn’t solve the problem, you may need to check the flow temperature sensor for any signs of damage or blockages. Inspect the sensor carefully and remove any debris that may be obstructing its operation. In some cases, the sensor may need to be replaced to fully resolve the F25 error. Don’t worry – replacing the sensor is a straightforward task that can be easily done by a qualified professional. Once the faulty sensor is replaced, your boiler should be back to its efficient, reliable self in no time.

Simply follow the manufacturer’s instructions to safely increase the water pressure and see if this resolves the F25 error.
