DIY fix possible
Locate a radiator in your home with a bleed valve.Use a radiator key to slightly open the valve and release air while catching the escaping water in a cloth or container.Monitor the pressure gauge on the front of the boiler until the needle drops back into the green 'normal' zone (usually between 1.0 and 1.5 bar).Close the radiator bleed valve tightly once the correct pressure is achieved.
