Mend Vaillant ecomax 828/2 E Boiler Pressure Loss

How can I fix my Vaillant ecomax 828/2 E presure loss?

Have just purchased a flat with a Vaillant ecomax 828/2 E boiler and under floor heating. My problem is that the presure drops over a couple of days and brings up an F25 fault code. The system is about 5 years old. Any advice please.
