Mend Ferroli F24 B Relief Valve Central Heating Pressure

Ferroli domicompact F24 B?

My boiler has been losing pressure for some time. Water comes out the pressure relief valve outlet when the central heating is on. Do I need to re-place the low water pressure siwtch or is it the expansion vessel that's faulty?
