It might be not set correctly as it’s just an expansion vessel

I use the Pegler Yorkshire spring shock arrestor type, no prob's with them and don't have to worry about pressure checks

No hot water to kitchen tap only or central heating
I agree, just so simple to clean the flow straightener and on four occasions I have found this to be all that was required to “fix the boiler”!!
