Hi, i have the above named boiler and its starting to give me some grief,well noise actually.
The boiler works i get hot water and the radiators are fine.
But when it cuts in and out it makes a terrible noise,like a screeching noise.
Its only recently started happening,it is not the fan because i know what that sounds like because its gone wrong before on me.
I live in a block of four flats we all have our own tank in the loft fed by a main one.
Can anyone help or suggest anything? ty
