Worcester Bosch Magnetic Filter Running Water Noise

[Dulbert]

Just had a new Worcester Bosch Greenstar 30Ri fitted with the magnetic filter. When the system is running the boiler is so quiet but there is a sound of trickling water through the filter, loud enough to hear quite clearly and is pretty annoying. I wouldn't of thought trapped air would sound like that, its like one of those garden features where to water overflows a small pond into another one! Cant be right, any ideas?

It’s sometimes is air but half of the problem is it’s flow noise / turbulence around the centre of the magnet it should go away after a week etc try bleeding the air vent on top of it
