My Bianca is 5 Month old, getting water from DVA water softner. Everything working properly but one month ago I stated to hear some noises. Sometimes it’s “ticks” Sometimes it’s sounds like water with air or starve pipe.
From my hearing, it’s sounds from the grouphead, it’s always appears in the first brew ,when the machine is after IDLE. Less After, coming and go.
One interesting thing, is that if I’ll start with the pedal on half way, no noise.
I tried with plumbing and with water tank.
I Attached some files, hope someone will figure it up.
