Hi,
My machine recently make terrible sound that seems from the pump. She is 1 years old, not plumbed and I don’t think is pipes touching.
There is connection between the sound to the pressure (the needle vibrates). The sound comes after long IDLE and disappears after 14-20 sec, and maybe comeback in the next brew.
I checked the water reservoir, the pipe, the valve, everything seems fine with the water supply.
Any ideas?
Thanks.
