Hi. I noticed the steam comes out within the grouphead when pulling the shot. It happens recently. Regularly did the cleaning with cafetto and backflush.
It does affect the shot quality. I figure out that if i keep the water put from the grouphead for around a minute, the steam can goes out. But after awhile(few mins) the steam will come out again.
Any tech guys who tackled this issue before?
Ive contacted a technician, but they seems refering it to water filter problem which I dont think related. Need some insights and advice. Thankyou
