Espresso Steamer leak repair on Gaggia Classic
The milk steamer leaks when machine is on.
See Item on the right:
It has a tiny washer inside it. I replaced that washer to stop the steamer leaking water and steam at the screw on the join at the washer in the image.
What else could be causing the leak?
I note one part of this Steamer is brass the other chromed material... heating and expanding at different rates?
