Posted Sat Nov 30, 2013, 11:49pm Subject: Steam valve on Duetto 3 "creaky"
When I open or close the steam knob on my Duetto 3, the valve "creaks". It almost sounds like a spring which is rubbing against something. When I first purchased the machine, turning the valve was quite quiet. Now it's become noisier and a little more difficult to turn.
I'm wondering if this is normal or if there is something I need to lubricate? If I do need to lubricate something, what oil should I use and how do I lubricate it?
Garbage In, Garbage Out, for every step of the process. From Beans to grinder, grounds to machine, coffee to cup.

My Duetto II does the exact same thing since almost new. I found that the end of valve spring ( which is rough) drags at the base as its compressed. I have lubed with 111. And after awhile it comes back. Its been doing it for 2 years. I just live with it until my ocd kicks in overdrive. Then Ill polish the spring ends on a stone.
