Quick question...

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?

Thanks.

Food grade lube is all I would use.  I show the tube Plindy used on the link below.

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.
