I just rectified this problem with my Nespresso Latissima Pro machine. This model has a milk frothing unit that is removable to place in the fridge for later use. We are on our second frothing unit over 6 yrs and clean the milk frother religiously. Here's the key...there are 5 pieces to the frothing head: head unit, foam selection dial, spout elbow, silicone draw tube and frother to machine joint piece. Our problem was found with the frother to machine joint piece, the piece that gets pushed into the machine to seat the frother. This piece has a larger hole on one end and a very small hole on the other, there are two rubber 'o' rings on the body and a horizontal slit in one side. This piece becomes completely clogged with hard water deposit that is not cleaned out with the descaling solution sold by Nespresso. I have soaked this piece (along with all head components) in CLR and used a syringe to flush CLR through all the little pieces. I let them sit for 15 mins, then soak in hot water for 5 mins and flush thoroughly with hot running water. Seems to have fixed not just my frother I am currently using but my old one also.
