I will warm up the subject.
I have a practically exactly the same problem with the twin model 1200. The espresso machine is 2.5 months old and has stopped practically frothing milk. The coffee maker made about 10 coffees a week. I carried out the descaling process 2x without any results. Frother cleaned after each use. @ markap75 Have you dealt with this problem at home or is it still possible to return the device for warranty?
