Steam does not come out of steam pipe

Here are some possible reasons why the milk steamer flow is diminished and steam is not coming out of the bottom of the machine:

Clogged steam wand: The steam wand might be clogged with milk residue, which can restrict the flow of steam. Try cleaning the steam wand with a damp cloth or a pipe cleaner.

Faulty steam valve: The steam valve might be faulty or damaged, which can cause a decrease in steam pressure. In this case, you may need to replace the valve.

Blocked milk frother: The milk frother might be blocked with milk residue, which can prevent the milk from frothing properly. Try cleaning the milk frother with a damp cloth or a pipe cleaner.

Faulty milk frother: The milk frother might be faulty or damaged, which can cause a decrease in milk flow and prevent proper frothing. In this case, you may need to replace the milk frother.

If none of these solutions work, it's best to contact DeLonghi's customer service for further assistance

descale the heating elements with vinnegar.

If you are getting steam out of the wand I suggest you practice and work ha and to learn how to froth up the milk. The machine does not froth up, it is the operator who does. You basically need to keep the wand just below the milk level and keep moving very slowly up and down always trying to stay below the milk level. If the container is wide you may need to swirl as you moving.

when you remove the cappucinotore, ( the piece that sticks down with the chrome tube and rubber pick up tube) from the door, do you still get no steam? that piece should be removed and cleaned daily. if you dont, I would imagine that it is completely blocked with old milk and would block off the steam.

Try removing the plastic steaming sleeve and just use the stainless pipe. Keep the pipe just below the surface to make the ffroth, then go lower to heat the milk to a max of 165F.

Our aeroccino worked fine for 2 years and suddenly it didn't made foam anymore. We tried the "inverting trick" without much success. We contacted Nespresso and they suggested switching from regular fresh milk (we used 2%) to UHT milk (harder to find in US) and to use it cold and freshly opened. So we tried that and it works.
Hope this solution works for you too

Ensure first that you are using the steam pipe in the correct way to froth the milk.

If it still does not work, that means that the steamer is not generating enough pressure steam.

This happens either because there is not enough heat, or if you release the steam when pressure is not enough.

If you think you are doing everything in the right way, then contact the company and insist for having the machine fixed or replaced.

Remove the black plastic outer sleeve of the Frothing Wand (some models have a metal outer sleeve). If done correctly, the “sleeve” has been removed, but the inner wand with red or black washer, is still connected to the machine.
2) The part of the sleeve assembly that you have removed is comprised of 2 pieces, the frothing sleeve and the center piece. The center piece can be seen if you look into the top of the wand.
3) Using a pencil (eraser end), or similar shaped object, push down on the center piece until an audible “click” is heard. The “click” means that the centerpiece is back into the proper position. When in the proper position, the center piece visibly sticks out the bottom of the sleeve about ¼-inch. It looks like a bird beak.
4) Now put the sleeve back on the machine and your machine should be ready to froth again.

As for the milk island, translaltion from the italian solution using google and drying all the parts works

please relay on your experience realizing that you now have new steam pipe(with different holes in the end of it and different pressure)
you will need to get use to them and get maximum quality of that steam pipe.
my advice:

1. every time hold your hand in the bottom of milk container, so that you will prevent overheating which often gives the result you mentioned.
2. every time you use cold milk.
   

The milk can not be room temperature.  It needs to be cool, does not have to be fridge temperature but can not be warmer than room temperature
