Milk container won't fit onto front of machine

This normally happens because the milk supply tube is blocked with congealed, solidified milk. You will need to remove the tube and clean it manually.

When you do cleaning, make sure you use a specialty milk line enzyme cleaner like Rinza.

CHECK GIRDER MAY BE YOU NEED TO JUST TAKE IT APART AND CLEAN MAY BE YOU HAVE TO CHANGE

Add a little Petrol-Gel Food Grade Sanitary Lubricant to the two O-Rings on the machine were the milk container connects. If you do not have that available, wet your fingers with water and rub on O-Rings prior to inserting milk container. O-Rings dry out and go bad, they need lubricant. You can get Petrol-Gel at a restaurant wholesaler or Amazon.

OK, I can answer this one... the same thing happened to me. It would not recognize the water spout. No beep when inserted, but it would beep if you inserted the milk container. Looking into the receptacle, I saw that the switch for the milk container is offset to the right, and the switch for the water spout is offset to the left. All I had to do was carefully bend the lower tang on the water spout that activates the switch to the left a little bit. It looked perfectly straight, but was just offset to the right enough to miss the switch.

Hope this helps someone.

Me too. Mine has been increasingly hard to fit. After speaking with DeLonghi service, they suggested lubricating the o-rings on the nozzles on the machine. I asked if cooking oil would be ok, to which they agreed. To I took a cottonstick and dipped it in ordinary cooking oil, and swept it over the inside of the two nozzles on the milk-container, since the o-rings on the machine itself were hard to get to. Now it works smoothly. I was reluctant to try that out before speaking with DeLonghi service, since they are so set on only using original stuff for the machine, and I did not think a machine this expensive would need this type of 'help'. Use at your own risk :-)

Maybe youare not pushing the milk-container sufficiently in. Mine has been increasinglyhard to fit.

We had a similar problem and it required a replacement coupling block. Part No-111 on the Delonghi part breakdown pdf

I had same problem with DeLonghi PrimaDonna. Three hours with the mentioned fan and the switch started working again.
Thank you so much.

There are 'o' rings on the pipes (on machine - not milk container) where the milk container fits into. replace or clean them - should work like new.

I fixed this problem on my Magnifica by gently scraping the scale away from the inside of the coupling (clearing the hole of scale and debris)
