Coffee machine is struggling to pull milk through from the milk container. Can only make black coffee. Please advise thank you

SOURCE: machine will not **** up the milk,just steam comes

remove and clean the O Rings.

I had the same problem, removed the o rings where the milk frother connects to, there is a green, red and black rubber O ring. Remove them and get a toothpick and clean around where they sit. You will notice a hard milk build up like when you get on your teeth. This is what is causing your problem.

........ o rings.........its as if were working on the space shuttle!!

SOURCE: milk container won't fit onto front of machine

We had the same problem & worked out that it's because the actual milk container is too cold & has contracted from being in a cold part of the fridge. We moved the milk container to the door of the fridge ( it's a little warmer than the rest of the fridge) & it slotted in perfectly the next morning!

I purchased a unit second hand for my wife's birthday today. It's only 4 months old, got it home, tested it, same problem... No froth!

I've read all the posts here and all were very helpful troubleshooting guides however they did not solve the issue.

Understanding how the frothing mechanism functions is half the battle in figuring out the solution. It's a simple vacuum type system. No doubt you've read about checking the orings. This is definately the first thing to check however if this is not the reason then consider the following.

The larger of the white tubes that has the red and black oring inserts deep into its port on the tap. Why? It pushes steam past the milk pipe directly into the chrome frothing tube which causes a vacuum essentially drawing milk up it's hose creating the froth. What you can't see without further investigation is that on the underside of the tube centered between the red and black orings is a small hole. This hole is responsible for drawing the milk upwards. If this is blocked, and it probably is then no milk and no froth. Use a really small screwdriver to carefully clean the white tube both from the front and the little hole underneath.

So in conclusion. Any air leak between the red and black orings will prevent the vacuum required to draw milk up the tube and alternatively any blockage of the milk channel will also obviously prevent the flow into the frothing mechanism. Hope this helps.

Maybe youare not pushing the milk-container sufficiently in. Mine has been increasinglyhard to fit. After speaking with DeLonghi service, they suggested lubricatingthe 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 cookingoil, 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 workssmoothly. I was reluctant to try that out before speaking with DeLonghiservice, 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'. Useat your own risk :-)
