Question about Coffee Makers & Espresso Machines
My milk container for my Delonghi espresso maker is not properly connecting, when inserted and as a result causes a very low milk flow when steaming. I have to forcefully hold the container pushing inwards in order for it to get a good flow. I am not sure if anyone else has this problem.

I was told this was a problem with the O rings on the machine (you need to keep these clean or replace them (if necessary) to keep the milk container working properly).
I did this and still had the same problem. Turns out the top on the milk container needed to be replaced. It's $20 from Delonghi but at the time of this writing is out of stock (I have waited three seeks so far and Delonghi is supposed to be escalating my request).
I finally got frustrated with the whole thing and completely disassembled the milk container top (there are a total of 5 screws and you need to remove the froth control slider to get to one of them) and gave everything a good cleaning. Pay attention to the small orifice on the inside of the chrome tube that the milk comes out of. Using a dental gum cleaning brush or similar sized brush and some hot soapy water should get the dried milk residue out. Inside the top is also a rubber piece that the froth regulator inserts into. Reomve this rubber piece and clean thoroughly. Make sure and clean all other areas inside the top with hot soapy water. Make sure to look the top over well as you disassemble to be sure note all component positions for reassembly. Make sure when reassembling that the cleaning button and its spring are reassembled correctly. The small red O ring on the end of the cleaning button's rod should be cleaned well and the small tube into which it inserts should be free of any milk residue. One last item to check is the rubber bushing that rubber milk uptake tube inserts into is clean and making a good seal. Note that this bushing should make a good seal on both sides (the side the rubber uptake insrts into and the side the upper side of the top inserts into. Make sure all parts are reassembled correctly. In general if you clean and rejuvinate all areas that need to make a tight seal you should get good results. I have no experience here but it would be my observation that even with a good thorough cleaning job the results may not last a real long time as it seems that parts in the top show wear after about a year and a half of daily use. In my oppinion the purchase of a new $20 top makes sense, but if you can get one or don't want to wait you can spend the 30 minutes to do the above cleaning. Because of apparent backorder issues at Delonghi this may also be a good idea to buy upfront. Make sure to include the 5 O rings in the order ($1 each) to avoid paying two shipping fees. I have found one of the O rings at Lowe but was unable to find a few of the sizes (smaller than Lowes sells).

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 :-)

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.
