Automatic Cappuccino feature not working on Delonghi Magnifica EAM3500

The machine will not froth milk, and will not produce hot water from the spout for longer than around 30 seconds before needing to reheat. Regular espresso making is fine. Have tried multiple descaling and cleaning of both the machine and the milk jug with no improvement.

SOURCE: I have a Delonghi Magnifica

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.

SOURCE: Delonghi Magnifica Coffee Maker the milk is not

I had the same problem. With my machine a little O ring came off the main unit. It was on the little pipe above the big pipe where you would slide your jug in to. I bought a spare o ring from the hardware store and all is good now.

Your problem is the holes in the cappuccino maker and
steam nozzle are clogged. Clean the holes in the cappuccino maker and the steam nozzle.

IMPORTANT: Before cleaning the holes in the steam nozzle, make sure that there that it is not hot and there is no pressure on the machine.

I'm sending you a free pdf manual download of what I believe to be your machine. If this is not it, give me the model # and I will try to find it.

Good Luck!

SOURCE: EAM3500S will not froth milk ?

Here's what I did... with great success:
If you've cleaned all the milk deposits from around the o rings and you still have a problem then its almost certainly the milk spout (the little pipe that directs foamy milk into your cup)

Detatch the spout and get a 2.5 mm drill bit and use it to clean all the milk deposits out of the part that plugs into the lid. Rinse through with water to clean away all the bits of hard milk.

[If you put water through the spout before and after, you will notice a dramatic difference]

Doing this completely fixed the problem for me (I had about 3 years of milk build up in mine!).

Delonghi perfecta milk not hot enough

Ummn - something in your Q. seems not right. The milk is not heated directly - its only heated by the steam as it passes by (and picks up) by the milk using a venturi effect - same as a spray bottle attached to a garden hose. You say you have froth - but you can only get that if you have steam... (it does not just blow air thru to create bubbles). So froth = steam & steam = heat... so milk must be hot.
Suggest you check manual for the 'heat' settings for your expresso as this may have been changed. While this is adjustable, the milk is not.

Also always heat your cups before using them - the silver cup 'holder' at the top does a reasonable job but boiling water does far better.
Cheers Mike

Delonghi magnifica promblems with water and milk

Frothing jug
For milk frothing issues, soak the milk jug cover in hot water and rinse several times. If it has a froth control that can be removed by sliding in the direction of travel towards the edge whilst jiggling it gently up and down. Clean off the little o-ring with a toothpick, be gentle. The control should easily slide and click back in place when done.

Froth still no good? Examine the milk coupling to ensure the o-rings are in the right spot and are pliable and undamaged. There should be an o-ring (usually green) on the top spigot, a (black) o-ring at the front of the bottom spigot and a (red) oring at the rear. The groove halfway along the spigot should be clear. Now with the toothpick and a hot moist cloth clean all the crud from the milk coupling, especially inside the smaller spigot. Check the tiny hole at the back of the larger spigot is not blocked.

Check the flow from the hot water spout is good. If not, there are internal issues, try descaling. If it is, test the frothing jug, if it is still weak either the jug cover or the milk coupling needs to be replaced. Get them to try a known good test jug at your local coffee service center to find out which, most will be happy to do this at the counter.

Had the same prolem replaced the coupling where the jug clips in. Item 111 - part number 5532123200 coupling. If your not technically experienced then you may need to take it to a service agent. Had to fairly well dismantle machine to complete repair.

Delonghi Magnifica Coffee Maker the milk is not frothing properly - there's lots of steam & very little milk being issued from the spout We clean the milk jug each day, have adjusted the plastic tube...

You did not state anything about descaling, but every now and then, I also add water and descaler to the milk container and use the "Frothing" program to run through the water and descaling-solution (double-click the Cappuchino button).
I have also noticed that the first cup (and sometimes even the second) will produce less milk, and not as well frothed milk as later cups. My theory is that the machine is warmer when producing later cups.
If possible, you could try to run two-three frothings of plain water through before switching to milk. I realize this is inconvenient, but it could be worth testing this to see if it helps. We luckily have two milk containers and keep one filled with water just for the purpose of heating up (or whatever we do :) the frothing system before serving the first cappuchino.
Good luck!
