    I had the same problem and was ready to send it in for repairs, but I talked to a great guy at Nespresso who helped me fix it myself. The problem was when I pushed the latte button, it would only froth milk for a second or two and then the espresso would start pouring. It basically refused to make a latte. Here's the things he had me do: 1) Descale immediately. I have an older machine, and descaling once a year does NOT cut it. He told me descaling every 5 months at the bare minimum, if your machine is not having any problems at all. Descaling is usually the main problem for lack of froth. I descaled and it seemed like the machine was working better almost immediately. I also ran 4 - 5 tanks of water through the hot water spout and the main espresso part (but mostly this is because it seems to take this much flushing to get the smell of the descaling solution out). 2) Reset your machine to factory settings. I have a classic Lattissima, so this is how you do it on that machine. Turn the machine on and wait until the drink buttons are steady (espresso and hot water buttons are no longer blinking to warm up). Then press and HOLD the power button until the espresso and hot water buttons BLINK THREE TIMES. Then they'll go back to steady again. You're now back to factory settings. I did notice that I started having the trouble after moving the machine, so I'm not sure which of the above solved the problem. The main thing is it worked and I'm back to yummy lattes!

    Mine stopped pumping milk after 4 years of daily use. I tried all of the above, but no luck. My husband figured out that calcification prevented a switch from closing when the milk container was inserted. once he scraped it off, it worked fine.

    Calcification was residue from milk leaking. The switch is a plunger microswitch that is supposed to be depressed by the plastic blades on the bottom of the milk container lid when inserted. The residue buildup prevented the plunger from being depressed.

After running a descaling cycle we then found that the machine was just not drawing milk at all from the milk receptacle. After trying all sorts of things over several weeks, I then decided to do a 'factory reset' by holding down all four coffee-option buttons for five seconds - and hey presto, it's now working fine! The machine seemed to get some sort of an bug in the electronics / programming.

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: My Nespresso milk frother did not come with

they make one that has the option of frothing milk hot or cold. Blue light is cold. Red light is hot. The red light will always heat the milk. To get to the blue light, you need to hit the button twice.( First will go to red)

Frother only blows steam not frothed milk


The frother is only supposed to blow steam! At least on any of the dozens of machine I have used commercially. You put the frother into your cup of milky coffee and it blow steam and air through the coffee and makes froth. Go to Starbucks, stand near the side counter and watch.

Edited to add yours in not a normal machine, it is a home replica of a pro machine. I suspect it needs cleaning. You can get milk cleaning tablets and liquid for machine that has an enzyme to remove dried or burnt on milk solids.

Here is your manual.

No water coming out or milk coming out of spouts


This is a simple malfunction. Descale the machine one two or three cycles until the flow of water through the hot water pipe is with full jet.
The frothing will also be restored. If it does not, then you may need to clean the Milk stone clogging the frother. Milk stone is like cement and needs care and patience to clean without damaging the frother.
Good luck..

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

My nespresso machine won't froth the milk


Brand of milk definitely matters... Here in Canada I used Sealtest 1% when I first used it and the froth was thick light and luxurious. Then one week picked up Neilsen 1% and found it produced absolutely ZERO froth. Back to Sealtest...back to froth. Milk brand matters....but don't know why.

Hi, the steam from the wand is not frothing the milk like it used to, hardly any froth at all.


If the frother is warming the milk, but is not frothing, then you want to make sure the panarello is clean.

Slide the cover off the frother and check the pin hold on the top edge of the cover. If this hole is blocked the milk will not froth. Rinza is great clean to help prevent these issues. http://www.cerinicoffee.com/rinza_urnex.asp

Also recommend frothing water instead of milk to clean the frother well.

DeLonghi Perfecta ESAM5500 when trying to make a cappucino it wont **** up the milk any ideas thanks


Had this exact problem a few times on a cleaned well maintained milk jug top with an ESAM5500M. Delonghi 'repaired' it by sending a new milk jug frothing top.

It's caused by milk fat deposits, the frother part on the milk jug may look clean but deep inside it's not. I clean mine with pipe cleaners, detergent and hot water and still it wouldn't froth.

The problem re-occurs for me every 6 months or so. You could buy the milk fat remover solution to clean it. Personally I just boil the whole milk jug frother in detergent and the again in descaling solution, that's fixed this problem twice now, although I think it will eventually corrode the 'o' rings on the frother, still cheaper than buying a new frother part each time though.

If it still doesn't work after that, the only other reason for this problem I found mention of was caused by a broken rubber seal where the milk jug fits to the machine. It's most likely to be milk fat deposits inside the frother though.
