Hi. My delonghi 3500 coffee machine is not able to froth milk. There is no water coming out of the hose. All water ending in the tray instead. Pushing hot water button the machine starts with a pumping sound and the water ends in the tray too. All the o-rings look good. Tried to decal the solinoid hose (read somewhere that could be the problem). Still the same. Anybody have a nice solution?
I have a similar unit. One problem I had was a clogged solenoid for the frother. The solenoid is toward the front of my unit, connected to the frother by a hose. As I recall, I applied power to the solenoid and it did nothing. I figured it was clogged with minerals from hard water so I removed the solenoid from the machine, soaked it in vinegar, and tapped it a bunch of times to try loosen things up. Eventually, I could hear it engage when I applied power to it. I reinstalled it and the frother was working again.
Please note that the solenoids and pump inside the machine operate at full line voltage (e.g. 120VAC). Line voltage can hurt or even kill a person so you need to know what you're doing to work with it.
Testimonial: "Hi Rick. Thank you for your answer. Is this the solenoid that was clogged in your machine? http://www.ereplacementparts.com/solenoid-valve-p-695717.html?osCsid=7jhfdinc1dq6loh11amec9j117"
Nope. My unit is the 4500 and the parts diagram is:http://www.ereplacementparts.com/delongh...

Ah, it posts the comment on 'return'. Anyway, in that diagram, page D the part is 93. The replacement is listed as:http://www.ereplacementparts.com/solenoi...
One last thing. I also found a clog in the U-shaped boiler once by noting that neither water nor air would flow through it. Hard water is tough on these machines.
Thanks again Rick. It most be located somewhere near hpthe

Ups... near the nozzle. Time to dig deeper :)
It's been awhile since I had it apart but I think getting the 'skin' off was half the battle. I'm sure I cracked a couple things getting it open but once you can see the guts, you should see the hose come around from the boiler to the solenoid and then to the frother.

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.

First, check to see if it will pump out steam without a ton of water. If it doesn't, don't use it.
Now, skim milk is terrible for it, the bubbles are too dry and
flavorless. Use 2% milk or half-and-half. It should be cold (very
cold). I put mine in the freezer in a steel frothing container for 5-10
minutes before use. Just barely submerge the wand (about .25") and turn
on the pressure. It should sound like tearing paper (not like blowing
bubbles through a straw). Do this until volume increases to around
double (if you have a frothing thermometer, it should be around 100
degrees F). Now submerge the wand farther and tilt the cup to create
swirling (this is called stretching & sweetens the milk). This
should be done until the temperature is around 140-160 degrees F. Done.
If your machine is no good for steam, there's another way: Put milk
into a steel cooking pot (I use a saucier for large groups) and put it
in the freezer. When very cold (ice forming) put on stove. Whisk
briskly while heating up on medium-high. It will create fine foam &
stretch the milk at the same time. The bubbles will start big, but
become finer as time goes by. I test by stocking my finger in &
going until it feels nearly scalding & remove from heat. Just use a
ladle for he milk & a spoon for the foam.

can also - press menu untill temp comes up - set to high.
(only low med and high)
SOURCE: There is no milk coming out of the frothing part
If no milk comes out of frother, check the o-ring on the upper "plug" where the milk jar connects to the machine. There are two connectors; only the bottom one corresponds to the steam output while the upper one is a plug. Mine had a worn out o-ring on the plug, and this keeps the machine from frothing 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!).
