Steamer is not getting hot enough.

Here are some possible reasons why the milk steamer flow is diminished and steam is not coming out of the bottom of the machine:

Clogged steam wand: The steam wand might be clogged with milk residue, which can restrict the flow of steam. Try cleaning the steam wand with a damp cloth or a pipe cleaner.

Faulty steam valve: The steam valve might be faulty or damaged, which can cause a decrease in steam pressure. In this case, you may need to replace the valve.

Blocked milk frother: The milk frother might be blocked with milk residue, which can prevent the milk from frothing properly. Try cleaning the milk frother with a damp cloth or a pipe cleaner.

Faulty milk frother: The milk frother might be faulty or damaged, which can cause a decrease in milk flow and prevent proper frothing. In this case, you may need to replace the milk frother.

If none of these solutions work, it's best to contact DeLonghi's customer service for further assistance

I'm guessing this is a table top machine. If so then I take your meaning of "Blowing Off" as in turning off or running out of steam. The table top steamers usually found on home units do not have the capacity to froth large mugs like a "Venti" 20 oz cups. You will have to wait for the boiler to re-heat. It's best to heat a smaller cup of cold milk, pour the milk into the venti and make a 2nd batch again with cold milk. (It's hard to re-froth hot milk).
* check your steam wand tip if it's plugged with old milk. Soaking the wand in warm water overnite will help soften the milk which can be blow out when you make steam again. If you make a lot of milk drinks, it's a good idea to give the wand a blast of steam, then a good wipe with a damp cloth to keep milk residue off the wand.
* It's also possible your steam heater is starting to clog up. If you find that it gets slower and less steam with time then the steamer will need to be replaced. Check your warranty and call for service.
* Please update question with brand and model if you want more help.

Take off the end bit; it unscrews. Poke a needle through the hole; I find it gets blocked quite regularly. While it's disconnected turn the knob on the right. Steam should come out. If it doesn't there is a blockage inside the machine and you need to get inside it to fix it. But the only blockage I've had is in the end bit.

My XP5240 also started blowing the steamer wand off after about 3 months of use, despite fiollowing the Krups cleaning instructions. Here's what I did to fix it.

A: The Problems.
The wand has three holes in the coffee end (center, and on each side). The center hole gets blocked with milk residue. This causes a pressure build up in the wand assembly, and eventually this is enough pressure to overcome the three gripping clips that hold the wand to the nozzle tube. I suspect this was an intentional design for safety. It's unfortunate that it also sprays the user with milk when it lets go.

The second problem is that removing the wand requires that the outer clip retainer ring to be slid down to release the clips. Many users don't realize this and try to pry or twist the wand off. This breaks the clips.

B: The Solution
The wand has to be regularly and throughly cleaned. Just soaking it is not enough. Do it this way:

1. Slide the clip retainer ring down, and then hold the steam tube and gently move the wand straight down. DO NOT try to twist the wand to one side, or you WILL break the clips.

2. Holding the ring, unscrew the coffee nozzle end. The wand separates into three parts: Outer tube, inner steam tube and decorative cylinder.

3. Use a needle or very fine wire (approx 0.4mm) to clear the three holes in the coffee end nozzle.

4. You now need to clear the metal wand tube of milk residue. I found that a 7/64" drill bit was perfect to do this, as it fits snugly in the tube. The amount of gunk removed was surprising.

5. Blow the tube clear from both ends. If it's clean, you will be able to see light through all three holes. If not, go back to step #3.

6. Make sure that there is no milk residue on the steamer tube nozzle where the wand clips on. Milk contains fat, and this is an unwanted lubricant.

After cleaning, my steamer works properly for several days. I also located a 21mm ID O-ring at the local hardware store to hook over the clips. This provides a bit more clip gripping pressure, but will still allow the wand to come off should steam pressure gets excessive.

First check the nozzle at the end of the steam wand, if you have hot water for coffee then you should have something coming out of the steam wand. If the wand is not blocked and the pressure is low then the thermostat might need to be replaced.

For the grouphead check the basket there might be a slight bump around the edge that is preventing it from making a good seal when it contacts the gasket in the head. If the Double works fine then the gasket is not the problem.
For the steam wand try flushing wand for 3 seconds just before steaming, if that does not help with the watery milk, then the boiler is not getting hot enough to produce steam.

I worked at StarBucks, what we did was put water into a contaner and steam the water, a lot of the time why the steamer doesn'..t work as well is because it is clogged. Another way to do it is to just run your steamer, also go to a coffee store and buy expresso machine cleaner. It could just need a good cleaning.

I've just taken delivery of an S9 and my lattes were lukewarm too. What you have to do is move the dial on the steamer to the 3 o clock position. See http://cdn2.libsyn.com/coffeegeek/jura_frothxpress.mov?nvb=20081110133816&nva=20081111133816&t=018ee7ad85c33f422c6a5 . Latte I just made was piping hot. If that doesn't fix it, try the Products settings. If still lukewarm I think you should contact your dealer, maybe you have a duff machine.

he trick to this is making sure you have steam comming out of the wand and not water. To do this, make sure you get the steam started before you begin. To get a light foam that will not deflate, hold the wand just under the surface of the milk. You should hear a steady, high pitched noise and you should not hear the splatter of bubbles popping on the surface. Popping noises mean that the wand is too high in the milk and your froth will not hold up. A low pitched noise from the cup means that the wand is too far down in the milk. This will heat your milk (for hot chocolate), but will not give you a good foam. Good luck!

Something is stuck inside the wand. Get a small pice of wire or small paperclip and inset and try to clear the blockage
