Hi Aenne. This sounds like a blockage.
Milk needs the introduction of air in order to foam/froth milk. Automatic espresso machines usually use a Venturi system which is a basic syphon method of introducing air into the steam milk mixture. This comes in the shape of a small manual valve with a fine hole in it. My recommendation would be to clean or change the complete foaming/frothing system manually. Generally there is a small airvalve/expander baffle with a fine hole that has most likely become blocked. You will need to make sure this is clear and that you can blow through it. Also ensure the foamer head is completely clear and runs some milk cleaning solution through
it. This should solve the issue....
If there is no manual air valve, then maybe the machine uses an automatic milk pump to inject the air which may be failing. This may require a technician to replace. I doubt that this will be the case. I hope this helps.
Testimonial: "Hi, thank you, the air valve is clean, I am regurlarly clean the unit, but as the machine is 10 yrs old it might be the pump as you say."
You are welcome. The only other possibility that I have experienced in the past is poor milk quality. Sometimes milk depending on freshness can have difficulty foaming. If you haven't tried already, change the milk to a brand new fresh low fat and maybe try a new complete foamerhead system. It sounds like the temperature is there, there is just an issue with the introduction of air, so this rules out a steam issue. Hope you get this sorted out.

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.

First off, the best milk for foam is skim milk (0% fat). The higher the fat content, the less foamy your foam will be.
The foam is created by the steam/hot coffee from the lower part being forced through the doohickey and into the milk. That means that if the coffee itself isn't "perfect", the foam won't be "perfect". I've found that using different types of coffee (e.g. different grinds) or filling the coffee bin to different levels results in more or less steam/pressure being passed through, so the foam is better/worse. For example, if I put too much ground coffee in the bin or use too fine a grind, it blocks the water/steam that's going through the coffee, resulting in less coffee and weaker coffee, and also resulting in less foam.

You should decalcify, when you steam the milk some what gets through to the steam and the build up of these minerals causes the issue

My Miele cva4075 is not frothing the milk. Also, how do I clean the cappuccinatore?
