Our friend is right. Two holes ( very small holes ) of the screw nob were blocked ! These holes were responsible for drawing the milk upward by vacuum. I used a needle to unblock these two holes . Bingo the problem was solved and now the steam can produce creamy milk

TYPICAL FAILURE OF THIS MACHINE = THERMAL FUSE MALFUNCTION.
WHERE ARE THE THERMAL FUSES: There are 2 thermal fuses under the coffe tray and 1 fuse under the espresso boiler. (YOU WILL HAVE TO REMOVE THE BOTTOM COVER OF THE MACHINE). What this fuse does is regulate the temperature of the heating element so that everything doesn't melt (yep, I tried to bypass the fuse and found out the hard way..testing...testing..). Anyway, replacement for these thermal fuses are sold at RADIO SHACK for about $2.00. (Yep, only $2.00) If you open the bottom cover of the coffee maker and you will see the 2 fuses, they look like resistors. they are covered in a plastic tube to prevent damage. Clip them off I used a small wrench(radio shack) to pry open the small clamps that hold them, replaced them, then reclamped the new fuse back on.
REPLACEMENT FUSES: The thermal fuses have the watts/Amps and temperature stamped on them. There is 1 part that I use and has been working well for over a year ( over a year, yes this machine can last a long time!!).
The part # is Labeled - Raido Shack 270-1321 Thermal Fuse 438°F (226°C) 250VAC 10A (For heating devices like coffee makers and hair dryers). The temperature may vary + - a few degrees° on the label, from what I have seen.

HOW TO TEST THERMAL FUSES: These fuses are not only used for temp control but they also close the curcuit. If the fuse blows then it is open and will not heat. I use my ohmeter (put 1 prong at each end of the fuse) and if it reads open it means that the thermal fuse is bad, it has blown, there is no current running through it. I believe a light meter can check for continuity also and are much cheaper. Test by putting the test leads at each end of the fuse (1 prong at each end).If the light turns on then you are good, getting continuity. If you cannot get no light then it is bad. You can test your light fuse with a simple wire, touch each end and the light should go on, cut the wire in the middle and no light!!easy.
fyi. If your coffee does not get hot enough the fuse may need to be replaced also.
HOW TO READ THE OHMETER.

Know that a reading of OL means "over limit." That means the resistance is off the charts, and you have a break in the circuit. If you got an OL reading for the plug wires, you'd know there was a broken wire that needs replacing. In this case, we got an OL reading because the light switch is in the "OFF" position.

Consider that a low reading, anywhere from 0 to .5, indicates very little to no resistance. This means there's a continuity of current in the circuit. This is the reading you should get Read more: How to Use an Ohmmeter ' eHow.com http://www.ehow.com/how_2282412_use-ohmmeter.html#ixzz0zwXjz6C0

Need to make a finer coffee grind, and use better quality espresso beans, the best comes from Italy, I like Miscela d Oro

In uk delonghi spares by agents of kenwood.co.uk. there is a directory of local agents. before ordering element check thermal fuse attached to the element it may be open circuit.

DeLonghi BCO120T Programmable Espresso Coffee Maker Team De-Brewerz.com says: 1. Your coffee maker PC board/display might get fused or blown off. You just need to replace the PC board. You can claim the warranty if recently purchased through www.De-Brewerz.com. If you are in India then contact us at [email protected]

There are thermal fuses on the bottom. You must remove the bottom cover to see them under the heating tray. If the heating does not work the water will not heat and rise (no drip - nada). I posted some pics on my ebay store.

This is the actual link....just copy and paste it into your address barof your browser...I found it on the WWW.DeLonghiUSA.com site.Look undercustomer care and then parts and accessories. They have your exactmodel...I did a little reading and it looks like a nice unit I may haveto invest in one myself...Love my morning coffee....with myinternational food creamer...Southern Butter Pecan...you should try itI love it and you may also...but I digress....Hope this helps...Goodluck....and thanks for rating my effort....the Fang

You can find it here. All the best! If you need further help, reach me via phone at https://www.6ya.com/expert/elixirjose_00375ea24bd8141b

There are many possible points that the leak can be.

All points of the water supply from water tank to the pressure pump then to boiler and finally to coffee group. All this are connected together with plastic or Teflon pipes with easy fit unions secure with clips

You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.

In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.
