Dod you close the valve for the steam to escape and is there enough milk in the frother compartment?

You did not state anything about descaling, but every now and then, I also add water and descaler to the milk container and use the "Frothing" program to run through the water and descaling-solution (double-click the Cappuchino button).
I have also noticed that the first cup (and sometimes even the second) will produce less milk, and not as well frothed milk as later cups. My theory is that the machine is warmer when producing later cups.
If possible, you could try to run two-three frothings of plain water through before switching to milk. I realize this is inconvenient, but it could be worth testing this to see if it helps. We luckily have two milk containers and keep one filled with water just for the purpose of heating up (or whatever we do :) the frothing system before serving the first cappuchino.
Good luck!

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.

Try removing the plastic steaming sleeve and just use the stainless pipe. Keep the pipe just below the surface to make the ffroth, then go lower to heat the milk to a max of 165F.

The most possible problem is that the machine have build up scale both in boiler and in pipe system. Your are still in good chance to solve it easily since it operates normal by performing a good descaling of the machine. You can buy a very good product posibly from ebay like the Urnex DEZCAL which is an excelent descaler and if you perform a couple of descling procedures in a period of one week your machine will perfom better and better.
