Our Ecam 23.450, which is now 12 years old, suddenly has problems with the milk foam preparation. At first it was only occasional and now for a few days almost daily.

The milk foam preparation starts normally, then less foam is dispensed and finally there is no more foam at all and a loud humming noise starts.

The machine was descaled regularly and the upper brewing piston was also descaled every two times. So far, I have only had to replace the upper brewing piston and the seals on the connector in the 12 years.

Where could the fault be?
