Hi,
I had a Siemens machine EQ9 S700 repaired today. There coffee stopped coming out of the spout. At first I thought it was the drain valve. But the problem was the clogged ceramic valve. There the holes in the ceramic discs were closed.
Now to my question:
I have never had a machine with ceramic valve and in this Siemens the first where I have not seen a drainage valve. Does it really not have one and is it not necessary due to the ceramic valve? Why do not all machines need such a geranium ?
Thanks for the technical clarification ????
