Hello,
With my old Delonghi ECAM 23 450S, some of the water ends up directly in the drip tray instead of in the coffee, as far as I've read there are two causes, the upper solenoid valve or the upper brew group, can you narrow it down further or does it only help to replace at good luck?
I opened the coffee machine and to test the upper hose marked red in the picture times pulled off and put a measuring cup under it. Already when switching on comes out there ne small amount of water, that seems normal, but what bothers me are the 40-50ml that come out during the brewing process there.
