Ive just descaled my Rancilio Silva and run through 2 tanks of flushing water and noticed that when I switch off the pour there is a residual flow through this black tube thing. I recognise the electrical component as a Parker solenoid valve and wonder if it is malfunctioning - just cant understand why the black cigar thing exists there is a delay is shut off and why is there excess water .... and why is there a black tube thing if it is just excess run off ... etc etc etc
So I now have about 15 ml of excess water after every pour
any ideas appreciated
thanks
