Have you descaled the machien recently? Give the group head a good cleaning and descale. This should help clear up the solenoid valve.
Our Gaggia is about 1 year old. After making the coffee, the coffee holder is extremely moist and still has water in it. Before, it was relatively dry. Also, the ready indicator oftens goes off after it is on. I am wondering if the water is not getting hot enough or the pressure is not strong enough when we are making the coffee. What are we to do?
