Saeco Lirika Coffee
Hello, we have had this Lirika machine in our office for 4 months. Since the beginning, the Lirika has been making 'screeching' noises during the entire brewing process and the coffee is relatively watery. The boss said that was normal ? Cleaning the brew group, greasing, etc. does nothing. Does anyone have similar experience or is this Lirika defective ? Thank you for your input!
