All appears normal except when the portafilla arm is attached
Hi,
I have the aforementioned Starbucks Barista expresso machine which is about 10 years old. No trouble so far except the portafilla arm replaced recently. My machine has developed another problem where all appears normal, ie temperature ok, and water comes out at what appears pressurised when I does ale the machine without he portafilla, and pump sounds normal, however when I then re attach the portafilla the pump then slows down and doesn't seem able to force the water through the coffee a and portafilla...please help, I'm suffering from caffeine withdrawal ! Haha
If it is the pump does that need replacing and where would I get one, or could it just need cleaning properly of lime scale?
Many thanks
Paul.
