Hi, I recently acquired a second hand classic. I initially gave the group head a clean and it was working fine for the first couple of dozen shots. During the last shot, it seemed to choke up and water stopped pouring through the group head.
Pump seems to be working fine, when I turn on the brew and steam switch and open up the steam valve I get a good steady stream of hot water.
When the brew switch is on no water returns to the resevoir.
Is there a specific area I should focus on first before stripping down the whole thing to give it all a good clean?
Thanks!
