Received this as a gift couple days ago, and I started to use it this morning and already noticed issue with water remained trapped in portafilter (coffee remained very saturated and became very hard to clean). I used the same espresso grind coffee that I used on my old Mr. Coffee espressor machine (BVMC-ECM260). After I noticed the issue above, I tried several time to not to tamp coffee too hard, but water still remained trapped in portafilter. Even I let it dripped for minutes, there was still water remained and coffee grinds were so wet, so saturated. I also noticed because of the issue above, I did not really get a full 2 shots, probably just 1.75 shots.
