I have a two year old Saeco Via Venezia that I use with a bottomless portafilter. The machine has recently started to struggle pulling shots to the point where I have had to adjust the grind size up. I should point out that I use a Baratza Encore. Thinking it might be a faulty ball valve, I changed it (as well as the spring and gasket). No change. I have also descaled and cleaned with Puro. The reason I suspect the problem is a lack of pressure is that when I start the shot the pump noise is regular for a few seconds and then it changes to almost the sound it makes if it chokes on too fine a grind; at that point if I open the steam valve for a fraction of a second it seems to give the pump a little more power (upon closing the steam valve). Sometimes one or two short burst like that seem to do it and the flow returns.

Thank you for taking the time to read about my issue.
Other important elements:
- I have used this grinder since getting the VV
- I use the same coffee 80% of the time. The issue is the same with my alternate coffee
- I recently adjusted the steam wand grub screw as recommended by Scooter in these forums (fora?)
