title_body: Espresso, pour starts dripping halfway?
upvoted_answer: There may be some advice on this. My first will be to check the pressure as you can do this with your pretty machine. Please check if you are around 9 bars when pulling the shot.
  
  One reason of delay is, it takes a while for the water to wet the grounds. So, it is normal to wait for a few seconds to see the first drops. However; if it is more than a few seconds, the most possible problems I can think of are:
  
  
  The pressure is not enough
  You have tamped so forcefully
  The grind is too fine
