Hey everyone. I have a Delonghi EC155 that's about four months old, and I'm using an unpressurized portafilter (the 607706).

Starting about a week ago, all I ever do is choke it. With a Capresso Infinity, I'd gotten used to tamping hard to compensate for the note-quite-espresso-sized grounds. I have a scale now, and I practice 30 pounds, and it still chokes. Even this morning, I don't think there's any way I could have put more than 20lbs of tamp on it, and it took almost a minute for an ounce and a half.

  • My grinder setting hasn't changed, though I guess smacking it to get the grounds out one of these mornings could have adjusted the burr alignment.
  • I recently experimented with home roasting, making about five double shots. I used those beans between 12 and 36 hours after roasting them.
  • I gave the machine its first cleaning with a pack of Dezcal two weeks ago, a little in the afternoon and the rest the next morning. I didn't see anything come out.
  • I've also taken off the brewhead plate twice since then, and it's not clogged.

I know it's not the greatest machine, but any insight would be appreciated!

Depending on the Descal you may have damaged the internals of the machine.  the EC155 is more or a disposable machine. They aren't really made to last a long time.  If your using hard water you may have a piece of scale clogging the copper pipe leading to the brew head.  I would try to take it apart.  Not hard I broke mine own a few times.   If you run into any issues PM me.

Is there any way I'd know if that's the case? I guess I'm not really sure what to look for once I have it open. I can see it now: I'd end up taking the entire thing apart (not having seen anything conclusive), and then not be able to put it back together.
