Hi,
So eventually it started to cough up the coffee. It wasn't clogged, but my conclusion is that the zero point setup is elusive and confusing (maybe in my machine or maybe it's because it's new, I have no clue). But what I did, is turning the worm back and forth to make about 3 numbers to the coarse and back to fine and back again until the coffee started to come out. I guess Dan was right about the disks being too far apart but I can't explain how I reached the zero point at the beginning and backed up about one number to have the disks so far apart. That is why I think the clicking I was hearing maybe weren't indicating the zero point but unfitted disks, or god knows what..
In experimenting with it for a short time I think I came to my own setup procedure avoiding the zero point all together, because as I mentioned, i found it elusive and confusing and probably not a true science either. The following require a bit patience and about a 200-300 grams of Espresso beans to get the best results on YOUR Espresso machine. So maybe you should buy a cheaper bag of coffee for this experiment...
1. I took away the hand guard from the doser to allow a free access to the chute for repetitive cleaning (to make the new grind free from grains of the previous grind for accuracy)
2. I closed the hatch form the hopper to the burr and poured some coffee beans and turned on the machine
3. Opened the hatch to let few beans in and watched the coffee grind that comes out to the doser.
4. Turned off the machine, put a piece of aluminum foil under the doser opening and pulled the lever to get the coffee out and on the foil. Observed its coarseness. If it looked still grainy then I'd set the burr on a finer number (turning counter clockwise).
6. Cleaned the chute from the remainder of the coffee using a soft brush and cleaned the doser by pulling the lever until most of the coffee was out.
7. Turned the machine back on, closed the hatch and poured some more beans.
8. Moved the worm 1 to 2 numbers (as long as there is no harsh clicking noise from the burrs then it's safe), and repeated the process.
9. When the coffee started to get finer, I began to make Espresso cups to observe the flow, crema and taste.
10. I repeated the process until I got the fineness that I wanted and the Espresso was incredibly better.
This whole thing took me about 20 minutes to complete and it may vary from machine to machine and one's taste preferences...
With that said, such a machine may be an overkill for one who makes just a few Espresso cups a day (because of the hassle involved in cleaning the chute to avoid stale coffee - believe it or not the chute stores a shot worth of coffee), but could be a major improvement for one who is entertaining a lot or have a small business... but that is a different discussion.
Thank you.
