I have a Breville dual boiler coffee machine, BES920, which is now a year old - it replaced the same machine which we had for 6 or 7 years so I consider I know what I’m doing and what to expect.
I was always happy with the what the first machine produced - coffee tasted good and the leftovers (for want of a word) would fall out of the portafilter in a nicely formed, relatively dry shape - easy to dispose of. The newer machine makes quite different coffee, (though the taste is OK), very sloppy leftovers which can’t be disposed of in a knock box (goes in all directions) and which doesn’t seem to affected by brand or grind.
I complained to Breville early in the piece - we had numerous phone calls discussing how things should work and the fact that the machine never got anywhere near the required pressure (between 8 and 10 on this machine) on the pressure gauge and the machine was replaced - the replacement isn’t any different.
So I think my questions are quite specific -
- what determines the consistency - dry and formed OR sloppy - of the leftover coffee? I would think the grind would affect this but this doesn’t seem to be so.
- what should the should the pressure ideally reach? The needle always wavers just below the ‘8’.
Any suggestions about what I can try will be welcome.
