Hi all,
I am having a very interesting issue with my BES870. I normally would wake up to make myself a coffee with this machine and everything was fine. I can consistently make a coffee with pressure indicating the sweat spot range.
However, whenever the missus would like a cuppa, i would then proceed to dump the used grounds and restart the coffee making process. This is when i always get the pressure wayyyyyy to high (over extraction).
This is really strange for me and i cant figure out what i did wrong. Note that if i made a cup of coffee in the morning with success, and come back home in the evening for another cup, all would be good. The issue only arises when i am trying to make 2 consecutive cups of coffee.
Now the funny thing is, i have done everything as consistent as the first cup i made, but would consistently fail on the immediate second cup. Things to note:
1) beans are fresh and grind with same coarseness settings (Number 4 settings)
2) amount of beans settings have been left the same between cup 1 and cup 2
3) temper pressure is kept as close to identical as i can (Note this can be subjective, but if the inconsistency in temping pressure is the issue, why is it always the immediate second cup that fails?)
4) i DO NOT reuse the beans from the first cup.
5) after extraction of the first shot, i would dump the used ground beans, take out the portafilter and the basket for a quick rinse, before grounding new coffee beans for the next cup.
Lastly, i did notice that there is a word "lock" just under the grouphead which is suppose to aligned with the portafilter handle when the portafilter is lock against the grouphead. However, if i overturn the handle where it would exceed the alignment against the word lock, i am likely to get an over extraction. I suspect this is because the ground beans within the porta filter is pushed up against the grouphead too much and further compacting the beans within causing pressure to rise.
Now when i make my first and second coffee, i try my best to align the handle against the word "lock"on the grouphead. It seems to not work. On the second cup, i might want to try easing it about just 1cm off from the word "lock" and seem to have minor success (not consistent).
Can anyone shed some light on my issue? Thanks so much in advance.
Cheers!
