Soooo....finally got around to getting the machine back to get fixed. Turns out they replaced the Grind Stone and all working good again and enjoying my coffees!
18.5gr in and got 28gr out in 30 seconds using the default 2 cup setting.
I then went manual with 17.5gr and let it run to 35gr out and it did it in 25 seconds.
Both times the pressure was up towards maximum but this is just a case of playing with things but more importantly, it confirms my inbuilt grinder is the problem so will take it back to the repair place and see if they can fix it.
I use the express Bes870 and find that adjusting the top burr down by one unit at a time and raising the inbuilt adjustment to the maximum and then decreasing as testing works for me. The instructions specifically say to only adjust the top burr down by one unit at a time. At "burr to 1 and grind to 1" I suspect there may be misalignment.
Once the "sweet spot" is found small inbuilt machine adjustment is required for different beans or aging of the beans but I have never had to adjust the top burr again.
Ok...so got the machine for the Wife and ran with Dual-Wall 2 cup basket. 18.5gr/Burr on 3/Grind on 1 and Double shot. Works ok but sometimes water does not make it through to the cup about 10% of the time and have to make a new cup. Manageable but the Wife likes the coffee.
I seem to get 10-15 seconds no matter how much I reduce Burr/Grind and finally dropped Burr to 1 and Grind to 1 and I got 36gr in 25 seconds. Coffee seems reasonable at that point but little room for experimenting as it is the lowest setting.
Is this me? The Bean? Surely that can't be normal?
Appreciate any advice....NichoUnited.
