Today something weird has happened with my Niche Zero.
I adjusted the grind size to 35 to grind for an Aeropress. I then adjusted the setting back to 7 for an espresso. I adjusted it by turning the dial a short way, running the grinder, turning, running etc until I got to 7.
I tamped and prep’d as usual but the water flowed through the puck at a ridiculous rate. 60g in maybe 15 seconds. Like it was super coarse or there was a huge channel
I wondered if I had screwed up my prep, so I tried again and the same thing happened.
It seems to me that the coarse setting that I changed the grinder to has not ‘reset’ to the finer setting for some reason.
It’s not the beans or the machine. Nothing has changed there and I’ve pulled many many shots at 7 on the Niche with these beans and had no issues at all (usually 18 in, 40 out in 35” ish).
Has anyone experienced this problem? Can anyone please offer any advice?
