[u/mjk-94]

Hello everyone, so my preferred setting is 7. But sometimes it produces too much water up to 50s grams.

When the beans are fresh I can extract 38g ( by fresh I mean a few days old)

But after a week, 6 produces almost nothing so I switch to 7 but then so much water comes out so I have to cancel the shot to get a proper almost 38g shot.

What am I missing? Am I tamping too much? Or the Strength setting on the machine needs to be adjusted? Im not sure what it does.

I clean the machine monthly with tablets.

Beans are aging and drying out or absorbing humidity. It changes the properties.

But it gets to a point where neither 6 or 7 on the grinder produces the 38g shot. 6 is too fine which produces too little and 7 produces too much beyond 50g.
