I would, it’s difficult to know unless you’re experienced enough to tell that it’s grinding a bit slowly and/or the coffee tastes a bit flat. The burrs can still feel sharp to the touch but not be cutting the beans cleanly.
That's interesting. A lot of beans I've had recently have been tasting a bit flat and I've been trying different grinds, extraction times etc. Might be worth shelling out for new burrs as mine haven't been changed sine I got it!
