I have a Vario grinder that I have had for several years. Most of the time it does okay. But, more often than I would like, the grind gets "off." My "normal" espresso grind will suddenly be too coarse or my "normal" drip grind will be too fine. I use the grinder daily for both espressor and drip so I am switching the setting between the two everyday. It is more of a problem with the drip grind being too fine. Anyone have any input? Right now I have it calibrated in such a way that I can't calibrate it much coarser or it will not be fine enough for the espresso. The way it is set up now, I am using the coarsest settings to grind drip and it is coming out too fine a lot of the time. I saw something about steel burrs that were available for the Vario that would help with coarse grind, but on the Baratza webiste it says "not for espreso." I paid a lot for this grinder and really don't want to have to get another one to use for coarse grinding.
I was wondering if the "adjuster" could get stuck and not allow the burr to drop down for coarser grind?
