I’ve got a Baratza encore which has served faithfully for ~5 years. Lately I noticed the setting jumps around a bunch as I’m grinding, or at least the apparent position of the hopper is moving several clicks worth of distance. Gave it a take-apart and cleaning and noticed the rubber gasket is starting to get worn/torn at the “slots”. Is that likely to be my issue? Or do I have worse problems? I also noticed that Baratza doesn’t have these in stock now :-/
