We recently had a washer from a lyn weber bean cellar run through our EK! Our shear plate broke and we were lucky enough to have a back up shear plate on hand.
After installing the new shear plate and cleaning everything out, our grind adjustment dial has been acting very strange. Most of the time, the dial is very loose, but will occasionally tighten up when fining up the grind setting. Coarse grinding has not seemed to change at all, but we’re having to adjust our espresso settings quite a bit coarser on our dial than before.
When taking the EK apart to clean, I noticed that the prebreaker and rotating grinding disc were very difficult to remove from the motor shaft. Also, placing the prebreaker and rotating grinding disc back on the motor shaft took more effort than I remember previously. All parts have been cleaned and lubricated.
Any ideas what might be causing our loose dial? Thanks for your help!
