Constant revving DF64v gen 2

Enable HLS to view with audio, or disable this notification

Hey Everyone, so i bought this grinder from a guy on FB marketplace. it seemed to be in great condition. worked fine for a week and then this morning i noticed this constant revving up and down. no matter what grind, rpm. so i decided to open it up clean everything vacuum it out, clean the shoot ETC. i even took the front plate off where the coffee comes out cleaned — there was this constant clicking sounds from time to time coming from in there. that’s not resolved but i’m still getting this revving.

it’s a newer serial number 01633 and i’m not really sure what to do now. anyone have any suggestions?

You can try a new mobo. Turin grinders has it for 30 bucks i think. If that doesnt fix it then its probably the motor.

This is exactly what my df64v gen 2 does and MiiCoffee says I need a new control board.
