Less impressed with the nut behind the wheel or the grinder? *:-? ;D
Mix heat, humidity, and underdosing with coffee too old or too finely ground and you can easily clog a grinder.
Best bet is remove the top burr and clean it.
Flick the knobs off the worm drive with a thin flat blade screwdriver. Work from the centre of the drive toward the lower internal edges of the knobs. Use an allen key and remove the entire assembly and then unscrew the top burr and clean things. Brush + vacuum, but no forced air. Its best to keep grounds away from the threads and I usually lubricate the thread of the top burr with a little food safe lube to assist in reassembly.
Reassemble and screw the burrs down until they contact and then come back 1/3 turn and then its calibrate time again- using grind on demand, NOT timed grind.
Keep in mind that you shouldnt ever play with timed grind until you have the grind right and also dont go finer without pulsing the grinder or you can clog and/or sieze it.
