Weber Workshops Key grind setting wandering

Grinders are one of the keys to exceptional espresso. Discuss them here.

On my dialed in key, i weighed another shot and it flowed as a gusher. Thinking i had screwed up my prep, i weighed another shot and same thing,.. I had to reset the calibration, after which everything was fine. This was the second time that happened over the last 3 weeks.

Is there some aspect of the burrs that can be compromised/moved if the unit freezes/siezes? Its done that a few times. Just seems kinda wonky... and if there is something that needs tightening, cleaning, adjusting... whatever

looking for anyone's experience.

You may want to try re-tightening the burr release screw on the bottom. I've found if my grind setting wanders, it's because that one screw has become loose.

just closing out this thread...

the burr release screw was in fact loose... i figured that out when i had what i thought were dosing issues, and decided to pop the funnel and actually check the screw... (ya i didn't do that until today, since my 'issues' had appeared to subsided...)

once i tightened the screw... i had to re-zero and re-dial in the grinder... we'll see if what i had been attributing to poor and random dosing issues subsides...

@epicurious, thanx for the original suggestion...

at this point i'm wondering if there is a torque suggestion for that cap screw...

They come with lock washers now, IIRC.
