Coffee loving electricians?
TL;DR Can bad earth in the mains or even magnetic interference cause grinder static issues?
I’ve got a customer I supplied with a E65S GBW. It kept going out of control - over running, spraying coffee all over the place. Removing the lid, cleaning the clump crusher, vacuuming the grind chamber, resetting, recalibrating blah blah would sort it but only for a few hours.
Understandably she got the hump with that. I replaced the machine, took hers back to my place where it has worked flawlessly for dozens of shots.
Now the replacement machine which I tested before installing is doing the same thing after a couple of hours use.
So is the static not being dissipated through the chassis earth to the mains? Also there’s a router right next to it. Could it be magnetic fields or RFI from that? I’m convinced it’s something to do with the infrastructure or environment there.
