Rancilio grinder does not grind fine enough for espresso
For about 3 years I've been able to grind fine enough for good espresso. All of a sudden, I can't get a fine grind. I've unscrewed the top grinder, cleaned out the machine, rescrewed the top grinder down as tight as possible and the grind is even worse. The two bur grinders don't seem to get close enough to each other to grind fine. The threads are screwing in properly (not cross-threaded). Any ideas?
Re: Rancilio grinder does not grind fine enough for...
After taking the top burr off several times and rescrewing it, I finally was able to exert enough force to get it to turn a couple of extra turns. Evidently there was some oil or coffee gunk (although I could see none) that snagged the bur. Now it appears to work as before.
This is a great, service by the way. Even the process of thinking through the problem so I could post it helped me solve it.

Hello Darla, if the grinder will not run or make a sound, it usually means that the motor isn't getting power. Make sure it plugged in of course but your main switch may have gone bad and needs to be replaced. As far as leaking grinds; you must have a bad seal between the doser and the mill housing. Feel free to give me an email if you need more info or parts.
The Rancilio Rocky coffee grinder is a superb, highly recommended machine, but its doser is pretty useless in the home. First reason: you want to grind coffee instants before you brew or pull your espresso shot; otherwise, the grinds just lose aromatics and flavor. The doser only works for multiple doses, so you're better off just grinding the amount you need each time. If you're buying a Rocky, get the doserless model.
If you have the doser model, like I do, you also find that the vanes which sweep the coffee into your portafilter or cone leave a layer of grounds on the doser floor. If not cleaned out, they turn rancid. There are coffee web sites with fairly complicated instructions on how to modify the vanes to do a clean sweep. Here's the simple way:
Flip up the doser cover, and spin the vanes while pressing your finger lightly on the outer top edge of one vane. The vanes have enough play so the pressure brings one into light contact with the doser floor, sweeping 99% of the grounds into your waiting portafilter.
There could be a piece broken around the chute where it comes out of the grinder and enters the grounds chamber. There is a rectangular opening in the plastic that can get broken causing the grounds to enter the machine.
This model grinder won't do espresso. There is a DIY mod available online that involves disassembling the machine, and recalibrating the burrs to produce a finer grind. I did it on mine, it was definitely better, but it's not going to get you to the coveted 30 second pull for your espresso. Search on Starbucks Barista Grinder Mod. It is a great grinder otherwise, very reliable.
HI There are 2 things that can cause this. Either the burrs are bad and need replacing or you grinder is out of adjustment and you need to turn to a finer grind. If you have taken it apart, you are not adjusted close enough so your burrs can't grind fine enough. Readjust the burrs closer together.
to get starting point you adjust burrs to touch each other. when they touch each other you have finest grinding, after you hear metal voice you turn back 3 dots and grind only for 1 dose. you check it, if it goes to slow, you go one more back and clean gruinder, THAN you grind 1 dose more. 2 or 3 times and you will get perfect grinding.
because it didn't work a wilde the upper burr holder could be jammed, carefully take id off, clean it good and then put it back until you touch lower burr with the upper.
