Tip & How-To about Rancilio Rocky Espresso Coffee Grinder - Doser

Rancilio Rocky w/ doser: clean sweep of coffee grounds

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.

Doser on Rancilio has worn (I'm guessing) to the where the "ratchet" mechanism doesn't always move forward but hangs and I have to go in and manually turn the vanes. I tried to take the thing (doser) apart but seemed to be missing something. Has anyone worked on the dosers?

Hi There is a spring that holds tension on the paul (ratchet) underneath that is broken. You need to replace the spring. Remove the plate on the bottom of the doser to see the paul and spring. The spring is flat on most Rocky's.

Have Rancilio Rocky for about 3 months. Noticed grinds around base from time to time. Yesterday picked up machine, saw accumulation. Tapped base, more came out. Took off base, about 2 oz. of grinds inside. Common or is mine defective?

Hi 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.

no, dont worry. Just return the lever by hand. Replace the spring and it will break again. It is a hassle to replace and not having it will not affect the function
