Question about Rancilio (RAROCKYND) Grinder

Rocky grind settings

I just got a rocky second hand with my new silvia. The grinder is great but im not noticing any difference between any of the settings. Went to make some course for presspot and it looked the same as the grind setting for the espresso. Also the little button on top seems loose, could that be the problem? Is it possible to fix this myself?

The little button on the top locks the grind to the set position. If it is falling down and not engaging the collar, the collar will turn and rest the grind to a very fine setting. If this is happening, you have to clear the hole that it sits in. Easier said than done, but not too difficult.
First, remove the bean hopper. Then carefully unscrew the collar all the way out. You will see the grinding burrs here. This is where you can change them if needed - not our problem now. Lift out the button out, and there should be a spring too. The hole frequently gets packed with coffee grounds. You can use a drill bit - by hand - or a philips screwdriver (takes longer) to take the grounds out of the hole. Replace spring and button, working it up and down to ensure proper movement. Clean the threads of the collar with a brush and carefully screw back together. This step is important! You could ruin the grinder if the collar is not straight!
When you get it screwed in most of the way, start the grinder. Slowly screw it in until you hear a "zing" when the burrs touch. Stop and back off another 1/4 turn. This should be the espresso setting and the button should come up and lock the collar in place.

Good luck!

Our Silvia, almost 8 years old, is putting out shots too fast (10 to 15 seconds), even though we've been dialing down the grind on Rocky more fine, putting more coffee in, and tamping harder. We...


Try to redo what you have been doing, but set it to the extremes to see if everything is functioning. If you set the grind say to 4, it should come out very slow or maybe not at all.

Coffee exits portafilter too quickly. Rocky grinder with burrs set as close as possible. Grinders and rubber recently replaced.


Sounds like your group handle needs a new basket (the piece with all the small holes in it). Presuming that grind is set correctly and that coffee is being tamped enough? Sometimes as the basket gets older, the holes can get larger and coffee doesn't have enough time to infuse with the coffee before exiting.

Have you tried to hoover up the grinds from time to time, from the grinder blades. The coffee beans and ground can gather under the blades from over time. It should not be a problem though.
For better crema you may want to replace the blades.You should replace every 3-6 years. Rancilio Rocky Grinder Flat blades

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.

Silvia pressure issue


The Silvia comes equipped with a "pressurestat" that may have gone out of adjustment. Do a google search on that and you will find numerous pictoral guides on how to do this. The owner's manual that came with the machine (they have electronic versions at espressotec.com, among other places) will also give you basic instructions. Good luck!

Rancilio rocky grinder setting


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.

I just got a used Rocky grinder. It works great but I read about


the grinding itself makes noise. if you have noise in empty spinning than you should consider changing bearings( 2 of them) in the motor.
during opening grinder pay attention to lower holder of burr which spins together with axis, try to be gentle with that part.

Rocky Calibration


  1. replacement of burrs after 500 kg grinded coffe
  2. if upper burr holder and the body of grinder does not hold stabile, teflon aplying does not help too much, it is only temporary solution. new upper bur holder would do better.
  3. before inserting upper burr holder you should check if lower burr is rotating syncronized, you should take a bit chalk and sof touch while burr rotates. after that you stop grinder and look do you have circle with same thiknes, that would give you idea where is the problem, if it is in lower burr.
