Question about Rancilio (RAROCKYND) Grinder

1 Answer

Rocky Calibration My Rocky Doseless isn't grinding fine enough for espresso. I've tried everything. I've even tried the teflon tape modification around the upper burr carrier. Still, nothing. I can only get a 15 second pull on the finest setting. I'm about ready to throw Rocky out the window! I've contemplated buying a new set of burrs, but I'm not sure if that would be the answer to my problem. Just so you know, I am using Starbuck's Sumatra blend right now. I ordered a fresh batch of espresso Forte' from Peet's coffee, which should be here by the end of the week. Also note that I am breaking up the clumps of espresso when distributing the coffee in the portafilter. I also apply a 30 pound tamp and a twist to finish it off. Any help is greatly appreciated!

  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.

How often should you need to clean the bean grinder? We seem to be cleaning it every 3 days which seems excessive


No brand or model? Okay, general reasons why grinders clog up. Most common I've found is worn out burrs. The plates, depends on composition and usage. Metal plates last longer but not forever. If your grinding thousand pounds of beans don't expect it to last. I've seen massive grinders fail within a month. It all depends on two factors; How much and how fine. Large grind size will increase life and fine grinds wear the burrs out very fast. Especially Turkish settings. Fine grinds also generate a lot of heat. This can cook the coffee again and make it change in flavor. Heat also forces the oils in the bean to coat the burrs and make them dull out which causes more heat. Prolong grinding will also burn out motor.
* Worse case senario; Very oily beans ground to espresso fine. This is usually the case with 'local' roasters. Poor quality beans, extreme roasting (pushing the max on toasting limits), and extreme fine grinds for a particular roast. Fine grinding tends to work on dryer beans. Heavy moisture (under roasted or beans not aged enough to outgas and dry out) will gum up any grinder. Let your roaster know what your trying to do. Otherwise go with a name brand and correct bean for the flavor profile your looking for. Don't expect 5 star espresso from a cheap roast.
* Final, most likely worn burrs needs to be changed out. Off chance the motor is burnt out or starter capacitor needs replacement. If it is the motor or cap, then you need to review your grinding methods as grinder motors are usually tough enough to handle the range of grinds listed in the specs. burning the motor is a clear sign of abuse.
* Have your vendor look at the grinder. They will know right away what's wrong.

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.

I took everything apart to give it a good cleaning and now all settings produce a very fine grind. Any thoughts?


I had the same problem with too fine a grind when I took mine completely apart to clean (including the lower burr). The solution I finally came around to was to further tighten the star-shaped screw which holds the lower burr assembly in place. I had originally just tightened it until the lower burr until the lower burr assembly started to turn with the screw, but that wasn't enough. So I held the assembly in place and tightened the screw further and I'm back to my previous grind coarseness/fineness.

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.

My super jolly mazzer grinder is switching off after only a few seconds grinding. used to grind continuously for however long i needed, now i have to turn it on 4-5 times just to get enough for one shot! ...


Most grinders, especially the larger professional models will eventually need to have the grinding wheels (set of 2) changed out. They do wear down. The grinder will struggle as the burrs on the wheel dull out. This increases the time it takes to grind coffee and puts a heavy electrical load. Burnt out switches, tripping breaker, overheating, and burnt coffee grounds on espresso size are all symptoms of a worn burr set.
It's common to find; stones, nails, jewelry, and small loose things found around coffee counters in the grinding wheels or burrs. Have a qualified operator remove all beans and hopper to check and brush out burr set. This should be done every day.
Another cause is very oily beans. Sometimes poorly roasted beans come out extremely oily which will gum up everything from the burrs, Moving parts, and electrical components. Disassembly of entire machines may be necessary.

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.

Rocky has a tumbling (unbalanced) sensation when grinding you can feel and hear. Seems less if you back off grind # to 20 from 8. Been using 8 for a year with no problem before today.


  1. take the bell(bean container) carefully out.
  2. disassemble the upper holder of burr
  3. you will see now the burrs, clean good coffee remains than disassemble the burrs
  4. after disassembling burrs clean good the lower and upper burr holder.
  5. carefully switch on the grinder tan switch off(few seconds) during lower plate is rolling touch with marker the surface of burr holder very softly,

  • if it is ok you will have complete circle
  • if it is deformed you will have incomplete circle( that you must compensate with letter tape )under the burrs you apply the letter tape
  • after each correction you mark the burr with marker to see did you achieved perfect result. once you have lower burr in place you screw bolts in upper bur holder and assemble it back in his place.

The coffee comes out in little logs or clumps. The coffee is weak- no crema.


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.

Water leak when brewing, water seeps into tray from inside the machine


The only thing I can think of is either the red oring on the brew unit or the 2 o-rings on the white plastic valve need to be replaced, or the coffee grind is too fine that the pressure is opening the bypass valve.
