Grinder setting stops at drip. Can't turn further to espresso.
I want to try some different grinding settings. I can't get the hopper to turn further past the drip setting. It simply gets stuck. I have taken apart and cleaned and tried with and without beans in hopper and also with and without power on.

Another suggestion is while the grinder is off, turn it up side down and rotate the bean hopper from coarse to fine a couple of times. This will clean out grounds that have gotten into the threads and it will prevent the bean hopper from not turning to a finer grind. If you start to get a clog in your grinder, open it up to a coarse
grind for a few seconds. The coarser grind will clean out the chute
and then you can turn it down again while it is still grinding.

There are many ways to clean oily residue from your burrs. You can order a grinder cleaning tablet from online stores called Grinds by Urnex. Some people use white rice but if you don't get it all out you will have rice in your coffee. You can take them apart and clean them manually but if you don't reassemble it correctly you will not get a good grind. I think the easiest way is to get some cheap light roasted beans ( doesn't matter if they are old ) but never use shiny beans because shiny beans have lots of oil.
Set the grinder to a very coarse setting, on a Rocky 7 higher that you currently use. You can turn it to a larger # any time but it has to be grinding to turn it to a lower #. Pour a cup of cleaner (beans, or rice) into the bean hopper and turn the grinder on. Grind the whole hopper through the machine. If you use grinds just a couple of #'s higher is all you need. Once you have cleaned the burrs you will need to grind some of you beans to purg the cleaning debris for the burrs and chamber. When you see no more cleaning compound you can turn the hopper back to where it was leaving the motor run. Once you get it back test with your beans.
Tools required: Large blade and medium Phillips head screwdrivers
In order to adjust the grind, follow these steps (Refer to
1. Remove all coffee from the hopper.
2. Set selector knob to the finest setting (Espresso or Turkish)
depending on the model.
3. Loosen both knob retainer screws in selector knob one turn only.
4. While pressing the bag switch, located behind the spout, press the
START button so that the grinder will run during adjustment.
810 model - Press the ON or START button so that the grinder will
run during adjustment.
5. With the grinder still running, turn the adjusting screw in the center
of the selector knob slowly to the right until a slight clicking noise is
heard. Immediately turn the adjusting screw to the left one grind setting. This is the finest grind obtainable.
6. Tighten both of the knob retainer screws. Once the ESPRESSO grind has been set (Turkish for Model 835,
875, 890), the other grind settings will automatically set correctly.
7. Press the STOP or OFF button.
IMPORTANT: Always be sure the grinding burrs are not touching while the machine is running on the
ESPRESSO/TURKISH setting. Otherwise serious damage to the motor may result.
It sounds as though your grind is out of adjustment. The grinder is probably set too fine. I have not worked on a G3 grinder but I would think it is like the Bunn G2. On the front knob you will find 2 small set screws and one larger adjustment screw (in the middle of the knob) 1. Set the selector knob to finest setting (Espresso or Turkish) 2. Loosen the 2 set screws about 2 turns. 3. Activate the start switch (you must activate the "bag switch" behind the chute) 4. With the grinder running, SLOWLY turn the center screw clockwise only until you hear a very slight whirring sound (this is the burrs touching). 5. Then, back off the center screw counter-clockwise about 1/8 of a turn, shut off grinder and re-tighten the set screws. Check the grind in the "drip" setting by running a few beans through... the grounds should be about the consistency of sand. You should get a better flow through the machine with the grind adjusted properly. You may want to check the cleanliness of the hopper in the top... I have seen these dirty enough to impede the falling of the beans to the grinder. Also, whenever you remove (for cleaning) the 2 larger screws that hold on the front "plate", be sure to put them back in evenly... kind of like one would with a wheel on a car- Finger-tight then slightly tighten each on a little at a time (back and forth) until tight. Hope this helps.
I would suspect a log in the outlet shute where it goes into the grinds hopper. Clean it out and then turn the hopper to the coarsest setting to clean it out all together. Coarse grinds are a very good cleaner.
To adjust this grinder turn the adjustment nob to the finest setting (ESPRESSO or TURKISH) Locate 2 small set screws on the adjusting nob. Loosen these screws (do not remove them) about one full turn. Start the grinder and, with it running, VERY SLOWLY and GRADUALLY, turn the CENTER adjustment screw clockwise until you begin to hear the burrs begin to touch (whirring sound). Back off the center screw about 1/16 of a turn, shut of grinder and re-tighten the set screws. Then try the grind on DRIP or there about for brewed coffee.
Your burr is not locked in. You need to remove the beans from the hopper. Remove the hopper. Remove the burr. Turn the grinder upside down over the trash can. Put the burr back in only make sure that the burr is down. Install the bean hopper and when you turn the bean hopper it should move the burr. Then you can adjust your grind. Make sure that the grinder is running is your going to a finer grind or you could break the grinder. You can turn it to a coarse grind any time.
Rotate the bean hopper counter clockwise until it stops. Lift it off. Remove the outer burr with the 2 wings and clean under the burr. Clean the opening going to the chute for ground coffee(inside where the burr was). Install the outer burr. Install the bean hopper. Rotate the bean hopper to the French press grind (coarsest) and operate the grinder. This will clean the burrs and the passages. If it starts to clog, repeat the last part to clean the burrs and passage. It must be grinding to go to a finer setting, but you can go to a coarser setting any time. Another thing. Turn the grinder upside down (empty) and rotate the bean hopper back and forth to clean the threads of the adjusting burr..
This fixes almost all the "beans will not feed or beans will not grind"
problems caused by coffee bean dust packed in the burrs. Oily beans
cause this problem more fequently.
a. Pour all the beans out the top.
b. Open the settings up all the way and see what else can be poured
out. Use your shop vacuum to **** grounds out the spout and backward
out the bean bin.
c. Pour in some instant rice and start grinding. Reduce the grind to
a small setting like six and then open the settings all the way again.
(The grinder will not start at a low setting with the rice in it. If
you let it stop, open the settings to about 16 before trying to
d. Pour out the rice and vacuum out the ground rice.
e. Adjust the grinder to your favorite setting and try a coffee grind.
Grind until most of the rice dust is expelled (any remaining trace of
rice dust will not affect the flavor of the coffee).
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.
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 grinder, THAN you grind 1
dose more. 2 or 3 times and you will get perfect grinding.
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.
