On the adjusting knob there are 2 set screws (outside of the center) and an adjustment screw (the one in the middle). First make sure the LARGE screws on the side of the SELECTOR plate are tight. Start with the selector on Turkish, with the grinder OFF loosen the set screws about one full turn each. Leaving the selector on Turkish turn the grinder on and gradually VERY SLOWLY turn the center screw clockwise. Eventually you will hear the burrs inside touching. After they touch back of the center screw about 1/8 of a turn. Tighten the SET SCREWS tight as they may allow the grinder to go out of adjustment if not tight. Test the grind with very little coffee and throw those grounds out. Then grind and brew! If these grinders are adjusted too fine you may have problems with the grinds not falling and may back up.

Simonelli Microbar ii the grinder positions change settings every time make a coffee grinder mooving positions automaticaly


First, I'm not a Simonelli technician. Though I've worked on similar table top machines.
* The grinder on these small machines (compared to commercial units) are usually manually adjusted. They are usually built with a range from very fine Turkish coffee (like talcum powder) to a fairly fine auto drip grind. You should not be able to coarse it up as used in a french press.
* There should be some sort of indexing to indicate at least the direction to rotate the grind adjust, say; fine to coarse, or even Turkish to American, etc. Though it may be a generic + to -.
* There may be a positive 'click' to each setting or possible hold down lock mechanism. But the most common is a spring loaded nub that clicks into place. If yours did click before and not now then you need to take it in for service as you probably lost the part (tiny ball and spring)
* A thought; If your an "Americano" drinker (course grounds will hot water filtered through it to fill a Mug size cup) then it may have happened when adjusting to the larger grind size. The indexer ball and spring is only held down by the height of the grind ring. Exceeding the largest grind will allow the ball and spring to pop out of position which can fall into the burrs and destroy them. It may be possible the ball (steel ball bearing) is still trapped in the burr plates and moves them around. Can't grind steel.
* Still got problems? Check with vendor or MFR for service or replacement. Most machines of this type do not have serviceable parts or adjustments.

Post cleaning the blades are touching


You should call your vendor for service. Especially if this equipment is on loan from them.
*** The following is for information only. Equipment should be serviced by a qualified tech. ****
* Bunn.com has a free download of their manuals.
* Check the parts diagram if you have assembled everything properly. Often people forget the 'button' (looks like a nickel with a dent in it.)
* Perform the following adjustments WITHOUT beans as they will prevent you from hearing to any problems.
* Opening the burrs too wide (turning too far counter clockwise) will have the plate scraping the cover and you get metal flaking along with a teeth chattering/grinding sound. Turn the adjustment several times CLOCK-WISE and try again. If you still get grinding then take everything apart and check for objects in the burr area then reassemble according to the parts diagram. Make sure you have the correct model and diagram.
* Closing the burrs too tight (Clock-wise) will have the burrs touch and lock up together. There is another loud grinding sound but not as bad as hitting the case. Though back it off fast as you will ruin the plates if they over heat.
* Note; Once you get things in range. (No loud metal chatter or grinding sounds. Just a nice hum and whirling sound. The you will need to calibrate the plate. Go ahead and add a few table spoons of beans. Keep it to a very small amount as you will probably end up dumping them (a waste). I use 'expired' or old beans for this.
* Calibration is done by grinding a few beans at a time. You must clear the beans completely before adjusting to the next setting. Keep turning the dial to the fine setting. Keep grinding small doses until you get to the level of grind that matches the finest setting on the dial (usually Turkish grind which is almost a powder.) Adjust this back (Larger) a bit as most people end up burning the beans at this fine a grind. It also takes forever to grind a whole bag, even with only 10 oz of beans. Lock down the adjustment screw once your satisfied with the grind matching the dial.
* Note; If you find the motor trips out often then back off the grinder for a larger (course) grind.
*Finally check with your vendor if your still having problems.

I cannot adjust the grinds its only cming out fine even if I turn the screw in the center


You should call your vendor for service.
*** The following is for information only. Service should be done by a qualified tech.***
* Check bunn.com for a free download of the G3 manual
* If turning the dial does not change the grind size then the inner burr spring is broken, stuck, of missing (it broke into small pieces to fall into someone's coffee grounds). Call vendor for service.
* If turning dial is very loose then the lock screw is loose. check setting then tighten down to lock into place. It's usually a small 1/4" hole on the side of the knob.
* The burr plate may be gummed up and stuck in place. Especially if oily beans or 'flavored' beans were ground in this machine often.
* It's possible the Grinder is WAY out of calibration. It's so far out of adjustment that the only setting is fine when the dial is set on course ground. This grinder was not assemble correctly. Check the parts diagram. Call your vendor for service.

Coffee grinder only grinds to course no matter where grind adjuster is set


From what I've read about this grinder, you should be happy that it worked well as long as it did.

I say chuck it & buy a new one!!

When I press the brew button in lights up, I hear the pump going but no coffee???


Barring a serious mechanical problem, I'd say check water level, make sure you aren't using a turkish grind, and clean the machine by running white vinegar through it. 9 bar machines can't push thought a turkish grind very well. Calcium from tap water can clog the machine.

Whatever the setting is at the grind is always fine. What can I do to re-calibrate the grinder?


Grind Adjustment Tools required: Large blade and medium Phillips head screwdrivers In order to adjust the grind, follow these steps (Refer to figure A): 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. dr_buckhead.png

Ground coffee does not come out


Try this, unplug grinder, vac out all beans, then turn grinder towards fine until you cannot turn the big nut in the center of the burr chamber with your fingers. Now turn adjuster towards coarse until you can barely move the middle nut(you should hear and feel the burs touching) now if you look around the edges of the adjustment ring you will see notches, pick a spot any spot just remember where you started, then turn 14 notches towards coarse, your grind should be almost perfect.

Just bought a used one, seems like the espresso grind is pretty course, is there an adjustment I can make?


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.

Why is the grind from my Breville BCG450XL in the finest position coming out like a drip grind with a fair amount of dust mixed in? I have an old Solis with exactly the same conical burrs which is grinding...


The Breville was designed to be used with Pressurized Portafilters, which most Home Espresso Machines have. These filters use a courser grind, so when it says Espresso on the Breville, it's really closer to Drip. The Turkish setting is barely fine enough for Espresso. There is a limiter on the Breville that prevents the user from going any finer, if you crack it open and remove the limiter, you can go as fine as the Solis. Becareful though, the burs can come so close to each other that they can chip and break.

Love your 'handle'!

I'm thinking that there is something in the burr in the unit. Empty the unit and remove the burr. Usually, this is done with a counterclockwise turn. Note how hard it may be to turn...you'll have to reverse this when you put it together. Now, clean out any coffee debris you find. Then, turn the unit over and tap it on a firm surface covered with newspaper. Reassemble and return to service.
