"8. ADJUSTING THE GRINDER
• Open the lid of the bean container.
• While the grinder is running turn the grind selector switch to
the desired position (Fig. 6).
-The smaller the dots, the finer the grind.
-The bigger the dots, the coarser the grind.
The grinding grade can only be adjusted while
the grinder is actually grinding."
Removal Step-1: Remove beans that are in the bean hopper without spilling them inside. (Use Vacuum). Step-2: Remove the beans container by removing 3 phillips head screws. Remove the rubber gasket from below the hopper. At this stage the upper burr will be visible. Step-3: Rotate counter-clockwise the outer ring of the grinder assembly (the ring has gears half way around), until the red mark is at the 9 o’clock position, looking at it from the front of the machine. Step-4: Lift the upper burr by using the fins that are on top. Press lightly on the doser adjustment gear, to clear it from the dose adjustment gear. Cleaning- At this stage, the grinding chamber will be exposed. Clean out any crushed coffee in the grinder chamber and the burrs. Use Vacuum and cleaning brush. To Re-Assemble Step-1: With the red mark on the outer ring still at the 9 o’clock position, replace the upper burr back into the grinder. Make sure that the red line (on the upper burr) is at the 3 o’clock position. This position will align the other tabs as well. During re-installation, press slightly on the doser adjustment gear so the upper burr will clear it as it is placed back in. Step-2: With the Upper burr in place, rotate the outer ring clockwise until it stops. The two red marks should be aligned at the 3 o’clock position underneath the doser adjustment gear. Step-3: Replace the soft rubber gasket back on the upper burr. Use the fins to align it properly. Step-4: Slide the doser adjustment gear toward the front of the machine until it stops. Step-5: Before replacing the bean hopper, rotate the grinder adjustment wheel to Zero (0), and the doser adjustment wheel to Minus symbol (-). Place the bean hopper into position on the machine, slightly adjusting each adjustment wheel as you are placing it down in the machine. Once in place, fasten the bean container with the 3 screws. Test each adjustment wheel through the full range of motion. The grinder knob rotates from 0 to 18 and back, and doser knob from Minus (-) to Plus (+) and back. Now position the grinder adjustment knob at Eight (8) and the doser adjustment knob to the halfway point between the Plus (+) and the Minus (-) marks. This will put the machine back to the factory setting. When using for the first time after adjusting the grinder, it may take more than one grinding cycles to make the first cup of coffee.
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.
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.
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..
Follow these instructions to put grinder back together...
Items needed to clean grinder
1- #2 Phillips head screw driver
1 Cleaning brush
Remove all beans from the bean hopper, vacuum out any
beans that cannot be scooped out by hand.
Remove the front and back screws and pull off bean hopper
container from the machine. (Note: The rear screw is longer
than the front screw.)
Note: Doser adjustment knob is available only on Vienna
Digital and Vienna Deluxe Rapid Steam.
Place screws in a safe place so that they will not be lost.
Cleaning the Grinder Viennas
Before beginning to clean the grinder please be sure to turn the machine off and unplug it from the wall
socket. Grinder Tip: Using an oily bean will cause the coffee to build up quickly and clog the grinder.
Saeco recommends using a medium to dark colored bean that is not oily.
After cleaning the grinder and then brewing a cup of coffee it may take 2-3 grinding cycles for the machine
to dispense coffee.
Remove the black rubber gasket, then vacuum additional beans or grinds from the grinder area (Fig. 1).
Rotate the outer ring of the grinder counter-clockwise until the red line is at the 12 o'clock position (as
viewed from the front of the machine) or until the red line on the outer ring is 180º from the opposite red
line on inner burr ring (Fig. 2).
Lift the inner burr ring out of the assembly (Fig. 3).
Figure 1 Figure 2 Figure 3
Vacuum out any residual grinds from inside the grinder and clean the grinder burrs using the cleaning
brush (Fig. 5). Clean out the grinder coffee chute using the end of the cleaning brush (Fig. 5).
Remove the drip tray, open the service door, remove the dregdrawer and brew group. Gently pull
down the coffee doser door and brush out any ground coffee that may be inside the chute (Fig. 6).
Be sure that the red line on the outer ring is still in the 12 o'clock position. Place the inner burr ring back
into the grinder making sure the red line on the inner burr is at the 6 o'clock position or 180º opposite from
the red line on the outer ring (Fig. 2). Once the inner burr ring is in place, rotate the outer ring clockwise
until it will not turn any further. At this time the two red lines should be aligned. The grinder is now at the
"0" position. Replace black round rubber gasket (Fig. 7).
Take the bean hopper container and rotate the grinder adjustment wheel to zero (0) (Fig. 8) and the doser
adjustment knob to the minus symbol (-) (Fig. 9). Slide the doser adjustment gear toward the left of the
machine until it stops. (Note: The Vienna Black does not have a doser adjustment knob. Only the Vienna
Digital & Vienna Deluxe Rapid Steam have a doser adjustment wheel.)
Reinstall the bean hopper container being sure to use the LONG screw in the back, then replace the finger
guard using the short screw in the front of the container. Once the bean hopper container has been
reinstalled, rotate each knob through the full range of motion. The grinder knob should rotate from (0) to
(18) and back, and the doser knob from the minus symbol (-) to plus symbol (+) and back.
Place the grinder adjustment knob at the eight (8) position and place the doser knob at the halfway
point between the plus symbol (+) and the minus symbol (-) symbol, or to your preferred settings.

First, unlock and unscrew the upper burr carrier. Clean and check the upper burr by gently running your finger over the teeth in the cutting direction. It shoild feel moderately sharp. If it feels very blunt, look at the teeth under a good light. If you see a substantial "flat spot" at the top of the teeth, probably the burr set will need replacement.
For the bottom burr, clean carefully its teeth, and the entire area in which it is housed. Include the outlet orofice as well. You may find a lot of oily deposits within here, so just clean them off as best as possible.
When all is clean, insert the top burr holder back in place. Screw it down until both burrs touch, then back it off (say) 1/4 turn, and lock.
Put some beans in the top, and switch on. Adjust the top burr until the desired grind is obtained.
The ground coffee should feel like a coarse sand when close to the desired grind size.
