Grinder problem Grinder more often than not continues to grind. It will not turn off until you switch it off.

they usually keep grinding until the compartment with the grinded coffee gets full or until you turn off grinder. should turn off after compartment reaches full state.

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.

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.

Try this, remove the bean hopper, and vac out the burr chamber, then put 1 tablespoon white rice in the burr chamber and cover with hand and turn grinder on, if the rice grinds, then your grind might have been set too fine. Turn the grinder towards fine until you can barely turn the burr nut, you will feel them touching, then turn course about 16 notches (do not use numbers, use the small notches around the rim), that should give you a great starting point for your grind.

Mine was doing that for the past week. I think it was indicating there had been a power outage but that the clock had not reset to zeros. I changed the time a couple of minutes and it stopped.

Hi
You have a micro switch on the doser that is in need of a replacement. It is a special micro switch that is just for the doser. It is very sensitive. If the micro switch is not activated the grinder will run until it times out, but the coffee will fill the brew unit and that could break the brew drive.

Hi
thedalys. you probably have a bad micro switch on your doser. and that just needs to be replaced. If the grinder does not sense that the doser box is full it will keep grinding until it times out.

Guest. Try pulling the dosage lever back one click from the full and push your grind lever to the largest # and see if that helps. Sounds like you grinds are too fine and its clogging the the grind box. If the dosage level is too full it will cycle and dump the brew unit or break the brew drive gears, then you will hear a clicking noise when it trys to make a coffee.

Hi,

It can be the micro switch in the machine you have to replace.
If you take off the top you will see it where the hole for the beans are.

It is possible that the relay, or the micro switches on the grinder are defective.

Turn adjustment ring towards fine, until it cannot move, then back towards coarse about 5 numbers, that should give you a good start on the grind.
