Humm, G-3 grinders. Okay what common problems I've come across:
* Wrong setting for grind on label. Usually means worn out grinder burrs. But this does not happen often unless you are using it to grind commercial amounts of coffee? It's a retail level grinder meant to be user friendly and simple to use. Say grind a bag of beans once every 10 mins or so even with customers lined up to grind there own. Running a G-3 constantly is usually done by upcoming coffee vendors whom are using it for small flavored bean batches. But expect the burr plates to only last 3 to 6 months. We used to change it every month till the boss bought a bigger pro grinder. (whew!)
* Out of calibration (for grind) This usually happens as soon as it's installed. Either the grinder got banged (Dropped?) around or the lock nut was not tighten down. If caught quickly then it's a simple adjustment. Left unchecked will wear out the burrs or crack the plate.
* Trips out breaker. This is common at retail stores as it's located in a shelf rack that really does not have the required outlets. Many times there is a brewer(s) connected to the same line. It only trips out when one or both brewers are heating and the grinder is running a very fine grind.
* Trips out breaker when grinding espresso or very fine grinds. Worn burrs or slim chance the grinder was miss calibrated (but you would catch this when first installed)
* Shocks the customer. Dry climates or heavy air conditioning will build up static electricity at the chute. There usually a small chain attached to the chute to prevent this. Attach a SHORT metal chain or thin cable to the metal case of the grinder and add a metal clip to attach to the coffee bag. Many use a chain and clip just short enough to keep the bag positioned under the chute. Note many coffee bags come with bag clips. Just make sure the clip and chain can't get stuck in the grinder.
* Not working. This is usually the on/off switch as it gets beat up the most. There is sometimes a safety micro switch under the chute to sense if there is a bag there. I've found may have been defeated.
* No power, check cord, breaker (GFRI) outlet, Plug prongs if broken off or bent.
* power but no motor hum. Tripped thermal breaker (usually a red button on side or back. Some models may have it inside on the motor itself. Call for service to check.
* Turns on but loud hum (may be hot too). Burrs stuck. This could be from adjusting grinder while grinding beans and adjusting to a fine setting. Grinding finer slows down the beans feeding the burrs. Large settings flood the burrs with a lot of beans. Adjustments are usually done when the grinder hopper is completely empty. If loaded and turned down from coarse to fine grind the beans already in the burrs get crushed and stuck between the plates thus locking them in. It may be possible to clear the hopper and open up the grinder to its coarsest setting to jog out the crushed beans. Otherwise call for service to have the burrs cleared manually.
*Finally check with your vendor if your still having problems.
This can be caused by several things;
If it used to be good but is now faulty it is most likely that it just needs cleaning. If you are using beans that are 'oily' they can clog the grinder, you should anyway disassemble it and clean every year. Do not use soap and water, just brush it with a stiff brush (e.g. the stiffest type of toothbrush) and a vacuum cleaner.
There is also a possibility that something has got into the grinder along with the coffee beans that has damaged the grinding wheels; in that case you need to replace the wheels.
If this is a pour-over coffeemaker, you can't do anything about the flow. It's just gravity pushing the water out of the reservoir. But you can try using a coarser grind of coffee. If the grind is too fine (if you grind whole beans for too long in a blade grinder, for instance, or if you're using espresso grind coffee), the water can't flow through quickly enough and it backs up and overflows. Make sure your coffee is ground for a drip coffeemaker.
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.
First, you should call Cuisinart (800-726-0190) and see if your product is still under warranty. They may fix it for free. I was told that certain beans sometimes won't grind up fine enough to get through the screen in the grinder because of the oil in the bean. So first thing you can try is to freeze the beans and then try grinding them. If you have still have the problem, you either have an issue with your grinder or the grinder motor. You can buy a replacement grinder on Cuisinart's website for about $20. If its not the grinder, and its the motor the only thing you can do is find a spare motor online somewhere (impossible to find since they don't make spares for the motors; the only way to get one is from someone who has taken apart the same model for the parts). Hope this helps.
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).
