La Pavoni coffee grinder fine/coarse adjustment

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.

Is this the right one?

If not, I would go to http://www.lapavoni.com and find the service center that is closest to you and call them on the replacement part.

Sorry, but there just doesn't seem to be any La Pavoni replacement parts carried by any of the American suppliers.

BURRS are the metal parts that grinds the coffee. There are 2 BURRS in the grinders, The upper burr is normally the one you adjust (Fine or coarse) and the lower or closer to the motor is the one turning during the grinding process.

Lets do this, remove the bean hopper, and make sure there are no beans in the burr chamber. Then looking down at the collar with the numbers back up screw if there is one on it. Now if memory serves me right clockwise is coarse and counter is fine. Look down in the burr chamber, notice the nut in the middle, turn it with your fingers that will move the bottom burr, if burr turns freely we will move on if not plug in grinder and let it grind out remaining beans. With beans gone unplug grinder, then turn collar towards fine until you cannot go no more, now try turning nut it will be hard if not impossible to move, turn collar towards coarse until you can barely move bottom burr with fingers, you will hear and feel the burrs touching, that will be our bottom setting. Now pick a spot on the grinder you can use the small notch in the middle, count out 16 notches towards coarse and turn collar to that point. Use the notches around the collar not the ones on the top next to the numbers. Your grind should be almost perfect, depending on blend and machine you might have to adjust 1 notch to the left or right after testing.

It would be easier to pick up the manual in the commercial section under products from bunn.com, rather than me explaining it.
You have to loosen the nut on the adjustment wheel, then pull out slightly and turn towards coarse a few numbers, then push back in and turn grinder on and slowly turn toward fine, until the burrs slightly touch, you will hear a little metal on metal, at that point turn the grinder off, back off about slightly, then pull out adjuster and turn it to Turkish and tighten screw.

The current Kitchenaid A9 burr grinder glass jar is interchangable with the original Hobart/Kitchenaid A9 glass jar; therefor, the gasket should also interchange - contact Kitchenaid customer service to order a gasket.

Setting the grind is accomplished by grasping the body of the ginder in one hand and the grind-selector ring (collar that the jar screws into) in the other. Hold the base tight and turn the selector ring clockwise for a finer grind, counterclockwise for coarser. Be careful not to completely unscrew the selector ring; if you are not sure how much adjustment is left, screw it all the way clockwise until it stops (finest grind); then, back it off, up to one full turn to make the grind coarser.

The selector ring has the words coarse, medium and fine cast into it; these are rough postition markers. There is a triangle cast into the body of the grinder, just above the brand name, that can be used to diral in a preferred level of grind. I use a medium-coarse grind for drip coffee makers; to do likewise, position the selector ring so that the triangle is pointing midway between the words coarse and medium.

usualy reserable termic fuses are attached to body of motor, or inside the winding wires of motor.

1. if it is attached to motor body than you should reset yourself, usualy they are black, round colour with red reset button on center. it is enough to push that red button and you reset it.
2. if it is in winding wires it should reset when motor temperature drops, if that is not the case than you should consult winding expert for that, in your region.
   

You'll need to remove the hopper and grind out all the beans. Then, with the lock tab depressed (if it has one), unscrew the grind adjusting collar out of the body. Once it's out, there are three screws (sometimes only two) holding each burr. Remove screws and separate the burrs. Clean away!
Be very careful putting it back together so that you don't cross-thread the collar into the body. Clean threads can help this.
Good luck!
