Hi
I would suspect that the burrs have never touched. There has to be some coffee grounds in the threads that is preventing the burr assembly form going in any farther. Remove the burr assembly and check the threads inside the chamber. If there is any black coffee residue it has to be removed. It sometimes has to be chipped out of the threads. We used a dental probe to remove it. Then a tooth brush. When reassembling the burr assembly turn all the way in until you see the acorn nut in the center rotate. STOP. Back the assembly back until the nut stops rotating. That is ZERO. You can install the bean hopper with the zero facing the mark. You can also move the assembly a little counter clockwise, but not clockwise, to line up the screw holes. Make sure that you have the hopper stop in place before tigntening you screw down. Then turn the bean hopper to 7 and test.

1 take the bell(bean container) carefully out. 2 disassemble the upper holder of burr 3 you will see now the burrs, clean good coffee remains than disassemble the burrs 4 after disassembling burrs clean good the lower and upper burr holder. 5 carefully switch on the grinder tan switch off(few seconds) during lower plate is rolling touch with marker the surface of burr holder very softly, if it is ok you will have complete circle / if it is deformed you will have incomplete circle( that you must compensate with letter tape ) after each correction you mark the burr with marker to see did you achieved perfect result. once you have lower burr in place you screw bolts in upper bur holder and assemble it back in his place.

Hi
If you only got the lower burr it won't work. They should be matching burrs.
If you don't do it right, you will damage the grinder. You need a #10 Torex bit.

Insert the bit into the screw in the middle of a very clean grinder. Turn clockwise to loosen. Once the screw is out, pull the burr out, but be careful. There are ball bearings and springs under the burr. Make sure that everything is clean before reassembly. There are 3 holes in the bottom of the grinder. The springs go into the holes first. Then the ball bearings set on top of the springs. Place the new lower burr on top of the springs. A washer and the corkscrew go in next. Insert the screw in and with the bit in place turn (with a little down force) clockwise until the screw drops into place, then turn counterclockwise. It should turn fairly easy. Once you start putting pressure on the springs, try to turn the corkscrew. There is a notch that it slips into in the bottom of the grinder. Once it locks into place keep turning the screw until you start to turn the burr. That should be tight enough. Now reassemble the top burr and adjust.

For parts you can see, use an artists paintbrush. If you want to clean the internals, grind some panko breadcrumbs or raw rice grains, then run some coffee through it a few times before using.

This is a set screw. You need to take this out.
You can access this to either clean the burr
grinding wheel. Maybe this needs changed.
If you google the Kitchenaid A-9 Burr grinder you can get instructions to download on this machine.

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.

1. take out bean container
2. disassemble 3 philips screws and take plastic out
3. rotate the knob to try to get out the upper holder of burr. if it does not rotate than disasemble the knob and the gears(plastic big one is attached to upper holder of grinder, the other is together with knob.
4. tru to rotate it manualy, with help of extra srews puted in gear holder holes.
5. when you get it out, carefuly clean it, look for metal parts and stones(wich sometime comes with coffee)

1. turn on the grinder and attach gently one marker to lower burr during spining. after you stop grinder, look if it is perfect circle marked in burr. if it is not than marked side is higher. you should consider getting it ok by putting adhesive paper under lower burr and check it again.

good luck and carefuly.

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!
