I just purchased the 4KPCG100PM1 kitchen aid burr grinder.Looks like a nice unit but on the finest setting it is far to course for espresso. Can it be adjusted to a finer set of 15 positions by repositioning the adjuster within the unit.

Re: Kitchen aid burr grinder adjustments
You are correct, the grider positions are locked internaly so the grinder will not go too fine since this can damage the blades and also too fine need more power from motor and also can block it by rottating normaly. However you ir open the grider you can overcome the lock and udjust so the grinder can grind more fine coffee. In order to be always at the safe side just move gradualy step by step until you find the perfect grinding and adjust so that will be the minimum plus one mor move for furure adjustment if you need.
Just for reference the corect grinding is for 7 to 7.5 gr of coffee the running time of the coffee from your machine should be 25 sec for 25 cc of coffee aprox.

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.
To adjust this grinder turn the adjustment nob to the finest setting (ESPRESSO or TURKISH) Locate 2 small set screws on the adjusting nob. Loosen these screws (do not remove them) about one full turn. Start the grinder and, with it running, VERY SLOWLY and GRADUALLY, turn the CENTER adjustment screw clockwise until you begin to hear the burrs begin to touch (whirring sound). Back off the center screw about 1/16 of a turn, shut of grinder and re-tighten the set screws. Then try the grind on DRIP or there about for brewed coffee.
This model grinder won't do espresso. There is a DIY mod available online that involves disassembling the machine, and recalibrating the burrs to produce a finer grind. I did it on mine, it was definitely better, but it's not going to get you to the coveted 30 second pull for your espresso. Search on Starbucks Barista Grinder Mod. It is a great grinder otherwise, very reliable.
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.
because it didn't work a wilde the upper burr holder could be jammed, carefully take id off, clean it good and then put it back until you touch lower burr with the upper.
to get starting point you adjust burrs to touch each other. when they
touch each other you have finest grinding, after you hear metal voice
you turn back 3 dots and grind only for 1 dose. you check it, if it
goes to slow, you go one more back and clean grinder, THAN you grind 1
dose more. 2 or 3 times and you will get perfect grinding.
if upper burr holder and the body of grinder does not hold stabile, teflon aplying does not help too much, it is only temporary solution. new upper bur holder would do better.
before inserting upper burr holder you should check if lower burr is rotating syncronized, you should take a bit chalk and sof touch while burr rotates. after that you stop grinder and look do you have circle with same thiknes, that would give you idea where is the problem, if it is in lower burr.
I'm thinking that there is something in the burr in the unit. Empty the unit and remove the burr. Usually, this is done with a counterclockwise turn. Note how hard it may be to turn...you'll have to reverse this when you put it together. Now, clean out any coffee debris you find. Then, turn the unit over and tap it on a firm surface covered with newspaper. Reassemble and return to service.
