I took everything apart to give it a good cleaning and now all settings produce a very fine grind. Any thoughts?


I had the same problem with too fine a grind when I took mine completely apart to clean (including the lower burr). The solution I finally came around to was to further tighten the star-shaped screw which holds the lower burr assembly in place. I had originally just tightened it until the lower burr until the lower burr assembly started to turn with the screw, but that wasn't enough. So I held the assembly in place and tightened the screw further and I'm back to my previous grind coarseness/fineness.

The coarse grounds is definitely the problem. make sure your machines setting are near 5-8 depending on the beans you use.

You need to make 5 cups of coffee before you see the new grind size. Do not change the grind too often or you will not see what you are looking for.

If the coffee is still too coarse you may need to replace the grinder burrs. http://www.cerinicoffee.com/grinder-burrs-saeco-gaggia-asp.html

or you should take it to a service center.

Grinding makes a lot of scratch noise and coffee wouldn't drip. The machine says to fill the beans but container is full.


Likely a foreign object is blocking up the grinder. Remove all beans and run at coarsest grind to try to clear it, chase it through with more beans if necessary. If this does not clear it then the top burr of the grinder assembly can be removed after disassembling the machine. Mark the grinder coarseness cogs before moving them to assist reassembly. Moderately difficult procedure.

Cleaning burrs of oily residue


Hi
There are many ways to clean oily residue from your burrs. You can order a grinder cleaning tablet from online stores called Grinds by Urnex. Some people use white rice but if you don't get it all out you will have rice in your coffee. You can take them apart and clean them manually but if you don't reassemble it correctly you will not get a good grind. I think the easiest way is to get some cheap light roasted beans ( doesn't matter if they are old ) but never use shiny beans because shiny beans have lots of oil.
Set the grinder to a very coarse setting, on a Rocky 7 higher that you currently use. You can turn it to a larger # any time but it has to be grinding to turn it to a lower #. Pour a cup of cleaner (beans, or rice) into the bean hopper and turn the grinder on. Grind the whole hopper through the machine. If you use grinds just a couple of #'s higher is all you need. Once you have cleaned the burrs you will need to grind some of you beans to purg the cleaning debris for the burrs and chamber. When you see no more cleaning compound you can turn the hopper back to where it was leaving the motor run. Once you get it back test with your beans.

I would suspect a log in the outlet shute where it goes into the grinds hopper. Clean it out and then turn the hopper to the coarsest setting to clean it out all together. Coarse grinds are a very good cleaner.

Oily beans seem to have clogged our coffee grinder up. What can we do?


Rotate the bean hopper counter clockwise until it stops. Lift it off. Remove the outer burr with the 2 wings and clean under the burr. Clean the opening going to the chute for ground coffee(inside where the burr was).
Install the outer burr. Install the bean hopper. Rotate the bean hopper to the French press grind (coarsest) and operate the grinder. This will clean the burrs and the passages. If it starts to clog, repeat the last part to clean the burrs and passage. It must be grinding to go to a finer setting, but you can go to a coarser setting any time. Another thing. Turn the grinder upside down (empty) and rotate the bean hopper back and forth to clean the threads of the adjusting burr..

Hi
Oily beans (shiny) can some times stick together after grinding with a fine setting. Try opening the grinder setting to the very coarsest setting and see if it will clear the passage. If you have pushed the brew button an lot of times you may have packed the grounds in the passage which will have to cleaned manually.
Once you have the grinder working again, open it to the coarsest setting to clean the burrs. 1 time is enough. To turn the grind setting back down to your setting make sure that the grinder is running at that time. You can open to a coarse setting any time but it has to be running to finer.

Parts and Grind Selection


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.

Love your 'handle'!

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.
