Likely causes are grinder has burnt out or temperature cut-out for Grinder has blown. Either can be replaced as a spare from Miele.

Make sure the hopper is working correctly to see if there are any blockages, then check under the hopper to the opening where the beans go to the grinder. My guess is that there are a few beans and chipped portions of beans which are clogged under there.

Cuisinart coffee grinder keeps clogging


Unplug first. Unscrew the top. You need a long thin screw driver Phillips head is the best. Pock around the exit and entrance where the coffee beans are ground. Remember, the better the coffee and you will get more clumping of the beans. I works great. It is pain. The Chicago Clout man exits.

The bean grinder doesnt grind, only water comes out


If it is working before, probably the coffee chute is clogged up. You can remove the bean hopper and see where the coffee drop into the brew unit.If the chute is still attached just clean the blockage, if it is broken you will have to remove the grinder and replaced it.

Coffee beans empty


Hi
Coffee beans empty is caused by the grinder running for about 15 seconds without filling the doser chamber. Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside on the roof of the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. From the left side of the drop chute pull down and back, and it will drop coffee. This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute.
Once that is cleared go to the bean hopper. There is a lever on the right side of the bean hopper. Push the lever back to the largest number. You can push the lever to a larger number any time but it has to be grinding to pull to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can pull back to a number that was higher than the one you had it on, but only when the grinder is running.

I bought new green coffee beans recently, roasted it myself and wanted to use it in the machine but the grinder gets stuck and won't turn. The new beans are harder and smaller than the type I used to have....


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 restart.)
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).

Hello. grinder won't grind


HI
Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. This will be above where the brew unit was. From the left side of the drop chute pull down and back, and it will drop coffee. This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute.
Once that is cleared go to the bean hopper. There are 2 knobs in the bean hopper. Turn the large knob to the largest number. You can turn the knob to a larger number any time but it has to be grinding to turn to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can turn the knob back to a number that was higher than the one you had it on, but only when the grinder is running.

My A-9 Coffee grinder no longer grinds coffee. Have cleaned it and checked it out and nothing. The motor runs but no grounds. Thanks for your help!

Remove brew unit and check the grounds chute from the grinder, if that is clear, then re-insert unit, then when the grinder is grinding adjust to a coarser grind.

Cuisinart 12-cup grinder coffemaker all gummed up


It is endemic to this unit - condensation builds up in the grind chute, which makes the grinds stick to the walls of the chute. Decalcifying with vinegar/water helps, but only in an indirect way - by keeping the inside tubing clean, decalcifying generally allows the water to flow through the machine without obstruction. Inside tubing that has calcium, lime deposits built up obstructs water, and makes it flow through the machine slower - when water flows more slowly through the machine, the machine steams off the water at a higher rate, hence more condensation builds up in the grind chute walls.

Generally, i have found all Cuisinart coffee and espresso makers to be high maintenance to a greater or lesser extent, but the Grind-n-Brews have the highest cleaning/maintenance requirement.

Grinder setting stops at drip. Can't turn further to espresso.


Another suggestion is while the grinder is off, turn it up side down and rotate the bean hopper from coarse to fine a couple of times. This will clean out grounds that have gotten into the threads and it will prevent the bean hopper from not turning to a finer grind.
If you start to get a clog in your grinder, open it up to a coarse grind for a few seconds. The coarser grind will clean out the chute and then you can turn it down again while it is still grinding.
