Re: No power

We have had the same problem with the grinder not working. The front base of the main unit has a small slot. Inside the slot is a safety switch. The switch is closed when the coffee ground container is inserted into place. You will also see the small blade on the front bottom of the container which activates the safety switch. I just used a small toothpick and cleaned any debris from the slot and exercised the safety switch by gently pushing it back a number of times.

You can test the unit by taking the coffee ground container out and set it aside. Position the coffee amount slide to any number just so it isn't in the off position, then hold the on bar down and take the toothpick activate the safety switch in the slot on the front of the base of the unit. It worked for me. I didn't see anything obstructing the switch but it is dark and hard to see in the slot. I possibly dislodged some coffee grounds or something which restricted the switch movement.

Re: No power

The other safety switch is under the hopper. If it isn't screwed down enough, it won't turn on. To ensure this doesn't happen, screw down the hopper all the way, then back it off to the setting you want.

Why does ground coffee not go thru shoot

If using Beans; it is set to fine and due to static it sticks - OR you have a blockage..

If you are putting ground coffee into a grinder; the static will be a bigger issue and in addition there is no weight from the beans to press the grinds into the burrs. A bean grinder is not ment to grind beans that have already been ground.

Get a better grinder and do not buy supermarket beans.

Cleaning burrs of oily residue

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 purchased a GE Coffee Grinder Model number 111338 54, but there wasn't an owner's manual with it, and the first time we plugged it in it doesn't work. We just wanted to make sure we were operating...

I'm on my second grinder of this model.......... in the past 2 months. The first stopped working so I just took it back and replaced it. The second time it quit working I removed the cup with the grinded coffee and noticed smoke wafting up from the unit. Both times it quick working I was grinding 12 cups of beans (12 cups of brewed coffee, not 12 cups of actual beans). The unit shouldn't have a setting to grind that much coffee if it burns the motor out, which is what happened.

My cuisinart cbm-18 does not grind at below a 10 setting?

Hello, and thanks for using FixYa.

I'm guessing the problem is that the grinders blades, or the parts that do the grinding have become somewhat dull, (opposite from Sharp.) and no longer can get to the beans like it used to.

Cleaning the machine properly might improve its performance.

1. Be sure plug has been removed from outlet.

2. Beans can be removed from the hopper by lifting off the lid and pouring excess beans out. Hold down the Manual button to cleanout any remaining beans.

3. The bean hopper, bean hopper lid, grind chamber, and grind chamber lid can be washed by hand with hot, soapy water or placed in the top shelf of a dishwasher. Dry thoroughly.

a. Remove the bean hopper by rotating counter-clockwise bringing the selector past grind setting 18, align the arrows and lift up. Make sure the hopper is empty.

b. Remove grind chamber by pulling toward you.

4. Remove the burr grinder, once the bean hopper has been removed, by grasping the metal handle and lifting up. Use the brush to remove grinds or wash by hand. Replace the burr grinder onto the unit and rotate until the piece is fully inserted. Push handle down and replace hopper.

NOTE: The hopper will not attach to the unit if the grinder has not been fully inserted.

5. Wipe body of grinder with a damp cloth.

6. Any other servicing or maintenance should be performed by an authorized service representative.

My mazzer coffee grinder brings out medium to almost a whole bean grinds ,,,am trying to get a fine grind(for the espresso) but it's not working ,,, i've tried to move the scale to all the numbers but the...

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.

All of sudden my grinder plugs up. coffee settles in around the base of the burr and does not seem to fall into the grind bucket, so the machine still runs but grinding basically stops as no more more...

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).

Extremely course grind

Remove bean hopper, clear chamber of all beans, either by grinding or using a vac cleaner, then turn adjustment collar finer until it cannot move, then back it up about 1/4 to 1/2 a turn. That should give you a good starting point on your grind.

Braun Aromatic KMM10 stops grinding

Soulds like a thermal overload breaker? I know you should not have to do this . Use an outlet that is not shared with any other item, if one is available and if there is a selector for different grinds see if changing it to a finer grind will help. A couarse gring takes more bean ion each pass and it may be too much load on a single extended grinding. One would think the bigger the bin the better the motor. But try this and if you will, let me know. please

Grinder starts up but wont grind..nothing happens. one week old

I think this might be because no beans have gone down into the mill. There is a definite difference in sound when it is actually grinding beans. Try emptying the beans out, set it to the coarsest setting, put the beans back in, shake the thing a bit then turn it on.

Cuisinart burr grind and brew coffee maker

The hopper between the burr grinder and where coffee chutes into the filter is jammed with coffee powder...

First, take out the filter holder and carafe, and place a freash empty filter on the pot base to catch stuff.

Next, take out the beans holder and look for the release lever in the lower left section. Sliding it to the left slides open the door, where you'll probably find loads of powder. You can poke your finger through to get the majority, then use the cleaning brush to get it really clean.

Thanks what fixed mine! (I notice I have to do this about once every few months.)
