My 12-cup grind and brew stopped grinding. I hear a grinding noise, but no grounds enter the filter basket and the coffee therefore comes out clear.

How can I flush it if it won't brew at all? ..... The filter basket is in the proper position for the coffee to enter the filter but the ...

The pot brewed a good cup of coffee but as of now it is useless.

try to fill the reservoir with the water to the top, when the water starts "brewing" the water is transfer from this reservoir to the basket where there is loose coffee placed over the paper bag that will filter the coffee to the jar.
Check if anything is blocking the canal, that is transferring the water from the reservoir to the basket.

Put the handle to the basket, that holds the coffee grounds toward the front.  If it is not facing front it will pop open.

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. Ensure you are using the correct grind for an automatic drip coffee maker, neither too fine nor too course. (See instruction manual.)
3. Do not overfill with water. Use the carafe to pour water into the reservoir. This is because a "cup" in coffee terms is defined as 6 oz, not 8 oz.
4. Make sure the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. Clean your machine with vinegar or as instructed by your user manual at least three times per year, more if your water supply is hard. A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew, to produce "off" tasting coffee, or to clog and overrun the filter basket as the water runs through the grinds.
9. Ensure that the coffee machine is sitting level on the counter.

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. If self-grinding your coffee beans, ensure you are using the correct grind setting for an automatic drip coffee maker. (See instruction manual for coffee maker and/or grinder.)
3. Do not overfill tank with water. Use the marks on the side of the reservoir as a guide rather than those defined by another measuring method. This is because a "cup" in a coffee carafe is defined as 6 oz, not 8 oz, and in some cases as little as 5 oz as a cup. As such, a 12-cup machine actually produces closer to 9 standard 8 oz cups. (See your owner's manual.)
4. Make certain the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.

8. It is extremely important to clean your machine with vinegar or as instructed by your owner's manual at least three times per year, more if your water supply is hard (prone to leaving water rings). A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew a pot of coffee, to produce "off" tasting coffee, or to clog and overrun the filter basket.

If the water is not coming out of the filter basket, and is instead leaking over the edges, then replace the brew basket.

If there is no water at all, call Cuisinart - those coffee makers have a 3-year warranty.

Some fine-grain coffees are too fine for the Gold Tone Filter. If this is the case, remove the Gold tone Filter and use paper filters only. You may have to wash excess grinds out of the black filter basket, since there may be a few stuck in there now - don't take the filter basket apart - just rinse it out with water.

Also, don't use a paper filter and the gold tone filter at the same time.

Good luck!

Make sure you are not using the paper filter and the permanent filter at the same time. Make sure the chute undernetah the grind basket is clear of grounds, moisture.

Pot must be inserted with the handle pointing straight out the front so it will hit the valve that is below the basket designed for the "rob a cup" while brewing feature.
