Cuisinart is one of the well-known makers of home appliances in the market. They offer a variety of coffee makers from drip, and brew, to grind and brew/drip coffee makers.
While Cuisinart manufactures good quality brewers, the machine can have some issues arising from its daily use, setup, or for any other reason. Troubleshooting these issues can often resolve the problems, without the need to incur huge expenses on repairs or replacements.
This guide shows the various steps to follow to help clear some of the common issues with Cuisinart coffee makers.
Why is my Cuisinart coffee maker not brewing?
If your Cuisinart coffee maker won’t brew, it could be because of an air bubble that is trapped in the water path. Below are the other possible causes for the problem:
Calcium buildup due to the type of water you use could be a reason why your coffee maker is not brewing.
Pot is not centered
Many coffee makers have a small valve that withholds the flow of coffee if the pot is not centered to prevent coffee from dripping out onto your countertop.
It is possible that the wiring has become faulty or has been compromised and no longer functions. This could be noticeable by the on/off light no longer illuminating once the machine is plugged in and turned on.
The unit is not plugged in.
The reason your coffee maker is not brewing could simply be because you haven’t plugged it into a working electrical outlet.

This indicates the water level in the reservoir is low and water must be added in order to brew a full cup.
How do you reset the clean light on a Cuisinart coffee maker?
If the Clean light starts to flash when the coffee maker is turned on, it is telling you that the calcium buildup is interfering with the functioning of your coffee maker and the flavor of your coffee.
To reset the Clean light, you need to clean your coffee maker using the same procedure:
- Fill the water reservoir to capacity with a mixture of 1/3 white vinegar and 2/3 water.
- Press the clean button. When the self-clean light glows, turn the coffee maker on by pressing the on/off button.
- The Clean light will shine steadily. The coffee maker is now in clean mode. Once cycle should be sufficient to adequately clean the coffee maker.
- When the cycle is complete and the five beeps sound, the coffee maker will shut off. Turn the coffee maker to see if the Clean light continues to flash. If it does, repeat the cleaning procedure with a fresh solution of vinegar and water.
- If the Clean light no longer flashes, turn off the coffee maker and then run one cycle of fresh cold water through the unit before using the coffee maker again to brew coffee.

How to Clean Cuisinart Coffee Maker
Follow these instructions to clean a Cuisinart coffee maker:
- Always turn your coffee maker off and remove the plug from the electrical outlet before cleaning.
- Lift the reservoir cover. Remove and discard the paper filter and ground coffee.
- The filter basket can be washed in warm, soapy water and rinsed thoroughly, or cleaned in the upper rack of the dishwasher.
- Dry all parts after use.
- Do not put any water in the unit once the filter basket has been removed. Wipe the area under the filter basket with a damp cloth.
- Remove the carafe from the heating plate. Discard any remaining coffee. The carafe and lid can be washed in warm, soapy water and rinsed thoroughly, or placed in a dishwasher. The carafe and carafe lid should only be placed on the upper rack.
- Do not use any harsh cleaners or scouring agents on any part of the coffee maker.
- Never immerse the base unit in water or any liquid. To clean the base unit, wipe with a clean, damp cloth and dry before storing.

Coffee tastes metallic
Metallic-tasting coffee is a common problem with older machines. The metallic taste can generally be solved by cleaning your coffee maker.
Follow the cleaning instructions as per your unit’s manual, but in general, the cleaning procedure for all the internal components is to add 1/3 part white vinegar and 2/4 parts water to the water reservoir and run it through a brew cycle.
Run several more brew cycles with water only to clear any residual vinegar.
A dirty carafe could also be the culprit for bad-tasting coffee, so give it a thoroughly clean as well. Let the carafe sit overnight filled with 1 part baking soda and 2 parts warm water to remove any stains, and then rinse with water in the morning.
Cuisinart coffee maker stops brewing middle cycle
Try the troubleshooting tips below if your coffee maker stops brewing middle cycle:
- Check the basket/pot and whether it is centered. Adjust the basket to make sure it is sitting straight or remove then replace the carafe or pot to make sure it is sitting in the center of the drip dispenser.
- Use a toothpick or run the coffee maker with vinegar in the water reservoir to clean out any calcium deposits that may have buildup. If you successfully clean the unit and decalcify it, ideally you should run a couple of cycles with only water before adding coffee grinds.
- Check if there is water in the reservoir chamber and if there are coffee grounds in the basket. Add as required if there isn’t.
- Check for coffee ground buildup under the blade. If there is buildup, thoroughly clean it. Soak the grinding bowl in hot soapy water and scrub it with a small brush. Also, remove any beans or grounds from underneath the grinding bowl and clean that area as well.
Cuisinart Coffee Maker is Overflowing
If your machine is constantly overflowing from the filter basket, you may be filling your basket or using coffee that is too finely ground, which causes the drip to slow and the filter to overflow. For example, for 12- and 14-cup coffeemakers, Cuisinart recommends filling the basket with no more than 15 tablespoons of coffee grounds to avoid overflow.
Also, try these additional tips to fix an overflow problem with your unit:
- Try reseating the pot to make sure the lid is in the correct place.
- Check to confirm you have forgotten a paper filter. Check whether you have accidentally used two filters and clogged the filter basket

- Reset your home’s circuit breaker.
- Confirm the power has been turned on and the LCD illuminated.
