Understanding Descaling and Its Importance

Limescale, a hard mineral deposit (from calcium and other minerals) that accumulates due to heating hard water, can affect the performance and taste of your coffee. Descaling, or decalcification, is the process of removing limescale buildup and is vital for maintaining optimal water quality and prolonging the lifespan of your coffee maker. Regular descaling ensures that your Cuisinart Coffee On Demand coffee maker continues to deliver delicious coffee. How often you need to descale your Cuisinart Coffee On Demand Coffee Maker will depend on the hardness of your water and how often you use your coffee maker. The “Clean” light on the base unit will flash when it’s time to descale the coffee maker.

How to Descale Your Cuisinart Coffee On Demand Coffee Maker in a Few Simple Steps

Step 1: Gather Your Materials

To descale your Cuisinart Coffee On Demand coffee maker, you’ll need:

  • A descaling solution recommended by the manufacturer, such as K&J, or use a vinegar solution made of 1 part distilled white vinegar and 2 parts clean water.
  • Clean water

Step 2: Prepare the Coffee Maker

Ensure that your coffee maker is unplugged and cooled. Remove any used coffee grounds or paper filters, discard the contents of the coffee reservoir, and clean the exterior of the machine using a damp cloth.

Step 3: Charcoal water filter

Remove the charcoal water filter from the water filter holder in the water reservoir.

Step 4: Mix and Add the Descaling Solution

Follow the manufacturer’s instructions to mix the descaling solution with clean water. Add the solution, filling the water reservoir of your coffee maker to capacity.

Step 5: Start the Cleaning Cycle

Press the “Clean” button. When the self-clean light glows, turn the coffee maker on. The “Clean” light should shine steadily, indicating that the coffee maker is now in cleaning mode. At the end of this cycle the coffee maker will beep 5 times and then  turn off. Turn the coffee maker on. If the “Clean” light is still flashing, repeat steps 2-5 with fresh cleaning solution. If the “Clean” light is not flashing, continue to step 6.

Step 6: Rinse and Repeat

Once the descaling cycle is complete, discard the descaling solution in the coffee reservoir. Rinse the water reservoir thoroughly and refill it with clean water. Run a cycle with fresh water only. Discard this from the coffee reservoir. Repeat this step twice to ensure thorough rinsing.

Step 7: Final Rinse and Reassembly

After the final rinse cycle, empty the water and coffee reservoirs and replace the charcoal water filter. Your Cuisinart Coffee On Demand coffee maker is now descaled and ready for brewing. Reassemble all components and enjoy your fresh and clean coffee.

Tips for Maintaining Water Quality and Preventing Scale Buildup

Regular Cleaning

In addition to descaling, regular cleaning of your Cuisinart Coffee On Demand coffee maker is important. Clean the removable parts, such as the water reservoir and the coffee dispenser, after each use to remove any coffee residue and prevent the buildup of oils and minerals.

Filtered Water

Using filtered water can help ensure the best tasting coffee. Consider using filtered water to ensure the water you use in your coffee maker is of the highest quality. Note: the Cuisinart Coffee On Demand coffee maker does include a charcoal water filter that will remove some chlorine, tastes, and odors from your tap water, however, these are not certified by NSF or ANSI for safety and effectiveness so you’re better off using your own water filter that has been certified by NSF or ANSI. That said, if you do use the Cuisinart charcoal water filter in your coffee maker, they do recommend replacing it about every 60 days or every 60 uses.

Avoid Harsh Cleaners

When cleaning the exterior of your coffee maker, refrain from using abrasive materials that can damage the surface. Instead, use a soft, damp cloth and mild soap to wipe away any dirt or stains.


Regular descaling is essential for maintaining optimal water quality and prolonging the life of your Cuisinart Coffee On Demand coffee maker. By following the simple steps outlined in this article and implementing preventive measures, such as using filtered water and regular cleaning, you can enjoy a delicious and flavorful cup of coffee every time.

Remember, a well-maintained coffee maker ensures that the flavors and aromas of your coffee are not compromised by limescale buildup. Take the time to descale your Cuisinart Coffee On Demand coffee maker regularly, and savor the rich and satisfying coffee it brews. With proper care, your coffee maker will continue to provide you with the perfect cup of coffee for years to come.


How often should I descale my Cuisinart Coffee On Demand coffee maker? 

The frequency of descaling depends on the hardness of your water and the frequency of use. As a general guideline, it is recommended to descale your coffee maker every 2-3 months. However, if you notice a decrease in performance or an alteration in the taste of your coffee, it may be an indication that descaling is needed sooner. Your Cuisinart Coffee On Demand coffee maker’s “Clean” light will also flash when it detects mineral deposits on the sensors.

Can I use vinegar as a descaling solution for my Cuisinart Coffee On Demand coffee maker?

Yes, you may use distilled white vinegar, but per manufacturer instructions, it should be diluted to 1 part vinegar and 2 parts water. 

Is descaling necessary if I have a water softener installed? 

Even if you have a water softener installed, descaling is still necessary. Water softeners reduce the hardness of water by removing minerals, but they do not eliminate them entirely. Descaling helps remove any residual mineral deposits that may have accumulated over time, ensuring the continued performance and longevity of your coffee maker. That said, if you have moderately to severely hard water, you may benefit from installing a water softener in your home.
