The Best Way To Descale Cuisinart Coffee Makers

The water used to brew your coffee has minerals that build up inside your Cuisinart. These are not toxic but they can impact the flow, temperature and performance of your brewer. They can affect the taste of your cup of coffee too. Descaling is the deep clean process that removes those minerals and can help extend the life of your Cuisinart coffee maker. Keep reading to learn how to clean and descale a Cuisinart coffee maker and how to reset the clean light if it won’t turn off.

How To Clean Cuisinart Coffee Maker On A Daily Basis

You should do regular basic cleaning for your Cuisinart the same way you would clean any other drip coffee maker and coffee pot. Ideally at the end of each day you would clean the filter area, the coffee pot and wipe down the exterior of the unit. If you don’t want to do this daily, I would suggest you do it weekly. Don’t let it go longer than that.

Lift the coffee maker reservoir cover. Remove and discard the paper filter. Wipe the area under the filter basket with a damp cloth. Wash the filter basket in warm, soapy water and rinse well. You can also wash it in the top rack of the dishwasher. Dry it fully before returning it to the brewer.

Remove the carafe from the heating plate. Empty any coffee inside. You can wash the coffee pot and lid either by hand with warm, soapy water or in the top rack of the dishwasher. If washing by hand, be sure to only use a soft sponge or brush. You never want to use stainless steel wool or other abrasive cleaning tools because they can scratch the pot.

To clean the base and the heater plate, wipe them with a clean, damp cloth. If there are fingerprints or other blemishes you want to remove, try using warm soapy water.

How Often To Descale A Cuisinart Coffee Maker

Cuisinart says that you should descale your coffee maker every 3 to 6 months. If your coffee maker starts making unusual noises, or if your coffee starts to taste bitter, it’s a sign that you need to descale. Regular deep cleaning is needed whether you are using filtered, bottled or tap water with a low to normal mineral count. If your tap has “hard water,” meaning it contains higher level of minerals, then you should deep clean your brewer more often. If you are not sure about the mineral content of your water, you can get a low-cost water testing kit.

The Cuisinart Coffee Maker Clean Light Button

Some Cuisinart coffee maker models, including the SS10, will have a DESCALE message on your display. Other Cuisinart coffee maker models will have a CLEAN light. These alerts will be triggered by sensors that detect that mineral buildup is interfering with performance. When you see this warning you should descale as soon as possible. Even though you can still make coffee, ignoring this will ultimately damage your brewer.

Descaling Solutions

The best way to clean your coffee maker is with one of these solutions. They contain safe and effective types of cleansing acids that won’t damage your machine.

Impresa Coffee Machine Descaler

The Essential Values cleaning solution contains a concentrated citric acid that is both odorless and powerful. Each bottle is good for two uses. A two pack will provide four doses. That’s a year supply if you clean every three months. 

Can You Clean A Cuisinart Coffee Maker With Vinegar?

If you look at your user manual, you will likely see that Cuisinart’s descaling instructions include steps on how to prepare a cleaning solution with vinegar. Most coffee machine manufacturers do not recommend this. That’s because vinegar contains harsh acids that can wear down metal components inside the unit. This can eventually cause leaks. Vinegar is also not as effective as commercial solutions in removing coffee residue and oils. It can also leave a lingering odor and affect the taste of your coffee.

That said, if you are comfortable using vinegar then go ahead and do it. You can still follow the same steps below. To prepare the solution fill the water tank with 1/3 white vinegar and 2/3 fresh water. You may have to run the rinse cycle a few extra times until the vinegar smell is gone.

How To Reset Cuisinart Clean Light or Descale Light If It Won’t Turn Off

If the clean light blinking is still on after you have run a descaling cycle and it won’t turn off, there are a couple things you can try to reset the clean light:

  • Turn the machine off. Unplug it from the power outlet. Let it sit for 15 minutes before plugging it in and turning it on again. There is no reset button on your Cuisinart coffee maker so this is the only way to attempt to do this.
  • If you have a Cuisinart SS model like the SS10 or SS15, place a cup under the single serve outlet. Next, press the 6 oz and 8 oz buttons at the same time. This should run some water through the Cuisinart coffee maker and reset the clean light.

If you’ve had your Cuisinart coffee maker for more than 3 or 6 months and have never descaled or if you have hard water, a clean light that won’t turn off could also mean there is more mineral buildup remaining that needs to be cleared. You should repeat the process once or twice more using new descaling solution. If the clean button continues to stay on, then you should contact the Cuisinart Consumer Service Center at 1-800-726-0190.
