Cleaning your Ninja coffee maker periodically is important if you want to keep it running efficiently. Over time, hard water causes calcium to build up in the machine. To remove these calcium deposits, you can use the machine’s clean cycle function. It’s very simple. Just pour a mixture of descaling solution and water, or white vinegar and water, into the water reservoir and press the “clean” button. You should run this clean cycle as soon as the clean light on your machine turns on to keep your coffee maker working at its best.

Clean your coffee maker whenever the “clean” light illuminates. The “clean” button is located at the bottom right of your coffee maker. You’ll know it’s time to clean your unit when a thin red light appears under the word “clean.”^{[1]

- Although you’ll still be able to make a pot of coffee if the clean light is on, you’ll still want to clean your unit as soon as possible.^{[2]

Pour descaling solution and water into the reservoir up to the “Max Fill” line. Descaling solution helps remove calcium buildup from your machine, which can improve its performance and the flavor of your coffee. Look at the directions on the specific bottle of descaling solution you’re using to find out exactly how much solution to use.^{[3]

Use white vinegar instead of descaling solution to save money. White vinegar works just as well as descaling solution and is also cheaper.^{[4]

- Use only white vinegar. Other types of vinegar—such as rice vinegar, balsamic vinegar, or black vinegar—won’t work.
- The travel mug line is the second line from the bottom on your water reservoir.
- Be careful never to fill your reservoir above the Max Fill line.^{[7]

1
Empty the carafe once the clean cycle ends. When the clean cycle ends, the light next to the clock display will flash, and the word “Flush” will appear on the display. To empty the carafe, simply pour the liquid into your sink.^{[10]

- The liquid in the carafe will be hot, just like freshly-brewed coffee, so be careful when pouring it out.
2
Refill the reservoir with tap water and press the “clean” button again. Once you’ve poured the liquid out of your carafe, put the carafe back under the brew basket. Then, fill the reservoir up to the “Max Fill” line with water.^{[11]

- This first flush will take around 8 minutes.
- You don’t need to add descaling solution or white vinegar for this step.
Once the clean cycle with water finishes, dump out the water, and repeat the flushing process. These flushing cycles will help clear the descaling solution, or white vinegar, out of your machine, keeping your next pot of coffee fresh and tasty.^{[12]

Expert Answer

Fill up the coffee maker's reservoir with white vinegar and run it through your machine. After that, flush the system out by running another cycle with clean water.
