Keeping your Ninja CM401 Specialty 10-Cup Coffee Maker clean and descaled is key to enjoying great-tasting coffee. Here's how to do it:
Cleaning:
Descaling: 6. Select the Full Carafe size and place the empty carafe under the brew basket. 7. Fill the water reservoir to the Max Fill line (50 oz.) with a coffee maker descaling solution. Follow the solution's instructions. 8. Press the CLEAN button. 9. The clock will count down the 60-minute cleaning cycle. The machine will pause periodically to maximize cleaning. 10. The coffee maker will beep, display "End," and the CLEAN light will turn off when complete. 11. Empty and thoroughly clean the carafe and water reservoir with warm, soapy water to remove any cleaning solution. 12. Fill the reservoir with fresh water to the Max Fill line, place the empty carafe, and run a Full Carafe, Classic brew cycle with water only to flush the system. Discard the water and clean the carafe.
If the CLEAN light comes on again, repeat the descaling steps. The light will turn off when the coffee maker is clean.
