Clean Light On – Ninja 10-Cup Specialty Coffee Maker

Cleaning the coffee pot is easy

One of our readers caught me the other day and asked why the “Clean” light was on for their Ninja 10-Cup Specialty Coffee Maker. They threw the instructions out and thought I might know. I didn’t know off the top of my head, but after a bit of research, I found the answer, and lucky thing for you, these instructions will work for the CM401, CP301, and CP307 models of the Ninja Specialty Coffee Makers and Ninja Hot and Cold Brew Systems. Other models have not been confirmed yet, but most likely, if you have a clean light with a 50 oz reservoir tank, these instructions will fit perfectly.

Answer: The clean light on the brewer means it is time to clean your coffee maker. Follow the instructions below to clean the coffee maker. I gathered these instructions from the Ninja coffee maker manuals in Oct 2021.

If you do not have one of the models listed above, check out our guide to using vinegar in coffee machines here (opens in new tab).

Cleaning Ninja Specialty Coffee Maker

and Ninja Hot and Cold Brew Systems

  1. Wait for the unit to cool down and remove the filter holder from the brew basket, wash the filter with soap and warm water.
  2. Select Full Carafe size and set the empty carafe in positon like you would for a normal brew.
  3. Use the descaling solution (see our equipment guide with options opens in new tab), or use vinegar. Either way fill the reservoir with the descale solution or 16 oz of distilled vinegar.
  4. Fill the reservoir the rest of the way to the Max fill line (should be 50 oz) with distilled water.
  5. Press the CLEAN button
  6. The Ninja will take over the cleaning process and it will take approximatley 60 minutes to complete the process.
  7. When finished you will hear a beep and the CLEAN light will turn off.
  8. Empty and thoroughly clean the carafe and water reservoir with warm, soapy water to remove any cleaning solution or vinegar.
  9. Fill the reservoir with water to the Max Fill line and put the empty carafe in place like you normally would for a brew.
  10. Now flush the system by running a full Carafe, Classic Brew cycle with the water only. After completion, discard the water and clean the carafe again.
  11. Repeat steps 9 and 10 if you smell any vinegar or cleaning solution smells in the coffee maker,; but, typically 2 flushes will completely eliminate the smell for the most sensitive noses.
  12. If the CLEAN light comes on again, calcium build-up is still present in the machine. Start back at step 3 and repeat.

Quick Notes on Cleaning Other Parts of the Ninja

  • The carafe is not dishwasher safe. You should only use a soft brush or foam brush and mild soap with warm water to clean it.
  • The reservoir is top rack dishwasher safe feel free to clean this after your first treatment (handwash instructions are similar to the carafe, warm water, mild soap, soft brush).
  • The brew-through lid from your Ninja coffee maker is top rack dishwasher safe.
  • The coffee and tea permanent filters are top rack dishwasher safe.
  • The flip-top lid is top rack dishwasher safe

Enjoy a job well done

I checked all of the manuals and did some further digging, and added a bit from my personal experience with coffee brewers and past research for this article.; we do not have one of these yet, but I’m actively researching to purchase one.
