Ninja Coffee Bar Clean Light Won’t Turn Off? (4 Reasons It Stays On) 

Cycle Reminder

If you’ve not cleaned your coffee bar in a while, the light staying on is an indication it’s time to clean. You will need to run a full cleaning cycle - with descaling solution or white vinegar. Pour the solution into the water reservoir and fill it with water. Place the carafe underneath and press the clean button once. This will run the full cycle and should take 60 minutes. Make sure to flush the coffee bar afterward.  

Debris Build-Up

If you’ve run the cleaning cycle and it’s still staying on, there could’ve been a big buildup of dirt and minerals in the machine. It could also be the basket and water reservoir need cleaning too. You will need to flush the machine after cleaning, which is done by filling the reservoir to the brim and pressing clean again. Make sure to wash the basket after a clean cycle to remove any remaining debris after the cycle.  

Incomplete Cycle

If you don't finish the cleaning cycle, then the light will stay on. You will need to run the entire cycle, including the descaling, flushing, and cleaning of the carafe, basket, and reservoir. If they are particularly dirty, they may need soaking and a good scrub.  

Pressing Wrong Buttons 

If you press the wrong buttons during a clean cycle, the machine won’t register the clean cycle as complete. When directed to flush the system, don’t press any of the brew cycles. This won’t finish the cycle, and the light will stay on. Make sure you press the clean button once directed, which will start the flushing process. After doing so, the light should go off.

How To Fix A Ninja Coffee Bar Clean Light That Stays on? (DIY Steps) 

Follow these tips to descale your Ninja Coffee Bar using the cleaning cycle: 

  • Step 1:
    Pour in the descaling solution as directed by the label. White vinegar will work too. Fill the rest of the reservoir with water. 
  • Step 2:
    Press the clean button once and allow the cleaning cycle to run. Make sure the carafe is in position. The dirty water will flow into it. 
  • Step 3:
    Remove the carafe and pour away the dirty water. Take out the basket and filter and clean. Put the machine back together and fill the reservoir with water. 
  • Step 4:
    The display should read ‘flush.’ Press the clean button once more and allow the water to empty from the reservoir. Once this has finished, the clean light should go off. 

If the light still doesn’t go off, follow this very simple guide to reset your coffee maker: 

  • Step 1:
    Unplug your Ninja coffee bar and wait 5 minutes.
  • Step 2:
    Plug the bar back in and reset the clock. The indicator should have turned off in the reset. You will need to set the brew timer again as it’ll have turned off during the reset.

You may need to check inside the components to see if there's still any mineral buildup. Look inside the water reservoir for any chalky or white buildup on the sides. Then, check inside the basket or carafe for the same. There could also be buildup in the tubes or connections, which will also cause a clog or bad-tasting coffee.  

If the connections are clogged, you will need to purchase some specialty brushes that will fit inside them to scrub away the buildup. You can find some on Amazon. Make sure you use a descaling solution when you are deep cleaning the connections.  

If all of these steps above don’t work, you may need to contact Ninja directly. Check your warranty to see if it’s still in date. They’ll offer a 1-year warranty, so check if you’re still covered. Register your device on the Ninja website if you haven’t already, and submit a claim online.
