Ninja Coffee Bar clean light keeps coming on(3 solutions)

Does it happen that your Ninja coffee bar clean light keeps coming on? This is a very common problem. Sometimes the light will not go off – even when you have just cleaned the machine! It can be a huge pain in the neck!.

A lot of Ninja Coffee Bar buyers report this problem. I got the idea for writing this guide when someone got in touch with me saying:

“My clean light stays on all the time even when I just cleaned it. And this gives me headaches! I even don’t know whether the Ninja Bar is actually clean or not and if it’s safe to drink coffee from it. Please help!”

In this post we will look whether this light not switching off is a circuit board issue, a programming error, or just needs some basic troubleshooting.

The clean light is a common problem in some Ninja models and needs a slightly technical fix. We have discussed three troubleshooting methods below which will help you in your coffee bar light issues.

Troubleshooting Method 1: incomplete cleaning

Generally most of the Ninja Coffee Bar issues relate to cleaning. And the issue of the Ninja Coffee Bar clean light keeps coming on may be related to irregular cycles of cleaning or if you are descaling the machine after an extended period of time.

The science is simple. The “clean light” button on Ninja Coffee Bars lights up when the machine senses calcium and other mineral deposits, and it is an alarm for you to descale the machine.

Now if you do not clean the machine regularly and clean it after a lot of accumulation of sediments, then even after your descaling process the machine continues to sense the debris.

The descaling process was not able to completely clean the Coffee Bar and it probably needs one (or more) extra descaling cycle.

So if the Ninja Coffee bar’s clean light keeps coming on, try to descale it twice, or even three more times. The moment you will descale again the light should turn off.

Troubleshooting Method 2: pressing the wrong buttons

The second common mistake that keeps the light on after a clean up is not pressing the needed buttons, or pressing extra buttons. Below is a step by step process that you can follow to avoid the issue.

  • After the whole process of descaling the coffee bar, there will be a sign flashing “Flush” on the clock timer screen.
  • Fill the reservoir again, and this time do not use any descaling solution. Just regular water will do.
  • Tap the “Clean” Button – and do not press and hold. A simple tap will start the flushing process.
  • Remember, DO NOT ACTIVATE ANY OF THE BREW CYCLES TO FLUSH.
  • The machine will start flushing the water; it will not start the whole clean cycle.
  • After the flush the clean button should go OFF.
  • If you press the brew cycle buttons while flushing the second time the light will not go off. And this will happen even if you do the full descaling process twice or many times.

Note: Attempt this solution only if the first troubleshooting method does not work. There is a high chance that the first method itself will solve your issue.

Troubleshooting Method 3: restarting the machine

As in most of the electrical devices – a simple restart is the solution to most of the problems. If the light in your Ninja Coffee Bar is not switching off even after both the troubleshooting methods, then a restart of the machine might help.

Sometimes the cleaning process is not the problem. In fact the problem lies in electrical components which result in light errors like these.

An unwanted static current accumulation in the switch or adapter or any of the electrical parts will not allow the light to go “OFF”. When you reboot the machine or switch it off completely, all the electrical charge goes away. This eliminates chances of static current accumulation.

A fresh start of the machine will solve your light issue.

Note: Remove all the wires from the socket when you turn it off to properly restart the machine. Just switching off the machine will not help all the static current to drain if it is still connected to the mains.

I’d like to point out that you should try troubleshooting method number 3 in the very last – because generally light issues are due to cleaning errors. Ninja Coffee Bars are highly sophisticated machines and issues like these (electrical problems) are not commonly reported in these coffee makers.

Frequently asked questions

What happens if you don’t descale your coffee machine?

If you don’t descale your coffee machine every so often(2-3 months), limescale will start to build up in the internal pipes. That will make your coffee taste weird and eventually it can reduce the efficiency of your machine.
Not descaling can also lead to a buildup of bacteria which can cause health issues.

How long does the clean cycle take on the Ninja Coffee Bar?

A clean cycle is essentially just running a brew cycle with descaling solution instead of water. For best results, you should let the solution sit inside the pipes to give the acid time to react with the scale. In total, you’re looking at 30 minutes to an hour including the rest time.
