Are you planning to buy a Ninja CF112 or similar coffee maker? If you do, then perhaps you will find this guide useful. We have reviewed the most common issues with the Ninja coffee brewers and offered some solutions.
Since we have not experienced the majority of these issues, most solutions were offered by our readers and other reviewers. If you need information about replacing your unit – go here.
1. Ninja Coffee Bar Clean Light Is Always Turning On
If the clean light keeps coming on, then you might need to clean your coffee maker (doh!). Like all the other coffee makers, the Ninja Coffee bar needs regular cleaning and maintenance. If it is never cleaned and always left dirty, it might stop working as intended. The cleaning of the product depends on how frequently it is used.
The most common problem our readers face here is that no matter how often they clean it – the light just keeps coming back after a few days. Does that mean you haven’t cleaned it correctly, probably not? It is likely a malfunctioning unit. So, instead of relying on the light to remind you about the cleaning cycles, you might have to find another way to keep track. Annoying, yes, but you can always chat with Ninja and ask for your money back or a replacement unit.
The coffee maker has a built-in sensor that could tell when the calcium buildup is affecting the working ability of the machine and it also affects the taste of your coffee. The best way to prevent this problem from coming up is by cleaning it once every month. You can buy a descaling kit to remove the calcium build up or make one of your own. Regular cleaning of the machine will prevent the clean light from coming on often.
2. Ninja Coffee Bar Keeps Shutting Off – Ninja Coffee Bar Stops Brewing
The ninja coffee bar could shut off in the worst situations, especially when you haven’t finished brewing your coffee. So, when it does stop, check if:
- You have chosen the right brew. You might have pressed the wrong button.
- Your coffee brewer is dirty.
- You need to restart it.
If none of this work and your brewer is relatively new (1-2 years old), contact Ninja and ask for a replacement. Check out their warranty policies here.
3. Ninja Coffee Bar Leaking Water
Leaking water is just a minor problem. If it always happens to your coffee bar, then maybe the water reservoir has too much water already in it.
The Ninja Coffee has a line that indicates the limit of the amount of water that the reservoir can handle. Surely, if you only keep the water up to that line, then you’ll have no problem filling it up just right. However, when there are still leaks, despite putting the right amount of water in the reservoir, check if you have accidentally detached the reservoir.
4. Coffee Doesn’t Taste Good Anymore
The coffee taste is affected by many factors. If you’re having coffee taste issues, check if you’re dealing with the following issues:
- Your coffee beans are no longer fresh. Remember that you can’t keep them in your cabinet forever. Those beans have a finite shelf life! Not storing those beans properly could also lead to losing tons of flavor because of oxidation and release of gases of the coffee oils. It also helps to buy the best coffee beans. Don’t settle for coffee with vague labels, when you can buy better coffee.
- You’re using tap water. If it doesn’t taste well, filter it.
5. Ninja Coffee Bar Beeps 5 Times
If instead of brewing coffee, your machine just beeps, then you have a problem. But, if it continues to do so before the coffee is done; make sure that the filter mechanism is pushed all the way in and that the ‘drip stop’ is open. The beep often means that you have to adjust the brew settings.
If the brewer beeps mid-brew, or it doesn’t start brewing at all – you can try running 2 clean cycles and checking the water valve to make sure it is not plugged.
If your Ninja brewer experiences more serious issues, you should contact the manufacturer and ask for a replacement. The aim of this post is to brainstorm some quick and simple solutions offered by our readers.

This article is rediculous. The Coffee Ninja is just a BAD product. I could clean my machine every day, following the manufacturer’s instructions, and it still shuts off mid-brew. Sometimes the “needs cleaning” light comes on 3 days after I’ve cleaned it, sometimes it just shuts off with no cleaning light coming on. I unplug it, plug it back in after a minute or 2, and the problem still doesn’t get resolved. The problem doesn’t have anything to do with how clean it is, it has to do with it being a really REALLY bad product. Check out the millions of reviews of people all having the exact same problem.
Hey P Kay,
Thank you for sharing your thoughts on the Ninja brewer.

Hope that helps!
I’m having the problem of it shutting off before brewing much coffee. I’ve cleaned it and still have problems. I haven’t had the coffee maker that long, but I feel sure I’ll need to replace it soon. Too frustrating! Why does it stop brewing before time?
I’m having an issue where my coffee machine won’t come on at all.
Great reply, Anthony. I have had my Ninja coffee maker for over three years and aside from descaling with some white vinegar and water, I have never had to do any maintenance. This coffee maker has been used twice a day for that long. It has been the best I’ve ever had. I especially appreciate that it starts by allowing the coffee to flower before the second round of brewing. I’ve recommended to others and they love theirs. All products have some shortcomings. Nothing is perfect.
I think you nailed it. It’s just a weird machine and unpredictable. It was a gift. I’ll never buy one.
I got the same problem . This is product is bad period.
Ive tried to clean my ninja coffee maker,however,it shuts off so i have to start it again, any suggestions?
Push the drip basket in firmly. Mine is working right now!
I am struggle with having to constantly “clean” every 10 days. I have tried vinegar, descaling coffee maker solution, using only deer park water, and all the other suggestions. Every 10 days like clock work the clean button comes on. This is getting frustrating and expensive after a year of doing this. Any other suggestions?
I finally fixed the leaking issue. I opened up the window of my second story house and threw it out and it died of an overdose of gravity.
just had our Ninja coffee maker for 3 months and suddenly completely lost power. it shows no lights or indicators as if it is unplugged, is there a fix for this?
It is under warranty. Contact the manufacturer for a replacement.
My ninja would not allow first setting choice AND I could not set minutes. I inplugged and two months later it worked- now it decided to have SAME issues.
I have had this coffee maker for a month and already the brew cycle is not completing. I wish someone would please give me a refund or a gift card or replacement. I can’t just go out and buy another one
2 months – broken
I cannot clean under the plastic bubble/plug in the water cannister. It is quickly accumulating mold and the plug is impossible to remove. I even remove the cannister each day and let it air dry off of the machine to help with no avail. My next step is to run each through the machine. Help, because this mold grossing me out!
Have you heard back from Ninja on this? I am having the same problem and this seems to be a health concern to me.
We are having the same issue. Have you heard anything?
My steel carafe the black stuff inside is coming off in my coffee this shouldn’t do that I’ve had a few years no problems but this is annoying
al of a sudden can not insert coffee filter into machine..
My Ninja coffee pot is leaking from the bottom, what can I do?
Mine is too. I was hoping to find an answer on here
Same problem as most on here, mine will run for 10 seconds or so and beeps 5 times before shutting off. I’ve ran vinegar through it several times but nothing. This was a Christmas present from my mother so it’s appropriately 8 months old. Very disappointed in this product.
I’ve been having the issue with the cleaning light coming on every few days and this is after running 5 or 6 cleaning cycles. Now I am starting to get the 5 beeps. It’ll do the first little brew while it lets the grounds get happy, but never does the second round to give me a full cup of coffee, just gives me the 5 beeps. I did some research and there are several YouTube videos on how to fix the 5 beep issue, I would recommend trying it, it’s not very difficult to do.
My ninja beeps three times and shuts off after just a few seconds of brewing. It doesnt matter if im making coffee or cleaning it. Do i just need to get a different brand of coffee maker or is there an easy fix for this problem?
Same problem. Frustrating.
Had it less than a year
