why is my ninja blender leaking?
There are many reasons why your Ninja blender is leaking. We hope that the reason for your blender leak is repairable and fixable.
Because as far as we have researched the causes of leaky Ninja blenders we have found that most of the time this leaking is caused due to cracks in the pitcher.
Again, this is not the only reason and there are other smaller issues with very easy fixes and solutions that could be leaking your Ninja blender. We have listed these reasons below.
what causes ninja blender to leak?
The most simple and easy-to-fix reason for a Ninja blender leaking is overfill. When you put ingredients and liquids beyond the MAX LINE and start running the blender the chaos in the pitcher due to the hi-speed blades pushing the ingredients above.
While the Lid on a Ninja blender is fixed, there is still a chance that some liquid may overflow out of the pitcher which will then leak down on the outside of the container.
This is not even a problem, next time you have to fill no more than a 3rd quarter of the Ninja blender pitcher to avoid overflow (if there was any).
Also, the leakage due to overfilling can be identified easily by looking around the lid and finding any traces of liquids.
Rubber Gasket under the Pitcher
In almost every Ninja blender model including the NutriNinja and the Smoothie bowl. There is a rubber seal and gasket under the pitcher.
In models where you have to detach the blade assembly such as the bullet models of Ninja blenders, these gaskets sometimes misalign from the assembly. This misalignment causes wears on the rubber and thus damages the rubber gasket.
The damaged gasket then allow some liquid and blended ingredients to leak through the bottom of pitchers or blending cups of the Ninja blenders.
If you are not seeing any apparent reason for leakage this might be the problem. Try to open up the blade assembly and check the rubber gasket to see if it is damaged. Replace it with a new one to stop leaking.
Ninja has been doing its R&D to develop efficient gaskets that could keep the blender from leaking.
For the last few years, many users are having this issue. They keep complaining to the Ninja manufacturer about the cracks in the pitcher and cups of Nutri Ninja blenders.
The cracks in the pitcher initially seem like minor scratches but within the course of less than one year, they start to leak really bad.
The problem with this cause of leaking is that it is beyond repair. You have to replace the pitcher with a new one, which will cost you a lot.
Many users are really frustrated that they think they won’t get a Ninja ever again. The customer service also seems to be not very supportive and has no solid plan on getting any long-lasting solution.
Ninja blender leaking black liquid
After a few months of blending the gasket rubber at the bottom of the Ninja blender pitcher may wear out and the dark pieces from its tearing can mix with the ingredients to make black liquid. The tearing apart of the gasket also causes leaking. So the black liquid comes out of the bottom of the Ninja blender.
Ninja blender leaking brown liquid
There are many hollow parts in the Ninja blender such as the handle that deposits residue from blending ingredients and blended products.
These moulds sometimes mix with liquids and if there are any issues with the container that may cause leakage.
The mixture of these residues and other liquids from the pitcher leak in the form of brown liquid.
This can be avoided if you are properly clean and maintain your Ninja blender after every use (Ideally).
ninja blender leaking oil
Ninja blenders with fixed blades at the bottom such as Ninja Chef or the bullet models such as Nutri Ninja or Ninja personal blenders have bearing rings. These bearings have oil to reduce friction and wear and tear of the moving parts.
With time, the constantly moving components start to degrade and the oil inside may leak out from these components. Ninja blenders with stacked blade assembly may not encounter such issues.
ninja blender blade leaking
As mentioned, the Nutri Ninja, Ninja Fit or Ninja personal blender has blades with bearings.
With time these blade assemblies start to wobble due to damage to the washers inside.
The wobbling of blades is due to the gaps in the inside components of the blade assembly and may result in leaking from the bottom of the Ninja blender.
how to fix leaking ninja blender
Few Ninja blender leaking issues are solvable while others are beyond fixation.
Leaking problems that can be fixed
If leakage is caused by overfill, you can fix it by putting a lesser amount of ingredients.
If the leakage is due to a gasket, you can replace or fix the existing gasket rubber at the bottom of the pitcher to stop leaking.
If the blades are leaking you can change the blade assembly or the bearing or the washers inside and there will be no more leaks.
Leaking Problems that are beyond repair
Cracks in pitchers cannot be repaired. Ninja blender leaking due to cracked pitcher is irreparable. There is only one solution to this problem. Replace the pitcher or get a new one.
The 1-year warranty may not cover the “normal wear and tear” of the Ninja blender pitcher in which case you need to buy a new Ninja blender container to fix the leakage problem.
