I have gone through 3 blade assemblies now and I have become an expert and identifying the cause and result of this one issue.
Indicators to this issue:
- Noise of machine changes from spinning to a “free spinning” sound which is significantly louder
- plastic burning smell emitted
- Chunks of plastic remain in the engine base docking area.
- Brown liquid in the base area
- If all of these are happening then the cause is that your blade was probably submerged in water at some time with heat. This has popped the seal on the bearing case and the lubricant has leaked and now the bearing is rusting and can’t handle the heat being generated from the speed of rotation.
- The test is to blend a water only smoothie and see if the water changes colour to a dirty brown, if so the bearing seal is gone and the water + rust is leeching into the smoothie.
Stop use immediately buy a new blade assembly.
Learnings:
don’t put the blade in the dishwasher - the rapid heating and cooling breaches the bearing seal.
don’t submerge or leave submerged the blade assembly
Verdict - the blade assembly is not a well constructed part considering it’s high speed use and need for bearing integrity. It is very susceptible to damage and water ingress.
That’s what I’ve found

I have a Ninja BL685 that emits an odor when mixing smoothies. How do I FIX?

I bought a brand new blender and I get the burning smell. Had the same thing with the last one. I know they sometimes smell because they are new. But that shouldn't last

So I took a gamble…I put about a half a cup of water in the cup and about a quarter of a cup of olive oil. I blended the mixture for a few seconds. The olive oil released the black gook that was inside the blade mechanism. I then rinsed the blade and dried it and blended the olive oil and water again. The olive oil completely lubricated the blade mechanism. It's no longer stiff and moves freely nor is there smoking or high pitch sound. Olive oil is water soluble so even if I get some in my smoothie it's not harmful. Moral of the story is I think there is a way to lubricate the blades without having to take them apart. Just like you would put olive oil in your baking pans to lubricate them the blade mechanism need it too.

Legendary suggestion!
I was thinking I had a motor burnout with the smell.
Your tip seems to make it quieter & NO smell.
THANK YOU!!
