Why Does My Blender Smell Like Vomit ?

 A blender is a piece of kitchenware used primarily to grind grains or other dried nuts into a powder or to shred recipes into smaller bits for the preparation of soups and lots of other delicacies. Notably however, there are different kinds of blenders for different purposes, since those used for grinding may not necessarily be used for processing liquid foods and so on.

Why does my blender smell like vomit? Blenders usually smell when their bearing assemblies become seized from liquids and food seeping through. This seeping of food substances is known to task the motor to work even harder than it ordinarily should, and consequently overheat in the process or become burnt out.

“It is this burning that causes the vomit odour”.  In addition, the failure of other parts in your blender can cause the motor to fail too, resulting in a burning or electrical smell. When the blender blades do not work or rotate freely, it causes added friction and overheating the electric motor, which can manifest as an irritating smell, sometimes associated with even smoke.

What can cause a blender jar to smell badly?


 First and foremost, a blender can smell badly if its electric motor is overheated and hence gives out a choking odour similar to the smell of burning electric components.

When these foods particles seep through such openings, they overwork the electric motor, which elicits the burning odour. They can also smell from stuck-on food debris or improper washing with the correct cleaning agents.

As for the blades, if you wish, you can unmount them and wash them manually with soap or insert them into the dishwater too. They are mostly metallic and are not likely to come into any harm this way. After washing, clean your blender of any traces of water thoroughly, which will ”prevent metallic rust”.

Most importantly, if you are not sure about anything in terms of cleaning your blender, always consult your accompanying user manual or seek for advice from experts or the customer care service center of the manufacturers.
