Reasons Why Your Vitamix Overheats

Whether new or old, you may experience the burning smell from your valuable Vitamix blender just when you think you are about done preparing your smoothie.

Here are the reasons behind your Vitamix overheating:


Every Vitamix blender has a ‘Max Line’ indicating the maximum level you should add your ingredients. Anything above the line is overloading and could cause overheating.

Overloading your Vitamix, especially with ingredients, causes the blades to slow down when pureeing the ingredients. Consequently, the motor will start overheating.


Use the correct quantity of ingredients, consistently below the maximum line, to avoid overworking your Vitamix.

Wrong Ingredients

Additionally, using very thick ingredients such as peanut butter paste in your Vitamix in large amounts may cause pressure on the blades leading to overheating.


To prevent your Vitamix from overheating, avoid adding hard ingredients into your blender. If you are preparing thick ingredients, it is best if you make them in small batches.

Note: If you insist on using hard ingredients, use a high-powered machine such as Vitamix 5200, built with strong blades and more horsepower to handle the task.

Air Pockets

You wouldn’t try to run an empty Vitamix, would you? The blades will malfunction and cause your Vitamix to overheat. The same happens when you create air pockets with your ingredients.

Using leafy ingredients at the base of your Vitamix creates air pockets preventing the blades from normal functioning, causing your Vitamix to produce a burning smell due to overheating.


To prevent air pockets from forming, pour liquids into your Vitamix before adding the leafy ingredients such as spinach which will also create a good order of ingredients in the blender.

New Vitamix Blender

Vitamix motors and drive sockets tend to heat up the first time you use your new machine. Almost like an initiation into the labor world, right?

When you notice the burning smell with your new Vitamix, it will most likely be the windings in the base burning, which is no cause for alarm.


Allow your Vitamix to cool down for about 45 minutes when it starts to overheat before proceeding to prepare your smoothie.

If in a space with high room temperature, your Vitamix may take longer to cool down. Unplug the Vitamix from the power socket, take out the container, and blow-dry the base to cool it down.

However, if the overheating does not stop, contact the Vitamix customer care agents for assistance.

Inappropriate Running Speed

Running your blender at high speed for too long will overwork your motor, and your Vitamix will start to heat up, producing an electrical smell.

Running your blender at a very low speed, especially when handling heavy ingredients, will overwork your Vitamix as well, causing it to overheat.


Set your Vitamix to the appropriate speed setting as directed in the Vitamix manual or the cookbook manual to maximize the service length of your Vitamix.

Vitamix Blades

Most blenders, including Vitamix, have Dry grain (D) or Wet blades(W). Dry grain blades are for grinding hard grains such as peanuts. Wet blades are for blending liquids such as smoothies.

Using wet blades to puree hard grains means that the blades will run at a very slow speed on hard ingredients, which will overwork the blades causing your Vitamix to overheat.

Likewise, adding soft ingredients into dry grain blades meant to burst out nuts means that the blender will run at high speed for a smooth task causing it to overheat.


Only add liquid ingredients in the wet blades containers and hard grains in the dry grains blades to prevent your Vitamix from overheating and enhance its service life.

Additionally, the tamper helps to release air pockets that form around the blades allowing smooth flow of ingredients through the blades.

Do Vitamix Blenders Self Protect From Overheating?

Yes, Vitamix blender motors are built with an Automatic Overload Protection that prevents your Vitamix from overheating.

The Vitamix automatically switches off when the motor starts to overheat or when it starts to produce a burning smell.
