Blendtec Blender Problems: 7 Common Issues (Simple Fixes)

Here are 7 common issues with Blendtec blenders, along with effective ways to help you fix them.

This is not to say that if you buy a Blendtec, you will have these problems.

These are the most commonly experienced problems.

Not too dissimilar to other fridge brands.

Blendtec Blender Not Turning On

At times you might not be able to turn on your Blendtec blender by simply pressing the start button.

Blendtec blender not turning on is typically caused by a faulty power supply or fuse. 

In such a situation, it’s best to follow the solutions mentioned below to start using your blender again.

Possible solution(s):

  • First off, ensure proper power connectivity to the blender by checking for loose power cables
  • If everything seems fine with power connectivity, try plugging in the blender in a different socket. If it works again on a different outlet, the problem is most likely with the original outlet.
  • Additionally, you can also check the fuse. To test the fuse, use a voltmeter and if you notice a high reading, replace the fuse to fix your blender.

If you are unsure about any of these tasks or do not want to risk voiding your appliance’s warranty, contact a qualified technician.

Blendtec Blender Leaking from Bottom

While leaks from the top can occur due to overfilling the blender jar and can easily be fixed, bottom leaks can be quite frustrating.

However, the solutions mentioned below can help you fix this issue with ease.

Possible solution(s):

  • Check the sealing ring at the bottom of the jug is correctly placed sealing the contents within the jug.
  • The most common culprit behind a Blendtec Blender is caused by a bottom leak of a broken blender jar. Detach the blender jar and check for any cracks. Even a hairline crack is enough to cause a leak.
  • However, if the jar appears to be fine, the blender gasket responsible for making a leak-proof seal might be broken. Detach the jar and replace the gasket if it’s broken.

Blendtec Blender Blade Not Spinning

If your Blendtec blender turns on but does not start blending, you have likely overfilled your blender. 

Refer to the solutions below to fix the issue.

Possible solution(s):

  • A common reason for this issue is that you might have overfilled your blender jar, making it difficult for the blades to spin. Try starting the blender after taking out some food.
  • If the problem persists, the fans may not be able to spin due to a lack of liquid. Add some water and then start the blender.
  • If the blender still doesn’t spin, there is a mechanical problem with the drive gear and motor. Call a professional to fix the issue.

If you are unsure about any of these tasks or do not want to risk voiding your appliance’s warranty, contact a qualified technician.

Blendtec Blender Too Slow

Over time, you may notice your Blendtec blender spinning slower than usual, which is usually caused by being overloaded with ingredients or having motor problems.

This can be a major issue, as it can make it quite difficult for your blender to chop food.

However, the solutions mentioned below can help you out of this problem.

Possible solution(s):

  • Make sure the ingredients are not overloading the blender. Too many solid ingredients will also make it difficult for the blades to move effectively.
  • The main reason behind slow blade spinning is worn-out brushes in the blade motor. To fix the issue, you will need to replace the motor.
  • However, another reason might be overfilling and a lack of water which can make it harder for the blades to rotate.

If you are unsure about any of these tasks or do not want to risk voiding your appliance’s warranty, contact a qualified technician.

Blendtec Blender Produces a Burning Smell

Blenders can produce pungent smells at times.

If you notice a burning smell, it is no common occurrence and is indicative of a serious issue caused by faulty wiring. 

So, follow the solutions below to fix the problem.

Possible solution(s):

  • If there is any burning smell, switch off your blender before troubleshooting. There may be loose wires that might have short-circuited within the blender.
  • However, if you don’t have the expertise to test such wires, call in a professional to fix the problem.

Blender Still Not Working?

If you have tried all the above-mentioned solutions to the problems, you are facing and the blender still fails to work, there may be a more technical issue.
