Why is my Nutribullet blinking? [Troubleshooting Guide]

Last Updated on August 24, 2022 by

Our Nutribullet blenders are known to be rugged, sturdy, and durable. However, they end up developing operational issues that have us going ballistic. One of the operational challenges we have gotten asked about a couple of times is – “Why is my Nutribullet blinking?”

The Nutribullent blender has an amazing reputation for being a high-performance blender brand. So, whenever your blender starts blinking, the answer is simple; it is caused by blender overheating. Overheating occurs when the blender is in operation for a long duration without a pause or stop. It can also be caused by functioning in an environment above standard room temperature. Our electrical devices are designed to function at certain temperatures above, which results in overheating and may cause damage to the electric motor of the blender.

Why is my Nutribullet blinking?

The Nutribullet blinking is a safety feature of the Nutribullet blender that is meant to alert the user of an impending danger caused by overheating. When you notice the blender blinking instead of normal lights operation, you should quickly unplug the blender cord from the power source and allow it cool for a minimum of five minutes before reconnecting to the power source.

One way to prevent future occurrences of Nutribullet blinking is to ensure the blender is operated in a well-ventilated environment. Also, if you are blending large quantities of ingredients, try batch blending to let your blender get ample rest after each blend.

If your Nutribullet blender is overheating, you must stop its use immediately, as it may cause a fire hazard.

Factors responsible for Nutribullet Blinking and overheating

  1. Overworked motor
  2. Damaged coupler
  3. Worn seal
  4. Overloaded blades
  5. Broken brushes

Several opinions may come to your mind when you notice your blinking blender. Do you have to buy a new one, is it fixable? Will this issue keep reoccurring? To ease your worries and get all the essential Nutribullet blender facts to enable you to get past this challenge, follow on, and read this article to the end.

Causes of Nutribullet Overheating

Like many blending machines, the Nutribullet has several moving parts which enable it to perform optimally. Damage to any of these parts will prevent the proper functioning of the Nutribullet blender. Listed below are some of the components of the Nutribullet blender that will be responsible for the blender’s overheating.

  1. Overworked Motor

The Nutribullet blender’s motor is the fall guy for all the challenges faced by the blender. The functioning stress is passed on to the motor if other parts are worn or broken. While bearing the stress passed on to it from the faulty parts, the motor is then overworked. An overworked motor results in overheating. When the problem persists for a long period, the Nutribullet blender motor becomes broken. Replacing components of the Nutribullet blender at the point where the motor is overworked and damaged no longer solves the problem.

It is advisable to replace the Nutribullet blender at this point. But users can attempt to find a reputable technician to troubleshoot the Nutribullet blender in an attempt to make repairs. However, purchasing a new blender will be an effectively cheaper option.

  1. Damaged Coupler

The blender’s couplers are designed to help lock the jar to the base before blending. It is an important blender part, positioned at the top of its base. The couplers are made from rubber or plastic and can easily be damaged or worn out due to use. The coupler is designed as a fail-safe component of the Nutribullet blender, expected to stop functioning when the blades or motor of the blender are overloaded. They can warp, crack, become hard, or in extreme cases, melt.

Replacing a damaged coupler is easy. One would only need to gently unscrew or pop out the existing one from the Nutrbullet blender’s base, clear out any debris, and then neatly screw on or affix the new one.

  1. Worn Seal

The Nutribullet blender is designed with a seal – often regarded as a gasket, o-ring, or washer. The seal’s design protects the motor from the pitcher of the blender. They prevent liquid from the pitcher or jar from reaching the motor, thus preventing motor damage. Due to wear and tear, these seals get worn out, old, torn, and ineffective. Their wear and tear make them ineffective and unable to function as designed. Hence they would require a replacement.

Seal replacement is an easy task, simpler than most tasks performed on the Nutribullet blender. The process is similar to a blade installation procedure.

  • Ensure you purchase a similar seal to the one you are to replace.
  • Unscrew the base from the pitcher’s bottom.
  • Remove the worn-out seal.
  • Replace with the new seal.
  • Affix the blender’s pitcher, and you can use your blender as if it’s a new one.
  1. Overloaded Blades

Many blender challenges usually result from the non-functionality or wear out of the blades. Sometimes, you can use your blender and notice that the blades aren’t spinning anymore. This failure can cause damage quickly and make the blender overheat. The blade failure is also responsible for the metallic smell we usually perceive from our blenders. Some factors are responsible for this, including;

  • Overloading your blender’s jar causes a strain on the blade’s bearings and then seizes it from moving.
  • Also, the blades may be dull and, therefore, not cut through the ingredients in your pitcher.

Replacing your damaged Nutribullet blender’s blade is relatively simple to perform. The first step is to ensure you get the exact model number of your blender. Armed with your Nutribullet blender’s exact model number, you can buy a new blade that would fit in your blender directly from the manufacturer or a third party for installation. To install, follow the following steps;

  • Detach the blender from the power source.
  • Unscrew the pitcher of the Nutribullet blender from the base.
  • Remove all worn-out parts, and install the new ones.
  • Reconnect and use your blender as though it’s a new one.

The blade is positioned right above the seal, and it would be good maintenance practice to replace the seal while replacing the blade as a form of preventive maintenance.

  1. Broken Brushes

The brushes are located in the internals of the blender’s motor. They are designed to transfer electricity. The first point of call when troubleshooting the motor is the brushes. When the brushes of your Nutri bullet blender are overworked, they produce smoke and the renowned hot metallic smell – a tell-tale sign of a defective blender.

The brushes are a vital part of the motor, and the good news is that they can be replaced. On successfully tracing them by comparing the part of your blender’s motor with the operational manual, they can be removed and replaced. The item needed for this is the screwdriver. Installation is easy, and ensure they fit in a one-way position only.
