  1. Check Power Supply

If your blender is not blending properly, you may be experiencing a power problem. This can be due to a plug-out issue, loose connections, or a fried circuit.

In this case, you will want to check the power source by plugging the blender into an outlet and checking the breaker box to ensure it is not tripped.

  • Power Cord

One common cause of blenders not blending smoothly is a power cord kink. A frayed power cord can damage the internal wiring. To check its power cable, unplug the blender and examine the cord. Look for visible kinks in the cord.

If you find kinks, you will need to replace the cord. Alternatively, you can consult the owner’s manual to determine the proper replacement method. You can test the cord’s continuity by putting a multimeter probe on both the male and female ends.

If the cord is still functioning, you should see a reading of 0 ohms. If the number fluctuates, you’ll need to get a new cord.

  • Outlet

To check if the power supply of your Ninja Blender is functioning properly, make sure that you have plugged it into a functional power outlet.

  • Insufficient Current Supply

Another possible cause of Ninja Blender not Blending smoothly is a lack of current. Before attempting to resolve this issue, you should first ensure that there is nothing wrong with the power supply.

Try using other kitchen appliances, such as a coffee maker, to test the power supply. A multimeter can help you test a power outlet for continuity. It will show you the voltage if it has power flowing through it.

Plug the tester into the correct slot of the outlet and watch the display. If the multimeter shows continuity, the outlet is functioning properly.

If you are unsure about how to test a power outlet, it is best to contact a licensed electrician. Generally, a multimeter will have a range of voltage from 120 to 240 volts.

  1. Inspect the Multispeed Switch

If you notice your blender is not blending smoothly, it might be time to inspect its multispeed switch. The switch is responsible for sending current to the motor, so the higher the current, the faster the motor will spin.

This component is very important and can malfunction at any time. It should be cleaned or replaced when necessary. If your blender is not blending smoothly, it could be due to a problem with its multispeed switch.

The switch is usually exposed on the front of the blender. It should be replaced if the inner wires are damaged or twisted. If the multispeed switch isn’t working, you should check your kitchen circuit breaker to ensure the appliance isn’t damaged.

You can also check your fuse with a multimeter. If blown, the electric current will not flow to the blender.

  1. Stuck Assembly

If the blades of your blender are not spinning smoothly, the blade assembly may have become stuck. If this is the case, you can fix the problem by ensuring the base is tightly screwed.

You can also remove chunks of food from the container to help the blades spin. If this problem persists, you should consider having the blender serviced.

  1. Service the Blades

If you are experiencing this problem, you may need to service the blades. The first step is checking the blade assembly and base to ensure they are tight. If they are loose, check the gasket and replace it if necessary.

The blades are not sold separately in hardware stores, but you can easily get them from a Ninja blender supplier. They are typically backed by a robust warranty and can be repaired yourself or by a qualified repair person.

In many cases, the blade assembly must be replaced if the blender isn’t blending smoothly. The blades are a sensitive part of your blender. They can cause problems if not properly serviced.

If you are unsure about the proper way to sharpen these blades, you can consult your owner’s manual or contact the Ninja customer support center.

  • Cleaning the Blades

The blades of your Ninja blender may be dirty or clogged, preventing the blender from making a smooth blend. To fix this issue, empty the unit and unplug it. Then, make a solution of soapy water and get a sponge to clean the blades.

Make sure you clean everything and that you don’t overload the blender. If you still find your Ninja Blender is not Blending smoothly, you might need to replace the blades.

These can be replaced easily and quickly. If that does not solve your problem, consider contacting an electrician.

  1. Service the Motor

If you notice your Ninja Blender is not blending properly, it may be time to service the motor. This easy fix will likely restore your blender’s original functionality. First, turn off the blender, and then look for any signs of damage. See if you have a jam in the base.

If so, remove the jar and inspect the motor. If it appears damaged, call a qualified electrician to service it. Although the motors in blenders can withstand a lot of use, they can get damaged after several years.

You can easily check if the motor is damaged by applying a resistance probe to each prong of the cord.

  1. Correct Ingredients Order

Ensure that the liquids are at the beginning of your recipe. You allow the blender to do its magic by starting with liquids first.

As the blades spin, they form a vortex that sucks up the harder ingredients. For instance, you should add protein powder and peanut butter after the liquid.

In addition to that, start the blender low and gradually increase the speed until the desired consistency is achieved. Moreover, it’s better to add powdered ingredients last so they will be fully incorporated into the blend.

  1. Clean the Blender

Keeping your Ninja Blender clean is important, and there are several ways to do this. First, it is important to wipe off all the food residues on your blender.

These substances can collect in crevices, cementing the blender’s base to the jar and promoting bacterial growth. Using a dish brush to remove this residue can help. You can also apply a paste made of baking soda to remove any remaining stains.

  • Self-Cleaning

Alternatively, you can use the self-cleaning function of your Ninja blender. This function is available on many models, and you must pour some warm water and dish soap into the jar.

The Ninja blender will blend the warm water and soap, removing any remaining residue. Once the process is finished, rinse your blender with clean water and allow it to dry. You can also hand wash the jar if you want to be more thorough.

This method is more effective for removing dried-out food residues. The blade assembly is a common part that becomes soiled with food and debris.

If you have difficulty getting rid of stains on your Ninja blender, try rinsing the blade unit with soap after every use. If you are unsure how to properly clean the jar, read the manual carefully.

  • Lemon Juice

Also, lemon juice can get into crevices, cementing your blender base to the jar and encouraging bacteria to grow. Lastly, the Ninja Blender can also be cleaned with a damp cloth. It’s best to wipe it dry before reassembling it.

And yes, you should never put the jar in the dishwasher. Keeping your blender clean will help keep it in good shape for a long time.
