For a long time, the smoothie blender has become a familiar home appliance in the kitchen, helping you create refreshing, delicious, and nutritious smoothies, relieving the heat of summer. However, during use, the blender may encounter various issues, causing inconvenience for users. Therefore, let's explore common problems with the smoothie blender at Mytour Supermarket and quickly troubleshoot if any of the following situations occur.
1. Smoothie blender not operating or shutting down while in use
One of the common issues with a smoothie blender is that it doesn't work even when turned on or shuts down while in use. The typical cause is a power source failure, power outage, loose cord, or a faulty machine. If the issue is due to a loose cord, simply reconnect it and continue to use. In case of a power failure, it's advisable to call an electrician to fix the power network before turning on the smoothie blender. If the issue persists, indicating a malfunction, it's best to take it to the warranty center for timely assistance.

Troubleshooting Smoothie Blender Not Operating or Automatically Turning Off.
Another factor leading to the smoothie blender not operating or shutting down during use may be food stuck in the blade. To address this issue, simply turn off the blender and remove the trapped food. To avoid this problem in the future, it's best to chop food into small pieces before putting it into the blender.
The smoothie blender may operate beyond its capacity, leading to automatic shutdown or abnormal heating during use. Therefore, it's advisable to stop the machine for about 10 – 15 minutes to let it cool down before continuing to use. Avoid using the blender for extended periods to prevent excessive heat that could damage the motor.
2. The motor runs well, but the blade does not rotate
To effectively blend food, a smoothie blender requires a transmission gear set from the motor to the blade, enabling the blade to function. If this gear is worn, broken, or jammed, it can prevent the blade from rotating even though the machine operates normally. The simple solution is to replace the worn-out gear set.

3. Smoothie blender emits a burning smell while running
Typically, smoothie blenders operate at high speeds and have high power (with speeds ranging from 2000 – 8000 revolutions per minute, power: from 500W – 1000W). Therefore, when turning on the machine, ensure it runs for no more than 30 seconds to maintain smooth motor operation. Operating at excessively high power for extended periods can result in a burning smell in the following cases:
Case 1: The burnt smell around the machine body is due to the overloaded operation of the motor or the motor being clogged with dirt.
Case 2: If the burnt smell is coming from the outside of the machine body, it could be due to the blade being jammed or the rotating shaft of the blade drying up.
Case 3: The machine emits a burnt smell possibly due to a circuit malfunction or the power cord leaking plastic.
Troubleshooting:
- Regularly clean the motor to prevent it from accumulating dust.
- Add oil to the motor to enhance its performance.

4. Unable to adjust the smoothie blender's switch
After prolonged use, the switch of the grinder may encounter issues such as short circuits, jams, button sticking, or oxidation. These problems can cause the contact points of the grinder's buttons to wear out, sticking together, making it difficult for you to control and switch modes.

In such cases, you can remove the button component for inspection and resolution. Additionally, to minimize this issue, ensure that water doesn't drip onto the buttons when using the blender, as over time, it can seep into the buttons, causing shorts and button sticking. Furthermore, if conditions permit, opt for smoothie blenders with touch buttons instead of push buttons.
5. Blender not smooth or takes a long time to blend
A common issue is the blender taking a long time or not blending food well. This can be due to checking the installed blades; they may not be suitable for the type of food being blended. It's best to use blades specifically designed for the food being processed. If the blades are worn or damaged, preventing efficient blending, consider replacing them with new ones.

Blending various types of food together can also lead to uneven blending. To address this, blend one type of food or fruit at a time. Alternatively, choose blades made of high-quality, durable materials, such as those found in reputable blender brands like Smartcook or Elmich.
