There are two common failures of electric toothbrushes
1. The electric toothbrush does not respond when the key is pressed
1. The battery is installed upside down
If the electric toothbrush you just bought does not respond when you press the open button, it may be that the battery is installed upside down. Check the positive and negative poles of the battery carefully. Generally, the area where the battery is installed will indicate the positive and negative poles of the battery.
2. The battery is dead
It may be because the electric toothbrush has not been charged for a long time. If it is a battery-powered electric toothbrush, the battery should be dead. Just remember to charge the electric toothbrush or replace the battery.
3. The rotating area is stuck
If it is because the connection between the toothbrush head and the electric toothbrush is stuck, remove the toothbrush head to see if it can rotate. If it can rotate, the rotor is stuck. Just clean the electric toothbrush.
4. The switch or internal components are damaged
If the electric toothbrush is damaged internally, it is not recommended to repair it yourself or send it to the after-sales service for repair, if you do not want to repair it, you can only buy another one.
2. The electric toothbrush lights up but doesn’t work when you press the power button
1. The electric toothbrush has insufficient power
The power of the electric toothbrush is too low to drive the work of the motor. Therefore, the indicator light of the electric toothbrush will be on and the electric toothbrush will not vibrate.
2. The brush head and the body of the electric toothbrush are stuck
In this case, the brush head is usually installed incorrectly, or a non-original brush head is used, which leads to inadequacy and jamming of the brush head and the body. It is recommended that the electric toothbrush must use the original brush head. The solution is to first pull out the brush head, and then plug it back in to see if it vibrates. The second is to purchase and adapt the brush head.
3. Water in the circuit board
The mainboard or circuit is exposed to water. As a result, the motor cannot start to work. The LED indicator is not affected, and it can still be turned on.
4. Electric toothbrush failure
Due to the relatively sophisticated design of the electric toothbrush and the combination of soft and hard, software bugs or crashes may occur. There is a situation where the light is on and there is no vibration. The reset button fixes the fault with one button, restarts, and restarts the software and the motor to the working state before leaving the factory.
In short, electric toothbrushes are more expensive. Correctly used can prolong the service life of electric toothbrushes. At the same time, it is necessary to pay more attention to daily maintenance. Don’t use components that are not compatible with electric toothbrushes in order to save money. I believe that with the continuous advancement of science and technology, the probability of failure of electric toothbrushes will become smaller and smaller, and the functions will become more and more powerful.
