There may be the following reasons and solutions:
During the after-sales service or parts supply process of washing machines, the failure of "noise when powered on but the inner drum does not rotate" is one of the most common problems reported by users. For washing machine manufacturers, maintenance service providers and core component suppliers, understanding and accurately determining the root causes of such failures will help improve maintenance efficiency, optimize spare parts inventory and enhance customer satisfaction. The following are several common types of failures, cause analysis and recommended solutions:
1. Motor failure
Reason: Motor damage or starting capacitor failure.
Solution: Contact professional maintenance personnel to check or replace the motor.
2. Loose or broken belt
Reason: The belt is aging or loose, resulting in the inability to drive the inner drum.
Solution: Check and replace the belt.
3. Door lock failure
Reason: The door lock is not locked or damaged, and the washing machine cannot start.
Solution: Check the door lock and replace it if necessary.
4. Water level sensor failure
Reason: The water level sensor failure causes the washing machine to misjudge the water level and cannot enter the washing program.
Solution: Check or replace the water level sensor.
5. Control board failure
Reason: The control board is damaged and the motor cannot be controlled normally.
Solution: Contact after-sales service to check or replace the control board.
6. Overload protection
Reason: Too much clothing causes the motor to overload and trigger the protection mechanism.
Solution: Reduce the clothing and restart.
7. Power supply problem
Reason: Unstable voltage or poor contact of the power cord.
Solution: Check the power cord and voltage to ensure normal power supply.
8. Foreign objects stuck
Reason: Foreign objects stuck in the inner drum or drain pump.
Solution: Check and remove foreign objects.
9. Program error
Reason: Program setting error or system failure.
Solution: Restart the washing machine or restore factory settings.
Note:
Before inspection or maintenance, be sure to turn off the power to avoid the risk of electric shock.
If you cannot solve it yourself, it is recommended to contact a professional maintenance personnel.
By following these steps, the problem can usually be found and solved.
