Which of the following is a common sign of a malfunctioning washing machine?

A common sign of a malfunctioning washing machine is excessive shaking and failure to spin. This issue often indicates that there may be an imbalance in the load, a problem with the suspension system, or issues with the motor or belt. When a washing machine is not properly balanced, it can shake vigorously during the spin cycle, which can lead to further mechanical problems and potentially cause damage to both the machine and the surrounding area.

If a washing machine fails to spin, it may also mean that the drive motor is not engaging correctly, the lid switch is defective, or there could be a block in the drain system, preventing water from being expelled. These symptoms often point toward a need for inspection and repair to ensure the washing machine operates effectively and safely.

Routine noise during operation can be expected as machines typically make sounds while functioning, and while excessive noise may indicate a problem, it is not always definitive. Consistent water levels during a wash cycle suggest that the filling mechanism is working properly but do not necessarily imply a malfunction unless it prevents the machine from draining. Automatic door locking is a safety feature in modern washing machines designed to prevent opening during operations, and its presence alone doesn’t signal a malfunction.
