If the washing machine gearbox fails during use, what are the common problems and symptoms?

If the washing machine gearbox fails during use, various problems and manifestations may occur. The following are some of the common problems and specific manifestations:

Abnormal noise: When the gearbox fails, the washing machine may make abnormal noises during operation, such as harsh metal friction or knocking sounds. Gear wear is one of the common causes of this unusual noise. Gears are the core transmission components in the gearbox of a washing machine. After long-term use, their surfaces may gradually wear away due to friction. When the wear is severe, the fitting gap between the gears will become larger, causing the transmission to be unstable and causing harsh metal friction sounds. This sound is usually particularly noticeable when the washing machine is started or when the washing mode is changed, causing discomfort to the user's hearing. In addition to gear wear, damaged bearings are also a common cause of noisy washing machine gearboxes. As a key component supporting the rotation of gears, bearings bear the huge pressure and friction of gear rotation. If the bearings are damaged or worn excessively, they will cause uneven rotation, resulting in knocking sounds or vibrations. This noise will not only affect the normal operation of the washing machine, but may also cause damage to other parts of the washing machine. In addition, loose transmission components are also one of the causes of abnormal noise in the gearbox.

Weak wash: Damaged gears are a common cause of weak wash. After long-term use and friction, the gears in the gearbox may suffer from wear, breakage, or deformation. Once the gears are damaged, the fit gap between them will increase, resulting in reduced power transmission efficiency. In this way, even if the motor is running normally, the rotation speed and strength of the washing barrel will be significantly weakened, thus affecting the washing effect.

Water and oil leaks: If the gearbox is poorly sealed or damaged, it may cause the washer to leak water or oil while it is running. The liquid inside the gearbox, whether it is water or lubricating oil, may seep through the gaps. Once these liquids leak, they will not only reduce the amount of liquid in the gearbox and affect the normal lubrication and cooling of the gears, but will also flow directly into the shell of the washing machine or the surrounding environment. For users, during the laundry process, they may find water or oil stains on the bottom of the washing machine, and even the floor is soaked with liquid.

Increased temperature: Friction inside the gearbox is one of the main causes of increased temperature. When components such as gears or bearings are damaged or severely worn, the contact surfaces between them will become uneven and the friction will increase. This friction will not only reduce the working efficiency of the gearbox, but also generate a large amount of heat, causing the temperature inside the gearbox to rise rapidly.

Seized or stopped turning: A stuck gear is one of the common causes of a gearbox seizing or stopping turning. Gear jamming may be caused by the fitting clearance between gears being too small, serious gear wear, or foreign matter on the gear surface. When the gear is stuck, the power transmission link of the entire gearbox will be interrupted, making the rotating part of the washing machine unable to operate normally. Users may hear unusual noises or feel the vibration of the washing machine when using the washing machine, which are obvious signs that the gears are stuck.

For these problems, it is recommended that users pay attention when using the washing machine. Once any abnormality is discovered, they should contact professional maintenance personnel for inspection and repair in time. At the same time, regular maintenance and upkeep of the washing machine gearbox is also an important measure to prevent failures.
