Clean up foreign bodies
If you hear a foreign object rubbing against the inner wall, check and clean the clothes in the bucket in time.
Balanced layout
If it is dry, it may be that the clothes are unevenly placed, resulting in unstable center of gravity during rotation and hitting the casing.
Smooth installation
The floor on which the washing machine is installed is uneven. Check whether the floor on which the washing machine is installed is uneven. When installing the washing machine, you must choose a flat floor and adjust it to a suitable position.
Replace bearing
The motor bearing or transmission shaft is seriously worn or the bearing is broken. If the gear of the gearbox of the washing machine is not working well, please add lubricating oil. If it is determined that the firmware is damaged, it is best to replace the firmware.
control valve
It is necessary to remove the cylinder head cover and touch the valve rocker arm by hand. If there is noise, you will feel a slight vibration, which is different from the touch brought by other silent valve rocker arms. You can also choose a thickness gauge with suitable thickness to be inserted between the suspicious valve foot and the valve rocker arm. If the noise is reduced, the gap here will be too big. If the valve clearance is too large, it should be adjusted according to the regulations. If the noise is serious, it should be replaced with a new one.
