Water Level Sensing Monitoring: Detects the amount of water entering the drum in real time, sends signals to control the water inlet valve, matches the water level to the amount of laundry, adjusts water usage reasonably, and saves everyday water consumption. Stable Signal Transmission: The sensing feedback is smooth, and signal transmission has minimal delay or errors, ensuring the washing program runs in an orderly manner and reducing program errors or unexpected stoppages. Vibration Overload Protection: Captures abnormal vibration values of the machine, sends slowdown signals when clothes are unevenly piled, cushions the impact caused by imbalance, and slows down wear on the shock absorbers and drum. Spin Speed Balance Detection: During spinning, detects the drum's shaking amplitude, feeds the data back to the mainboard to adjust speed, slows down when the drum is off-center, reducing large shakes of the machine and knocking noises.
