Rotor Position Sensor (Hall Sensor)
The Hall sensor monitors the position and speed of the direct-drive rotor by tracking magnetic poles. If the internal logic gates of the sensor fail or become intermittent, the washing machine's control board receives erratic RPM data; the logic interprets these fluctuations as an unbalanced load 'stumbling' the motor, triggering the UE error even if the drum is empty.

Washer Suspension Shock Absorber Kit
These friction-style dampers are responsible for absorbing the kinetic energy of the tub during high-speed rotation. When the internal grease or friction pads degrade, the tub's movement is no longer dampened, causing it to strike the cabinet or oscillate wildly; the control board detects this excessive displacement via an accelerometer and terminates the cycle with a UE code.

Main Electronic Control Board
The control board contains the inverter circuitry and the algorithms that manage load balancing. If the capacitors or processing logic responsible for interpreting signals from the Hall sensor fail, the board may incorrectly identify normal motor harmonics as a critical imbalance, preventing the machine from reaching high-speed extraction.
