Dishwasher Diverter Motor
The diverter motor drives a cam that rotates a ceramic disc to alternate water flow between the lower and upper spray arms. When the motor fails or the position sensor is compromised, the disc often remains stuck in the 'lower-only' position, preventing water from entering the delivery tube that feeds the top rack.

Circulation Pump and Motor Assembly
The wash motor provides the hydraulic pressure necessary for the entire system. In this model series, the impeller can degrade or the motor torque can drop, resulting in sufficient pressure to spin the lower arm but insufficient head pressure to overcome gravity and friction in the upper wash arms.

Water Supply Manifold / Docking Station
The upper rack connects to the water supply through a rear-mounted manifold using a rubberized docking seal. If the manifold or the rack-side connector is warped or the seal is torn, water pressure leaks into the tub at the connection point rather than being channeled into the spray arms.
