Upper Spray Arm
The spray arm utilizes water pressure to induce rotation via angled jets. Over time, calcium deposits or organic debris clog these apertures, stalling the arm and preventing uniform water distribution. This mechanical blockage results in localized cleaning failure despite adequate pump pressure.

Water Supply Tube Assembly
This component transports pressurized water from the sump to the upper spray arms. A failure in the docking seal at the back wall or a crack in the plastic tube causes a hydraulic pressure drop, preventing the upper arm from spinning or receiving sufficient volume for cleaning.

Heat Pump and Circulation Motor Assembly
In this model, the distribution of water is controlled by a diverter disc integrated into the circulation pump. If the diverter motor fails or the disc becomes jammed, the system may remain stuck in the 'lower rack only' position, mechanically preventing water from entering the upper manifold.
