Diverter Motor
The diverter motor rotates a disc that directs water to either the upper or lower spray arms. If the motor fails or the plastic cam shears, the dishwasher will fail to transition water flow to the top rack, leaving it without spray pressure during the wash cycle. This is a common failure point where the internal motor windings fail or a leak at the shaft seal shorts the component.

Upper Wash Arm Assembly
The upper spray arm is driven purely by hydraulic pressure. If the centrifugal spray jets become clogged with mineral deposits or debris, or if the plastic seam of the arm has split, the arm will fail to rotate or provide the necessary spray pattern to clean dishes. Because these arms are ultrasonic-welded, internal debris usually cannot be removed, necessitating a full replacement.

Water Feed Tube/Manifold
This manifold transports water from the sump to the upper spray arm. If the docking port where the top rack connects to the tube is cracked, or if the manifold has become unseated from the back wall, water pressure will bypass the spray arm and leak directly back into the tub, resulting in zero mechanical scrubbing action on the top rack.
