Could a failing Dishwasher Diverter Motor cause the KITCHENAID KDPE234GPS to have symptom: Not Cleaning?

The diverter motor governs the distribution of water to the upper spray arms via a rotating cam disc. If the motor's internal gear train fails or the shaft seal leaks, the disc remains static, often blocking water flow to the top rack specifically while allowing the bottom arm to function. This mechanical failure prevents the required hydraulic pressure from reaching the upper wash zone.

Could a failing Circulation Pump and Motor Assembly cause the KITCHENAID KDPE234GPS to have symptom: Not Cleaning?

The circulation pump generates the necessary head pressure for the entire wash system. If the impeller becomes obstructed or suffers from cavitation damage, the pump cannot maintain the pressure required to overcome gravity and reach the uppermost spray jets. This results in weak or non-existent spray at the top rack while the lower rack may still receive enough volume for marginal cleaning.

Could a failing Manifold Water Feed Tube cause the KITCHENAID KDPE234GPS to have symptom: Not Cleaning?

The upper rack relies on a docking connection to the rear manifold tube to receive water. If the docking seal is degraded or the plastic manifold is cracked, the system suffers from a pressure drop at the junction point. This fluid-dynamic loss prevents the spray arm from reaching the necessary RPMs to effectively distribute water across the top rack surface.
