Could a failing Drain Pump cause the WHIRLPOOL WDT710PAH to have symptom: Water In Bottom?

The drain pump utilizes a permanent magnet motor that can suffer from magnetic decoupling or internal seal leakage. When the motor fails to generate sufficient torque, it cannot overcome the static head pressure of the drain hose, resulting in a failure to evacuate the tub. This component is the primary electromechanical drive responsible for fluid displacement during the drain phase.

Could a failing Drain Hose Check Valve cause the WHIRLPOOL WDT710PAH to have symptom: Water In Bottom?

This elastomeric flapper valve is designed to allow one-way flow out of the sump. Over time, the material can warp or become fouled with debris, failing to create a hydraulic seal once the pump de-energizes. This allows the volume of water remaining in the drain hose to flow back into the dishwasher tub via gravity.

Could a failing Dishwasher Fine Filter cause the WHIRLPOOL WDT710PAH to have symptom: Water In Bottom?

Accumulated organic matter and lipid buildup can blind the fine mesh of the cylindrical filter. This restriction increases the Net Positive Suction Head (NPSH) required by the pump, leading to cavitation where the pump impeller spins within a pocket of air or foam rather than moving liquid, leaving water in the basin.
