Could a failing Drain Pump Assembly cause the KITCHENAID KDTM354ESS to have symptom: Water In Bottom?

The drain pump is a synchronous motor that provides the centrifugal force required to evacuate water through the drain line. Mechanical failure often occurs when the impeller becomes obstructed or the internal motor windings fail due to thermal stress, preventing the pump from initiating the drain phase. Replacing the pump restores the machine's ability to overcome the head pressure of the drain hose.

Could a failing Drain Pump Check Valve cause the KITCHENAID KDTM354ESS to have symptom: Water In Bottom?

This elastomeric component is designed to allow one-way flow out of the sump while preventing gravity-fed backflow from the drain hose. If the rubber degrades or loses its shape, water that has already been pumped out will return to the tub once the pump cycles off. A new valve ensures a watertight seal against returning wastewater.

Could a failing Drain Hose cause the KITCHENAID KDTM354ESS to have symptom: Water In Bottom?

Physical obstructions within the corrugated drain hose can create significant back-pressure that the pump cannot overcome. Over time, solidified fats and food particles can narrow the internal diameter, leading to incomplete drainage. A replacement hose ensures an unrestricted path for the effluent.
