Zusammenfassung:	A noise-reducing device for a drain pump of a dishwasher is provided, wherein the drain pump includes a pump motor operably engaged with a pump mechanism disposed within a pump body. The drain pump is adapted to remove dishwashing fluid from a sump of the dishwasher. Such a noise-reducing device comprises a cover member adapted to substantially conformally-encompass the pump body of the drain pump, exclusively of the pump motor, to reduce transmission therethrough of noise generated by the pump mechanism during operation of the drain pump. An acoustic liner is disposed between the cover member and the pump body of the drain pump, in substantial correspondence with the cover member and exclusively of the pump motor. The acoustic liner is configured to further reduce transmission therethrough of noise generated by the pump mechanism during operation of the drain pump. Associated devices and methods are also provided.
