ABT72989202 Dishwasher Pump Casing Assembly – The essential fix for an LG dishwasher that won't drain, leaks from the bottom, has a noisy or grinding pump, or won't circulate water properly. The pump casing assembly is the central housing at the bottom of your dishwasher that contains the wash pump and drain pump components. It serves as the sealed chamber where water collects from the tub and is either pumped through the spray arms for washing or expelled through the drain hose. When the pump casing fails — due to cracks, warping, seal deterioration, or physical damage — water can leak from the bottom of the dishwasher, the pumps may not function properly, or the dishwasher may fail to drain or wash effectively. Common signs of a failed pump casing include water pooling under the dishwasher, visible cracks in the housing, the dishwasher not draining completely, weak spray arm pressure, unusual pump noises, or error codes related to drainage or water circulation. This genuine OEM LG part directly replaces ABT72989206, ABT72989201, and ABT72989203. Fits LG and Kenmore Elite dishwashers. Moderate to advanced 45–60 minute DIY repair that restores proper pump function and eliminates leaks.
