The upper sprayer assembly (12176000022224) in your Midea dishwasher may be the reason for poor cleaning performance. When water isn't distributed evenly across the dishes, it might indicate wear or damage to this component. A genuine part for Midea dishwashers, it fits models such as the 18-inch panel-ready, front control dishwashers in black, stainless steel, and white. Before purchasing, check your dishwasher's model number for compatibility.
