Part W11814182 Upper Spray Arm Assembly

Purpose

Distributes wash water for cleaning

Details

This upper spray arm assembly distributes high-pressure water throughout the dishwasher tub during the wash cycle to ensure dishes, glasses, and utensils are cleaned evenly. Located under the upper rack, it spins to direct jets of water over all load levels. A damaged, cracked, or clogged spray arm can lead to poor cleaning performance, spots, or missed areas. This genuine OEM assembly replaces older part numbers such as W11545334 and W11174340 and restores effective water distribution. Compatibility varies by model; confirm with your model’s diagram before ordering. :contentReference[oaicite:2]{index=2}
