The dishwasher spray arm is responsible for distributing water to thoroughly clean dishes. Typically positioned at the bottom and/or top of the dishwasher, it rotates in a circular motion to cover all areas effectively. Its primary function is to eliminate food particles, grease, and grime, ensuring dishes are impeccably clean. Most dishwashers feature two wash arms, one at the top and another at the bottom, to optimize cleaning efficiency. The effectiveness of the dishwasher wash arm relies on its design and the number of spray jets, which determine water pressure and distribution. This design guarantees that all dishes receive sufficient water coverage. Certain wash arms even come with adjustable pressure settings to accommodate different types of dishes, such as delicate glassware or sturdy pots and pans.
