The Spray Arm is an OEM part for Whirlpool dishwashers. It plays a crucial role in the cleaning process by rotating and spraying water onto the dishes to remove food particles and debris. The spray arm measures approximately 18.75 inches long and 2 inches wide.

Causes of a bad spray arm can include clogging due to food particles or mineral deposits, cracks or breakage from regular use, or a malfunction in the rotating mechanism. These issues can impede the spray arm's ability to distribute water effectively, leading to poor cleaning performance.

Symptoms of a bad spray arm include:

  •  Dishes not being cleaned properly
  • Noticeable clogs or blockages in the spray holes
  • The spray arm not rotating during the wash cycle

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
