• Inadequate cleaning of dishes on the lower rack
• Uneven or inconsistent water spray
• Clogged or obstructed spray nozzles
• The arm not spinning or rotating correctly

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