The Upper Dish Rack is an OEM replacement part  for Whirlpool dishwashers. Located on the upper level inside the tub, it provides an area for washing smaller dishes, utensils, and glasses. 

Causes of a bad upper dish rack can include warping or cracking of plastic materials from prolonged use or excess weight loads. Mineral buildup over time may cause rack shelves to become rigid.

Symptoms include:

• Inability to fit or hold delicate items securely  
• Dishes or glassware falling or shifting during rotation
• Food particles or residue collecting on lower surfaces
• Loose or misaligned rack shelves that don't dry properly

Compatible models include Maytag, Amana, KitchenAid, and select Kenmore dishwashers.
