What is the most common problem with the KitchenAid dishwasher?

What is the most common problem with the KitchenAid dishwasher is not cleaning dishes well and leaving white film, food particles, and spots, followed by not draining and leaving standing water. For KitchenAid models like KDTM604KPS and KDFE104HPS made by Whirlpool Corporation, top failure is filter under lower rack clogged with food debris that blocks water circulation and causes poor cleaning and white chalky film due to mineral and food buildup, accounting for about 25 percent of service calls, fix by removing lower rack, twisting cylindrical filter, rinsing under hot water monthly, and cleaning microfilter. Second most common is spray arm holes clogged with food and hard water deposits that blocks water jets from reaching dishes, clean holes with toothpick. Third is not draining and standing water at bottom due to drain pump clogged with food, glass shards, and grease or failed drain pump at 20 to 40 dollars that causes dishwasher to not complete cycle. Fourth is not drying dishes well due to heating element failed at 30 to 60 dollars or rinse aid dispenser empty. Fifth is leaking onto floor due to door gasket worn after 5 to 8 years. Sixth is door latch failure at 20 to 35 dollars. To prevent most KitchenAid dishwasher problems, clean filter monthly, scrape plates before loading but do not pre-rinse completely as detergent needs food to work, use rinse aid, and run Affresh cleaning cycle monthly to dissolve grease and mineral buildup.
