KitchenAid Dishwashers: Wash System and Performance Issues
KitchenAid dishwashers are engineered for thorough cleaning with features like the Clean Water Wash system, which uses a micro-filtration process to continuously remove food particles from the wash water during the cycle. This ensures that dishes are washed in clean water throughout the entire cycle rather than being recirculated in progressively dirtier water. The ProWash cycle uses sensor technology to monitor soil levels and water temperature, automatically adjusting the cycle length, water usage, and temperature for optimal cleaning results.
When a KitchenAid dishwasher begins leaving food residue on dishes, failing to dry properly, or producing unusual noises, the issue typically involves one or more components in the wash system. A worn wash impeller reduces water pressure through the spray arms, resulting in weak cleaning coverage. Clogged spray arm nozzles prevent water from reaching all areas of the dishwasher cavity. A failing circulation pump reduces overall wash-system pressure. A defective water-inlet valve limits the volume of water entering the dishwasher, leaving insufficient water for proper cleaning.
Our NYC Sub-Zero & Viking technicians disassemble and inspect the complete wash system during a KitchenAid dishwasher service call. We check spray arm rotation, impeller condition, pump output pressure, water-inlet valve flow rate, and filter cleanliness. This thorough approach ensures we identify and resolve the root cause rather than treating symptoms. We carry common KitchenAid dishwasher parts -- including impellers, pumps, inlet valves, and door latch assemblies -- for same-visit repair whenever possible.
