Upon inspection, the KitchenAid dishwasher was not completing its cycles as expected. A thorough examination revealed an obstruction in the drain system, which was preventing proper water drainage and cycle completion. I carefully accessed the dishwasher's internal components, locating the blockage in the drain hose. After removing the obstruction, I flushed the system with water to ensure no residual debris remained. I then tested the dishwasher, confirming that it completed cycles successfully. The appliance is now functioning correctly, and the customer is satisfied with the restored performance.
