Ah, the age-old plumbing problem! If you find your dishwasher filled with water at the end of a cycle, it's often due to a clog or blockage in the drainage line. Over time, food particles, detergent buildup, and other debris can obstruct the dishwasher drain, preventing water from draining out. Regular dishwasher maintenance, like cleaning the strainer and checking the drain hose, can help prevent this issue.
