If your dishwasher is not draining, start by checking the drain hose for any kinks or blockages that could be preventing water from flowing out. Ensure that the sink's garbage disposal is clear, as a clogged disposal can impact the dishwasher's drainage. Also, inspect the dishwasher’s filter for any food particles or debris that could be obstructing water flow. If these checks do not resolve the issue, the problem may lie with the drain pump or a malfunctioning check valve.
