A washing machine that finishes a cycle with water still inside can be frustrating. Drainage problems can have several causes, and the right solution depends on the appliance and what you are noticing.
Before arranging service, make a note of when the issue happens, whether you hear unusual sounds and whether any error message appears. Avoid forcing the machine to run repeated cycles if it is leaking or behaving unusually.
If the problem continues, share these details with an appliance professional so they can advise on the next step.
