The General Electric WH11X39237 Washer Drain Pump & Filter. This replacement assembly combines a drain pump and filter to help remove water from the washing machine while capturing lint, debris, and other particles before they enter the drainage system. It works by pumping water out of the washer during designated cycle stages and filtering contaminants that could affect operation. Designed for compatibility with select washer models, it plays an important role in maintaining proper drainage and system functionality. Replacing a worn or malfunctioning unit can help restore normal operation, improve drainage efficiency, and support reliable washing performance.
