Dave J San Dimas , CA September 18, 2021 Appliance: Model 49962600 Code f21 drain time out. Replace the drain pump. Turns out a penny got into the pump and knocked all but one of the impeller blades off. The procedure was straightforward on the video. Total of 15 minutes to replace the pump. Easy, peasy. Thanks Parts pros! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
