MHN30PDCWW0 Whirlpool Washer - Instructions

Unplugged washer first! Removed front bottom panel by removing three screws, unscrewed the Drain Plug assembly by turning drain plug counter clockwise with a bucket to catch excess water from washer. Used pliers to remove spring clamps from washer agitator drain hose and then removed the spring clamp from the hose going to drain. Checked hoses for obstructions, then Slide Drain Pump assembly up to the right to remove. Then installed new Drain Pump assembly by sliding pump into slot to the left. Connected the agitator and drain hose to new Drain Pump and fastened with spring clamps. Plugged in AC line cord and turned washer on and started a quick wash cycle to check for leaks and to see if the water drained from washer properly. The water drained from washer and error code did not appear. The error code F21 reappeared during the second wash cycle. After closer inspection with a flash light, I found a large piece of cloth caught between the washer agitator and washer tub covering the drain by shining the flash light up towards the Agitator tub. This was solved by removing the Drain Pump assembly and all of the drain hoses again. Then removing the the large hose from the agitator tub and then removing the large piece of cloth from agitator tub. After reassembly, the washer worked like new!
