    Question Whirlpool Duet washer error 21

    Model Number: WFW8300SW02
    Brand: Whirlpool
    Age: 1-5 years

    My Whirlpool Duet washer consistently gets error 21. I have cleared the drain plug an pump including the hose above the pump several time with little or no lint. Is there a chance the pump is starting to fail?

    Yes it could be the pump that is going bad. When the washer drains the water out before the spin cycle, does it drain at a fast rate? Have you inspected the impeller on the drain pump to make sure there is no left to right play or broken fins on the impeller? Let me know what you find.

    This is the drain pump for your model washer:
