The f21 error code can occur if your Whirlpool duet washer’s drainage system is clogged. This blockage can happen when there’s debris, fabric lint, or foreign objects like coins, hairpins, or pebbles in the washer. A blocked drain pump filter or kinked drain hose can also cause this kind of error.

Your home’s drainage system can also contribute to the f21 error code. For instance, if your drain hose is not installed correctly, it could cause a blockage in the washer’s drainage system.
