Possible Causes of F21 error code:

• Clogged drain hose: Check for any kinks, clogs, or debris blocking the drain hose. Clean the hose and filter according to your user manual.
• Clogged drain pump: Debris might be stuck in the drain pump itself, hindering its function.
• Faulty drain pump: In rare cases, the pump itself could be malfunctioning and unable to drain water effectively.
• Drain hose obstruction outside the washer: Check for clogs or blockages in the drainpipe where the hose connects.
• Faulty control board: Less likely, but the control board might be misinterpreting sensor readings or sending incorrect signals to the drain pump.

Important Note:

Determining the exact cause of the F21 error requires knowing your specific Maytag model and its year of manufacture. Different models might have additional interpretations or troubleshooting steps.
