Washer stops mid-cycle and displays F21 (long drain) error code; water remains in drum leaving clothes soaking wet.
Unusual grinding, buzzing, or loud whirring sound coming from the bottom of the washer during the drain cycle, indicating a damaged or seized pump motor.
Machine halts partway through a wash or rinse cycle and will not advance, often accompanied by standing water in the tub.
Puddle of water forming at the front-bottom of the machine caused by a cracked pump housing or failed pump seal.
Washer drains very slowly, takes multiple drain attempts, or leaves residual water in the drum after the spin cycle.
💡 Pro Tip: How to Diagnose a Failing Drain Pump
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays F21 or Sud error code and stops mid-cycle
⚠️ Clothes come out sopping wet — drum fills but won't fully drain
⚠️ Loud grinding, buzzing, or whirring noise coming from the bottom of the washer during drain cycle
⚠️ Water leaking from underneath the front of the machine near the pump area
🔍 Diagnosis tip: First check for blockages (coins, socks, lint) in the coin-trap filter accessible behind the lower front panel. If the filter is clear but the pump motor shows no continuity on a multimeter, or the motor gets power but won't run, replace the drain pump assembly — drain pumps are not serviceable and must be replaced as a unit.
