This Part Fixes These Problems

Will Not Drain

Washer stops mid-cycle with standing water in drum; drain pump motor failure prevents water from being expelled through the drain hose.

5E / SE / SC Error Code

Samsung displays 5E, SE, 5C, or SC error codes indicating a drain system fault caused by a failed or seized pump motor.

Loud Noise During Drain Cycle

Buzzing, grinding, or rattling sounds during the drain portion of the wash cycle point to a worn impeller or failing pump motor bearings.

Washer Leaks

A cracked pump housing or deteriorated O-ring seal causes water to leak from the bottom or rear of the washing machine.

Clothes Wetter Than Normal

Insufficient drainage results in excess water remaining in the drum, leaving laundry soaking wet after the spin cycle completes.

💡 Pro Tip: How to Know Your Drain Pump Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Washer displays 5E, SE, SC, or 5C error codes indicating drain failure

⚠️ Water remains in the drum at the end of the cycle — washer will not drain

⚠️ Loud buzzing, grinding, or humming noise during the drain portion of the cycle

⚠️ Clothes come out excessively wet; washer leaks from the pump area

🔍 Diagnostic Tip: Use a multimeter to check the drain pump motor for continuity. If the motor shows no continuity, or receives power but will not run, replacement is required. Note that drain pump motors are not repairable — they must be replaced as a unit.
