Identifying a bad washing machine drain pump involves observing specific operational symptoms. The most common sign is that the washing machine finishes the wash cycle but leaves a full tub of standing water because the pump refuses to expel it, often accompanied by a humming sound or a drainage error code on the digital display. To confirm whether the pump is bad, unplug the washing machine, access the pump housing, and check for jammed debris in the impeller. If the impeller spins freely but the pump motor fails to run when voltage is applied, or if a multimeter test shows broken internal coil windings, the pump is defective and must be replaced.

You can determine if your washer drain pump is bad by observing specific operational symptoms and performing diagnostic checks. The most common indicators include the washing machine failing to drain water completely at the end of a cycle, leaving clothes soaking wet, a loud humming, buzzing, or grinding noise coming from the bottom of the machine during drain cycles, or visible water leaks pooling beneath the front corner of the appliance. To confirm, unplug the unit, inspect the filter trap for clogs, and test the motor winding resistance with a multimeter. You can verify the fix when a new pump successfully evacuates water.
