      To check the drain in your Samsung washer, examine the draining pump motor for any foreign objects. Inspect the natural drain for blockages as well. Also, verify all connections and wires are correctly connected and not broken. If the washer malfunctions when the water temperature is high, the pump may need replacing. If the motor stops due to frozen water, remove the ice.
