loud noise at the end of draining

I have a Kenmore 110.21102012. When the machine is draining water you see the water level on the tub going down and you hear the water on the drain hose, but when most of the water is gone then starts making a loud noise to finish the draining. The technician told that is normal on this machine to make that loud noise that comes from the water pump. Is that asseveration correct?
