Don't you think it a bit strange that both drawers should suddenly have problems draining at the same time. The chances that both drian motors have gone bad is pretty remote. More likely to be a blockage or problem with the drain pipe set up. Maybe too long a hose or too high above the drawer for the pump to push the water. The whole rotor has to be replaced. The fins come as part of the rotor.
