Reach inside the fan opening to grasp the pump. Tilt the pump up and cut the wire-ties holding the clear plastic discharge line. Remove the discharge line from the barbed stub fitting. Release the cable retaining clip on the side of the pump and cut the wire- ties holding the cable loop. Maneuver the pump into the fan opening with the cable still attached and remove the cover to expose the wire terminals. Remove the wires from the pump and remove the pump from the cabinet. Install the replacement pump in the same manner that the old pump was removed, reversing the procedure.
