The removable agitator lifts out for impeller-mode washing. The impeller and the drive mechanism remain separate service parts.
What to check before buying
Agitator and tub
The catalogue lists the agitator, impeller and impeller cap separately. The quick-start guide documents owner removal and refitting of the centre agitator for switching wash modes.
Drive and water parts
The parts diagrams identify a separate shift actuator, gearcase, motor and belt. Water-related assemblies include the drain pump and inlet assembly; the tub suspension is listed as a set of four dampers with its bushings and balls.
