Editing Washing machine (section)

====Reversible motor====
In many current top-loading washers, if the motor spins in one direction, the [[Transmission (mechanics)|gearbox]] drives the agitator; if the motor spins the other way, the gearbox locks the agitator and spins the basket and agitator together. Similarly, if the pump motor rotates one way it recirculates the sudsy water; in the other direction it pumps water from the machine during the spin cycle. Mechanically, this system is very simple.<ref name="uncleharrywizard.com"/>
