ABSTRACT:
A dishwasher is provided with an improved apparatus for protecting the tub from being overfilled in the form of a float having a float stem that is automatically captured upon insertion through a passage in the tub bottom wall such that the float will be restrained against disengagement from the tub bottom wall. The float is vertically movable to operate a control switch for regulating the level of water within the tub. Preferably a retaining ring is carried on a stem of the float which is automatically biased through a varying diameter keyway and is subsequently moved to a captured position below the member having the keyway.
