ABSTRACT:
An improved float assembly for a dishwasher liquid fill system includes cam means on the float stem. The cam includes a first portion operative, upon the liquid rising to its normal fill level, to maintain a switch in its circuit closing position allowing the fill valve to be opened at selected intervals during the operational cycle. Upon the float being buoyed upwardly by the liquid level rising above its normal-fill level to an over-fill level the cam means is operative to retain the float at an elevated position permitting the dishwasher to complete its operational cycle after which the float may be manually reset to its lower position to again permit normal operation of the dishwasher.
