Abstract
An improved float to prevent over-filling of a dishwashing machine including a cylindrical main float body, a skirt attached to the main float body and extending outwardly and downwardly therefrom, and a float stem. The main float body includes a lower portion which extends downwardly beyond a lower terminal portion of the skirt, and serves as a suds stop to prevent suds created during operation of the dishwasher from rising up within the hollow interior of the main float body and flowing down a stand pipe upon which the float is mounted. The lower portion of the main float body includes a slotted opening which serves as a vacuum breaker to prevent a vacuum from being created within the main float body which would cause the float to adhere to bottom wall of the dishwasher tub.
