  • Patent number: 6138692
    Abstract: A method for operating an automatic dishwasher in a manner to minimize the deposition of contaminants or filming on the dishes is provided. The present invention contemplates that objectionable filming on washed dishes or dishware items may occur if residual water left on the dishes at the end of the final drain step is not given a chance to drip off or drain from the dishware. The present invention provides for a drip period following the final drain step in the dishwashing cycle. The drip period provides an opportunity for gravity assisted draining or "drip-off" of residual water from the dishware items prior to evaporation such that the minute particles which are suspended in the residual water are not deposited onto the dishes. During the drip period, rapid evaporation of residual liquid from the dishware items is prevented.
