ABSTRACT:
A dishwasher fill system providing a combination fill control system and timer fill sequence that assures a predetermined minimum quantity of water is present in the dishwashing chamber regardless of the water fill flow rate and the household waterline pressure. The system provides two assured fill levels with a predetermined minimum water level fill cycle portion for a rinse fill and an increased minimum level fill cycle portion for a wash fill. If the rinse fill water level is below its minimum quantity after a predetermined run time, first switch means will energize the timer motor and the fill valve will remain open until said rinse fill minimum level is reached. A fill sensor switch at this point will turn off the water valve and energize the timer motor. During wash fill portions of the cycle the system is as described above with the addition that second switch means will energize the timer motor and the water valve will remain open for a predetermined number of seconds longer than for the minimum fill cycle portion, thereby filling the chamber to its wash fill level.
