Methods for controlling warewasher wash cycle duration, for detecting water levels within a chamber and for priming warewasher chemical feed lines, as well as corresponding systems

摘要

A system and method of selectively extending a wash cycle duration of a warewasher beyond a set minimum duration provides suitable cleaning of wares while at the same time seeking to increase the number of wash cycles per unit time. A system and method for detecting water (L1,L2,L3) level in a wash chamber (10) or other tank provides the ability to identify a progressively fouling electrode (106). A system and method of automatically priming one or more chemical feed lines (130,132,134) of a warewasher is also described.
