Abstract
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 level in a wash chamber or other tank provides the ability to identify a progressively fouling electrode. A system and method of automatically priming one or more chemical feed lines of a warewasher is also described.
