ABSTRACT:
A fluid-handling machine, such as a dishwasher or clothes washer, measures liquid load by detecting liquid pressure oscillations. The machine, which includes both a frame for containing articles and a system for circulating or distributing a liquid in the frame, shuts off flow of liquid provided to the frame when the detected liquid pressure oscillations substantially cease, as determined in accordance with a fuzzy logic control strategy.
