Abstract

A fluid-handling machine, such as a dishwasher or clothes washer, incorporates a device for measuring liquid load that includes a sensor for detecting liquid pressure surges. The machine may further include a frame for containing articles, a system for circulating or distributing a liquid in the frame, and a controller, responsive to the device, for controlling the amount of liquid provided to the frame so that enough liquid is provided to ensure that there is a sufficient amount for a wash cycle.
