Claims6
An electrically powered automatic shutoff overflow controller for use in shutting off an electrically powered liquid processing device when an undesirably high level of liquid is sensed in a liquid containment of the device, the controller comprising a circuit engaged between the device and a source of power therefor, the circuit including a connector engaged to the source of power for the device, an atria to which the device is electrically engaged, a normally closed relay incorporating a delay timer positioned between the connector and the atria, and a conductive sensor within a probe placed at a desired level within the liquid containment and, when the probe becomes immersed in liquid, causing an audible warning to be produced and interrupting the flow of power from the source to the device.
