  • Patent number: 5493877
    Abstract: A water level sensor and alarm system for use with a washing machine. The water level sensor and alarm system includes a control box, a control circuit, a plurality of probes, and a washing machine unit and drain. The low level sensor and alarm system will connect directly to a washing machine and drain tub and/or drain conduit in order to monitor an overflow of water during the rinse cycle of a washing machine. If water has exceeded a certain height, and is beginning to overflow, the system will automatically cut all power to the washing machine unit and thus turn the washing machine unit off until the unit is reset after the clog in the drain has been corrected.
