Abstract: A method for operating a washing machine having a tub with a drum rotatably mounted in the tub and configured to hold a fabric load and a liquid recirculation system configured to recirculate liquid from the tub to the drum comprises a pre-wash step; a heating step comprising introducing steam into the tub and/or the drum; and a washing step comprising washing the fabric load with a second volume of liquid greater than the first volume of liquid. The pre-wash step can comprise recirculating a first volume of liquid between the tub and the drum without submerging a portion of the drum in the liquid and rotating the drum. In another embodiment, the pre-wash step can comprise recirculating a first volume of liquid between the tub and the drum to achieve a fabric load weight to liquid weight ratio of between about 1:0.5 and 1:2.7.

Abstract: A method for treating a biofilm in an appliance comprising a structure defining a cleaning chamber, wherein the biofilm resides on the structure, comprises treating the structure with heat. The heat may sanitize the structure, kill microorganisms in the biofilm, and loosen the biofilm from the structure. Optionally, the biofilm may be rinsed from the structure following or during the treatment with heat.

Abstract: A method of sanitizing a washing machine, including the removal of a bio film from the wash chamber of a clothes washer.

Abstract: An electric iron having a housing (1) and a soleplate (2) in which at least one outlet opening (10;15;34;45) is provided, means (8;19;28;39;43) for generating a fine liquid spray or foam or steam, and means (5) for delivering said generated fine liquid spray or foam or steam through said outlet opening. According to the invention, the iron is provided with detection means (12,14;22,23;35,36;49) for detecting the presence of a surface (7a) in the proximity of the sloplate (2) and for generating a detection signal in response to said detection, and with control means (6) for controlling the delivery of said fine liquid spray or foam or steam in response of said detection signal. For example, the detection means comprise a movable spring-loaded contact element (12) located in the soleplate (2), said element (12) activating a switch (14) for generating said signal when the soleplate is positioned against said surface (7a) and thus depresses said element (12).

Abstract: A fabric treating appliance utilizing steam for treating the fabric and having a steam generator with a conduit for directing the steam

Abstract: A fabric treatment appliance comprises a steam generator having a chamber configured to hold water; a supply conduit configured to transport water to the steam generator chamber; a temperature sensor configured to sense a temperature representative of the steam generator chamber at a predetermined water level in the steam generator chamber; and a controller coupled to the temperature sensor and configured to control flow of water through the supply conduit based on the sensed temperature to control the level of water in the steam generator chamber. The disclosure provides methods of water supply control that can employ the temperature sensor.
