Abstract: A washing machine, such as a laundry washing machine, a washing/drying machine or the like, has a tub housing a drum into which the laundry to be washed is loaded. The machine is equipped with at least one tank for a washing agent, and at least one supply duct is afferent to the tank for delivering the washing agent into the tub. A hydraulic washing circuit floods and drains the tank for cleaning purpose. A tank cleaning method is also disclosed.

Abstract: A washing machine, in particular a laundry washing or washing/drying machine, has at least one wash tub, one tank for a washing agent, and one drawer for loading washing agents, in which machine the drawer can be moved to at least a first position, wherein at least a portion of the drawer is in fluid communication with the tub, and a second position, wherein at least a portion of the drawer is in fluid communication with the tank.

Abstract: The present invention relates to a washing machine (2), in particular a laundry washing or washing/drying machine or a dishwasher, comprising: a tub (3) adapted to contain a wash liquid (4), an electric resistance (1) for heating the wash liquid (4), a temperature sensor (5) for detecting the temperature of the wash liquid (4), wherein the resistance (1) and the temperature sensor (5) are put in a condition of thermal exchange by conduction. The invention also relates to a method for evaluating whether the resistance is emerged from or submerged in the wash liquid and to a method for removing calcareous deposits (17) from an electric resistance (1) adapted to heat a wash liquid (4) in a washing machine (2), in particular a laundry washing or washing/drying machine or a dishwasher, characterized in that the resistance (1) is subjected to at least one heating and cooling cycle while the resistance (1) is kept above the wash liquid (4).
