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).
