Method to control a washing machine and a washing machine

A washing machine comprising:

• a tub;
• a drum, the drum being rotatably mounted inside the tub and configured to contain laundry to be washed;
• a water inlet configured to introduce water into the tub and/or the drum;
• a first weigh sensor configured to calculate a first weight of the laundry;
• a second weight sensor configured to calculate a second weight of the laundry;
• a control panel;
• a memory storing information about one or more washing cycles;
• a processor configured to:
• receive information about a set washing cycle;
• obtain a value of the first weight of the laundry from the first sensor before water is supplied to the drum and/or tub through the water inlet;
• calculate a first duration of the set washing cycle on the basis of the first weight;
• display the first duration;
• compare the first weight to a first threshold;
• upon determining that the first weight is above the first threshold:
• obtain the second weight of the laundry present into the drum from the second sensor after water has been introduced into the drum,
• calculate a second duration of the set washing cycle on the basis of the second weight, and
• display the second duration in place of the first duration;
• and
• upon determining that the first weight is below or equal to the first threshold:
• gradually update the first duration while executing the set washing cycle.
