Washing machine

A washing machine, comprising:

• a washing drum for accommodating washings;
• a stirring component configured to face the washings from a lower side inside the washing drum and capable of rotating in a manner of stirring the washings in the washing drum;
• a motor for rotating the stirring component;
• an execution unit for executing water supply and drainage for the washing drum or controlling a voltage applied to the motor to rotate the stirring component, and for executing washing operation comprising a washing process for rotating the stirring component in a state that water is stored in the washing drum and a dewatering process after the washing process;
• a threshold setting unit for setting a specified threshold according to a size of a load of the washings in the washing drum;
• an acquirement unit for acquiring an index which indicates a size of resistance generated by the washings in the washing drum to rotation of the stirring component during the washing process;
• and
• a judgment unit for judging that the washings in the washing drum are in a state unsuitable for the dewatering process when the index exceeds the specified threshold since the resistance in the washing process is less than the specified resistance.
