1. A washing machine comprising:
an input device configured to receive user input;
a weight sensor configured to sense an amount of laundry received in the washing machine;
a driver configured to perform operations including water supply, drainage, washing, and spin-drying in the washing machine;
an output device configured to provide washing machine status information and washing time information; and
at least one processor that is in communication with the driver, the input device, the weight sensor, and the output device,
wherein the at least one processor is configured to:
estimate, based on a previous setting of a previous washing operation, an estimated setting for a current washing operation, the estimated setting including a water supply time, a drainage time, and a spin-drying time,
obtain the user input through the input device,
obtain the amount of laundry from the weight sensor,
determine, based on the estimated setting, the user input, and the amount of laundry, a washing time for the current washing operation, and
determine, based on a difference between the estimated setting for the current washing operation and the previous setting of the previous washing operation being greater than a predetermined value or ratio, that the washing machine is in an abnormal condition indicating that at least one condition of the washing machine is impairing performance of the washing machine.
