Method for monitoring water-charging process and water-discharging process of washing machine

The invention discloses a method for monitoring the water-charging process and water-discharging process of a washing machine. The method comprises the following steps: in the water-charging process or water-discharging process, a computer board reads the water level frequency once after a set period of time; and if the water level frequency is not changed compared with the last water level frequency and the set total times of reading and the total time water level frequency are not changed, a water-charging overtime alarm or the water-discharging overtime alarm is executed. Every time when the computer board reads the water level frequency, the water level is compared with a preset water level to judge whether to reach the preset water level; if so, the water-charging process is stopped or the water-discharging process is started; if not, the water level frequency is compared with the next water level frequency to judge whether the water level frequency is charged; and the preset water level is the washing water level or empty water level. By adopting the method of the invention, the changes of the water level can be detected dynamically in the water-charging process or water-discharging process to judge whether the water-charging or water-discharging state is normal; and when the water-charging or water-discharging state is abnormal, the water-charging process or water-discharging process is stopped and the user is informed through the alarm.
