The present invention relates to a method of alarming an abnormality of a washing machine. In particular, when an abnormality in function or use occurs during the washing process, the user can be alerted to whether the user can take action or request a service. The present invention relates to an alarm method of a washing machine that can be displayed.

In general, when an abnormality such as a water supply error, drainage error, PCB error, washing motor, dehydration error, etc. occurs in the initial washing machine or during washing, the washing machine stops washing and alarms and displays an abnormal signal.

However, in the washing machine, the alarm display due to the abnormality is not displayed so that the user can easily know in which part the abnormality has occurred, and it is indicated by a sign so that the user does not know the abnormal signal, unless the user is familiar with the abnormal signal. If you do not look in the service manual when you occur it is not known.

Therefore, when the abnormal alarm occurs, the user cannot take action even when the user views the service manual, or if there is a component failure error in the function, but the user does not know the service manual such as water supply error, drainage error, or dehydration error. Even in the case of an error that can be carried out by taking a rest and simply taking an action, the user stops washing unconditionally and requests a service without looking up the service manual by an alarm indication unless the user easily knows it. In addition to the hassle caused, there is a problem that waste unnecessary washing time.

An object of the present invention is to display an alarm by distinguishing whether a user should take action or request a service when an abnormality occurs in the function or in use during the washing process. If the user can simply take action, the above problem is to immediately take the action and to wash the laundry, thereby reducing waste of washing time due to unnecessary service requests.

In order to achieve the above object, the present invention provides a method for cleaning a washing machine, the method comprising: washing a laundry by a series of washing strokes initially set; determining whether the washing machine is in a normal operating state while washing is being performed; If the washing machine is in the normal operating state, the ongoing step, if the washing machine is not in the normal state, the step of generating an abnormal alarm in use and function, and the abnormal alarm generated in the step is determined whether the user action is abnormal If the abnormality is not an abnormal user action at the step, displaying the service request abnormality; if the abnormality is an abnormal user action at the step, displaying a user manual and displaying a service manual page. It is characterized by consisting of steps.
