摘要:
Disclosed is a washing machine failure detection and processing method, comprising the following steps: a PC pointer detection step: respectively detecting various running processes of a washing machine; respectively detecting whether a current value of a logical register is the same as an assigned value after the running of various subprograms is ended, and if the current value is different from the assigned value, judging that a PC pointer fails, and keeping a record of a current failure occurring in which running process of the washing machine according to the assigned value; and when it is judged that the PC pointer fails, waiting for a time t1, and continuing to detect whether the current value of the logical register is the same as the assigned value, and if so, continuing to execute the subprogram, otherwise executing system resetting. In the washing machine failure detection and processing method in the present invention, an internal running error is prevented from occurring in an algorithm of a washing machine, a failure is detected by a system before being found by a user, and a corresponding security control measure is adopted, thereby guaranteeing the secure running of the washing machine.
