ABSTRACT:
In a washing machine, during a washing mode, a number of times the washing machine is operated is counted and stored in a memory. Respective numbers of times that error signals are generated at the respective washing steps are counted and stored in the memory. When a checking mode button is pushed, a used mode is converted into the checking mode and simultaneously the number of times the washing machine is operated stored in the memory is displayed. By further pushing of a checking mode button, the respective numbers of times that error signals occurred as stored in the memory are respectively displayed. By pushing a clear button, data stored in the memory are cleared. Thus, during a washing operation, numbers of times that errors occurred at each of the washing steps are separately stored into the memory. During a checking operation, the numbers of times of errors at each of washing steps which are stored in the memory can be displayed on the display part.
