Abstract
A full automatic washing machine includes a non-volatile memory, such as EEPROM, for storing data of contents of the washing operation executed at a plurality of times in the past. A control circuit originates the data during execution of every washing operation. The data stored in the non-volatile memory are read out and displayed when some switches on an operation panel are operated in a specific mode. The displayed data serve to find out the cause for trouble or failure in the washing machine.
