ABSTRACT:
In a method for operating a washing machine, the accumulated value representative of the number of washing works done in the washing machine is updated and stored in a nonvolatile memory each time such washing work is done. The accumulated value is compared with a predetermined value representative of a tolerance limit number of washing work of such washing machine. In case that the accumulated value is beyond the predetermined value, the washing machine is made inoperative. The user may be informed visually and/or acoustically of the inoperative condition of such washing machine.
