Summarised table: qualification - operation - frequency
Generic operator
Homogeneous operator
Should a problem occur, the generic operator performs the first search and, if qualified, eliminates
the cause of the problem and restores the appliance correctly.
If the problem cannot be resolved, turn the appliance off, disconnect it from the electrical mains
and shut all the supply valves. Then contact customer service.
The maintenance technician intervenes when the generic operator was not able to pinpoint the
cause of the problem, or whenever restoration of correct operation of the appliance entails execut-
ing operations for which the generic operator is not qualified.
