Error codes
An error is indicated by an acoustic signal and an error code is displayed.
E. g.:
If faults cannot be eliminated directly, you must perform a RESET (see „Resetting parameters to the factory settings“)!
If the faults still cannot be eliminated, the appliance must be inspected by a technical service.
