Out of service/Failure conditions
In particular situations, the VM can be fully or partially out of service.
There are 3 categories (classified by severity):
A. failures due to scheduled maintenance conditions which partially block the VM. By these failures (out of coffee, too many dump in the box, out of cups – in case of cup preselection) the VM is not out of service but its dispensing function is somehow limited ;
B. failures due to scheduled maintenance conditions which block the VM fully. By these failures (out of cups, no water, too many dumps in the box, too high water level in the residues tray) the VM product dispensing is disabled, thus inhibiting the payment systems;
C. out of service conditions which disable the entire VM. The VM is brought to this condition when it detects failures which are not solvable with scheduled maintenance. In this condition, the payment systems are inhibited and no VM load can be operated.
The following table resumes all failure and/or error conditions which may occur on the VM, listing for any of them:
•possible cause description
•category;
•associated code (i.e. the code shown in maintenance and registered in the error log);
•effect on the VM state;
•how to restore the VM normal operation - once the failure/error cause has been removed
