The service stamp is input via the following form:
7.4.14.1 Group definition
Specific fault groups are allocated to the working points. When a
working point has been selected, its fault group is activated for
selection in "Input fault code".
A690 = Instantaneous water heater replaced,
Fault group
F 4 00 = Coffee water heater blocked
7.4.14.2 Service stamp structure
This concept of the service stamp enables each service centre to
evaluate what work was carried out during the last service and which
faults were rectified. In all 3 service entries are saved in the appliance.
The first stamp is never overwritten. In the case of stamps 2 and 3 the
older stamp is overwritten. Therefore it is always obvious when the 2
previous services were carried out.
The definitions as work/fault codes, major faults, employee number
and number of services are included only in the last service entry
in the appliance.
The service date, number of the service centre and invoice item are
saved for all three entries.
