5 Software service routines
5.1 Service routines overview
5.2 First Run up
The software is restarted, with a “reset event” entered
into the laptop ring memory (see chapter “service”, reset
events).
The cleaning obligation is reset as if a cleaning cycle had
just been done.
A cleaning cycle can be interrupted.
A descaling cycle can be interrupted.
Attention: If a cleaning or descaling cycle has been
interrupted adequate measures must be taken to ensure
that no residues of cleaning or descaling agents remain
in the machine. In this case cleaning or descaling must be
repeated.
The reset of the customer settings program is treated in
the same way by the software, however does not reset the
cleaning and descaling obligations.
