13.1. Safety thermostat – Manual
resetting
Warning! The operation described hereun-
der must strictly be performed solely by an
installation and service technician that has
been duly authorised by the manufacturer
to doing so.
Subsequent to a failure during machine use, the
safety thermostat might kick in to prevent even more
severe damages occurring to the boiler.
In order to reset the standard machine functions, it
is first necessary to remove the failure that originally
caused the safety thermostat to kick in and then to
reset the standard machine conditions by pressing
on the red (RESET) pushbutton, as illustrated in
figure 13.
