overheat protection tripped.
The steam generator has an overheat protection which trips if
the temperature in the steam generator goes too high. If the
element overheats, the power is cut to the element and error code
F7 appears because the disinfection temperature has not been
achieved. When the error code has been reset, the machine can
be restarted. The steam generator is reset automatically. To make
sure that the overheat protection does not trip immediately, the
steam generator should be allowed to cool down before a new
process is started.

Figure 22. The steam generator’s overheat protection (1)
The fuse may have tripped because the temperature sensor is
faulty, because of incorrect operation, because of foaming additive,
or because the water supply is shut off or blocked.
If the fuse has been triggered on numerous occasions, it should be
replaced because of fatigue.
