Descale advanced warning
44
When there are approx. 2 operating hours remaining before
the next descaling, the k indicator light begins to flash red.
The light will flash more rapidly as the time counts down, until
it stays on permanently.
Descaling can be started at any time whilst the red k
indicator light is flashing by pressing the j button.
If the k indicator light is permanently on, the remaining
operating hours have expired.
You can still finish your ironing, however, the appliance must
carry out descaling next time it is switched on, before any
more ironing is done.
The residual water container can become hot during the
descaling process. Only remove and empty the residual
water container, when prompted to do so by the 2
indicator light.
Otherwise hot water could spill out and cause injuries
and/or damage to the appliance.
To prevent unwanted removal of the container, set the
appliance to its lowest working position (see "Adjusting the
height"). The appliance must be put back into its highest
working position to remove the residual water container.
The descaling process can be interrupted by switching the
appliance off with the s button. When it is switched back on,
the descaling process will resume from the stage at which it
was interrupted.
