ENGLISH
Note: When the power on/off light, lter replacement light 2 or 3/4 and the
‘REPLACE FILTER’ light are on continuously, the appliance is locked (see section
‘Filter maintenance’ in this chapter for more information).
Approximately 1 day before the appliance locks, it beeps every 30 minutes
to inform you that one of the lters needs to be replaced.
When the appliance is locked, you hear a beep when you press any button.
You can switch off the appliance by pressing and holding the on/off button.
If the appliance is locked:
1 Check which lter needs to be replaced (see section ‘Filter cleaning
light and lter replacement lights’ above).
2 Switch off the appliance and unplug it.
3 Replace the appropriate lter (see section ‘Replacing the lters and
resetting the appliance’ below).

insert lters.
