Possible solution
• If the appliance is too loud, you can change the fan speed
to a lower fan speed level. When using the appliance in a
bedroom at night, choose the silent speed.
• Perhaps you did not reset the filter lifetime counter. Switch
on the appliance. Then press and hold the power On/Off
button for 3 seconds.
• The sensor has malfunctions. Contact your Philips dealer or
an authorized Philips service center.
