Problem

Possible solution

The appliance is extra

loud.

You haven’t removed all packaging material from the filters. Make sure that

you have removed all packaging material.

The appliance still indicates

that I need to replace a

filter, but I already did.

Perhaps you did not press the filter reset button properly. Plug in the

appliance, press the on/off button and press the filter reset button with a

flat tool.

The appliance stops

operating, although the

power-on light is still on.

The built in quality sensor has determined that the air quality is good and

that the air does not need to be cleaned anymore. When the air quality

deteriorates, the appliance starts running at a low fan speed and noise

level so that the energy consumption is minimised.

The appliance does not

work. Fan speed lights 1, 2

and 3 flash, all other lights

are out.

This is a component defect. Contact the Consumer Care Centre in your

country (you find its phone number in the worldwide guarantee leaflet). If

there is no Consumer Care Centre in your country, go to your local Philips

dealer.

The appliance does not

work. Fan speed lights 1

and 2 flash, all other lights

are out.

This is a component defect. Contact the Consumer Care Centre in your

country (you find its phone number in the worldwide guarantee leaflet). If

there is no Consumer Care Centre in your country, go to your local Philips

dealer.

AC4074: The appliance

does not work. The air

quality light ring flashes

This is air particle sensor error or an air particle sensor and gas sensor

error. Contact the Consumer Care Centre in your country (you find

its phone number in the worldwide guarantee leaflet). If there is no

Consumer Care Centre in your country, go to your local Philips dealer.

AC4074: The air quality

light ring keeps flashing

purple.

This is a gas sensor error. Switch off the appliance and unplug it. Take the

appliance to your Philips dealer or an authorised Philips service centre.
