I do not see water vapour coming out of the appliance. Is it working?

I want to check whether the air humidity sensor works or not.

The appliance produces a strange smell.

You forgot to put the humidification filter in the water tank. Make sure the humidification filter is in the water tank.

The humidification filter is too dirty to function properly. Rinse and/or descale the humidifiation filter (see chapter ‘Cleaning and maintenance’, section ‘Cleaning the humidifcation filter’).

The room in which you are using the appliance is bigger than 40 square metres.The appliance works optimally in a room with a maximum size of 40 square metres.

The white deposits are called scale and they consist of minerals from the water.  Scale on the humidification filter affects the humidifying performance. Therefore you have to descale the humidification filter when the first speed light (with the indication CLEAN 1/5 above it) flashes. Follow the instructions in chapter ‘Cleaning and maintenance’, section ‘Descaling to clean the humidification filter’.

The air quality sensor is dirty. Clean the air quality sensor.

When water vapour is very fine, it is invisible.This appliance has a specially designed humidifcation filter that produces very fine water vapour.Therefore you cannot see the water vapour.

Remove the cover of the air quality/humidity sensors and then gently blow moist air into the opening. After a while, the CURRENT HUMIDITY indication changes. Note that if the initial CURRENT HUMIDITY indication is already 60%, the indication cannot show an even higher humidity when you blow moist air towards the sensor.

The first few times you use the appliance, it may produce a plastic smell. This is normal. Howeve, if the appliance produces a burnt smell, contact your Philips dealer or an authorised Philips service centre.The appliance may also produce an unpleasant smell when one of the filters is dirty. In this case, clean or replace the filter concerned.
