Possible solution
The first few times you use the appliance, it may produce
a plastic smell. This is normal. However, if the appliance
produces a burnt smell even if removing filters, contact your
Philips dealer or an authorized Philips service center. The
appliance may also produce an unpleasant smell when the
filter is dirty. In this case, clean or replace the filter concerned.
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 sleep mode.
Perhaps you did not reset the filter lifetime counter. Plug in the
appliance, touch to switch on the appliance, and touch and
hold the reset button
The hall sensor is not working properly. Remove and then
reattach the front panel. If the error code "Er" still exists,
contact the Consumer Care Center in your country.
