Problem Possible Cause Solution
I cannot fully attach
the brush head. There
is a gap between the
brush head and
handle. This gap is normal and is
needed for the brush
head to vibrate
appropriately.
My Philips Sonicare
toothbrush vibration is
less powerful than
before. The adaptive
intensity function has
been activated, the
pressure sensor has
been activated (see
'Pressure Sensor
Feedback'), or the
intensity was
accidentally changed. Turn off the adaptive
intensity and/or the
pressure sensor function
(see 'Activating or
deactivating features'),
and/or raise the
intensity level by
pressing the intensity
indicator light to the
desired level (see
'Intensity settings').
My Philips Sonicare
toothbrush is missing
parts. The missing parts are
not included with the
model you
purchased. The accessories and the
number of brush head
attachments are
dependent on the
model number you have
purchased. You can find
the HX model number at
the bottom of your
handle to identify what
comes with your handle.
