Problem
I cannot change
the sensitive shave
settings on the
shaver.
The shaver does not
shave as well as it
used to.
The shaver does not
work when I press
the on/off button.
Possible cause
The shaving heads
are damaged or
worn.
Hairs or dirt obstruct
the shaving heads.
The shaver is still
attached to the wall
socket. For safety
reasons, the shaver
can only be used
without cord.
The rechargeable
battery is empty.
The travel lock is
activated.
The shaving unit is
soiled or damaged to
such an extent that
the motor cannot run.
