Philips GC4890/02 Manual page 17

Problem
The red light flashes
(specific types only).
The iron makes a
humming sound.
The humming sound
stops, although the
Ionic DeepSteam
function is on.
Possible cause
The automatic shut-off
function has switched off the
iron (see chapter 'Features',
section 'Automatic shut-off
function').
The Ionic DeepSteam
function is on.
The sound stopped because
you placed the iron on its
heel.
Solution
Move the iron slightly to deactivate the
automatic shut-off function. The red auto-off
light goes out.
If you hear the humming sound when you iron
without steam, press the Ionic DeepSteam
button to switch off the Ionic DeepSteam
function. The Ionic DeepSteam function has no
effect when you iron without steam.
The humming sound resumes as soon as you
continue to iron.
