Red light on the handle: the automatic shut-off function is on
Your iron (model with dial) is designed to automatically shut off after 30 seconds in horizontal position and after 8 minutes in vertical position. When this automatic shut-off function is activated, a red light will blink on your iron’s handle.
To solve this, pick the iron up or move it slightly. This will deactivate the automatic shut-off function and then the red light will stop blinking.
Red (or amber) light below the handle: heating up
When your Philips Iron (model with dial) is heating up, a red or amber light will blink under its handle. This is normal.
It will stop blinking when the iron has reached the requested temperature.
