When the Calc-Clean or Decalc light of your Philips Steam Iron is blinking as in the image below, it is time to descale it.

If the alert remains, this means that the descaling process has not been performed properly.  Please click here to follow the descaling steps on the website.

After performing all of these steps, if the descaling alert continues to blink, bring the steam iron to a Philips centre for a check-up.
