This problem may be due to below 3 scenarios:
1.You do not plug in the appliance and switch ON. Ensure that the appliance is switched ON during calc-clean.
2.You have not pressed the Calc clean button for 2 seconds until the appliance started beeping.
3.The water tank is empty. Fill the water tank halfway.
If this does not resolve your issue, please contact the Philips Consumer Care Center in your country. You find its phone number in the worldwide guarantee leaflet, or Philips on line support page.
