When you press your iron’s steam button for the first time (after filling the appliance with water), you will experience a steam delay of 30 seconds. During these 30 seconds, you will hear a pumping sound (which you will also hear during normal use).
After this start-up cycle, the iron will generate steam when you press the steam button.
Please note: for PerfectCare AquaPro steam generator irons this delay could take up to a few minutes. This could happen when the iron was stored for a long time.
