Hi, recently I bought Steamer 1. It is stated in the manual that, when turned on, red light shall turn off and the green light shall come on. But in my Steamer green light does not come. I see red light on and then it turns off. No green light. It looks like the device is operational - I see the steam. But is it working properly?? It is my first Steamer from Steamery and I have nothing to compare it with. How can I be sure that the device is working properly if the green light does not come? Thank you. -Elena.
