What is the “standby” or “sleep” mode on my Chief Steamer 100?

The standby mode is a safety feature now mandated for European appliances like steamers. If the machine is left unattended for 30 minutes, it will go into this mode, turning off the heater for safety and energy-saving. The green light will blink slowly during this mode. To reactivate the machine, press the steam trigger switch or turn the power switch off and on.
