The first time you use your garment steamer, it might not produce steam right away as there is no water in the system yet. Don't worry; this is normal and will only happen the first time you use it.
Please press the steam trigger for one minute. This will promote water circulation and the production of steam.
The following applies to model GC62x:
During start-up: If the power button is flashing, wait for 90 seconds for the steamer to heat up. You can then press the steam trigger.
During steaming: If the power button is flashing, the steamer has switched to the auto shut-off mode. Press the power button to get the steamer to heat up again. Once it has heated up, press the steam trigger.
