When the hose of your Philips Stand Garment Steamer forms a U-shape, condensation in it cannot flow back into the water tank, and this can cause the head of the garment steamer to drip water.
In this case, lift the head of your stand steamer up to straighten the hose vertically. In this way, condensation can flow back into the tank.
At the start of a steaming session, set the steam setting to be in MAX mode. After this, hold the steamer head away from the garment and press the steam trigger for 10 seconds to release the initial gush of water droplets.
