There are deposits or descaling tablet residues inside the boiler.
Water droplets form inside the iron that cannot be vaporised.
How to rinse the iron:
Have a pot or other metal container with a capacity of 1.5–2 l on hand.
Fill the water container and switch on the steam ironing system.
Set the temperature selector to 0 and wait until the steam ironing system indicates the “steam ready” state.
Place the iron on the pot or metal container in such a way that the steam openings of the iron are unobstructed.
Move the slider for continuous steam.
The steam ironing system switches off automatically after 3 minutes if the iron is not moved.
Subsequently, you can use the steam ironing system as normal.
