There are deposits or descaling tablet residues in the boiler.
Water drops that cannot be evaporated form in the iron.
How to rinse the iron:
Provide a pot or other metal container with a capacity of 1.5–2 L.
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 that steam is available.
Place the iron on the pot or metal container in such a way that the steam openings of the iron are unobstructed.
Push the slider for continuous steam.
The steam ironing system then turns off automatically after 3 minutes if the iron is not moved.
The steam ironing system can then be used again as normal.
