Make sure the keeping-warm plate (14) and the bottom of the glass jar (1) are dry before starting brewing.
Water steam escapes during brewing. Keep sufficient distance to shelves, walls, and persons. There is a risk of scalding!
The keeping-warm plate and the glass jar become very hot during use.
Never leave the glass jar empty on the heated plate. Risk of fracture!
- Open the lid (9) of the water tank and fill the water tank (10) with water until the Max 1.5L marking. This marking must not be exceeded.
