Why The Kettle "Leaks" Water?
Steam Tube
1.Steam Tube: After the water reaches the boiling point, a lot of
steam produced in the kettle gets into the stainless steel tube and
heats the temperature controller to switch off the kettle automatically.
0.9 L
2.If the water exceeded the max line, it is possible for the boiling
water to jump into the steam tube, which explains why it "leaks"
from the bottom. It is not recommended to add the water exceeding
the max line.
