2.1 Float Switch B8
A float switch (B8) is located in the bottom pan of the appliance housing.
If water leaks into the bottom pan, float switch B8 is activated.
The program and water intake are stopped, and the fault message
Waterproof is issued.
2.2 Hot-Water Intake Control
The hot-water intake starts from a temperature selection of
86°F (30°C) in US models, in all wash programs except woolens, silk and
hand wash.
2.3 Automatic Load Control/Intelligent Water Intake (IWE)
Automatic load control matches the incoming water amount to the amount of
laundry.
Automatic load control is the outcome of intelligent water intake (IWE).
An imbalance sensor monitors the water intake. The control measures the
absorbency rate of the laundry based on the first and second water intake,
the pressure drop rates, the spin speed variance and the water amount taken
in.
Based on this input, the laundry load and type of laundry are calculated.
Depending on program, the following parameters are adjusted:

Water level,

Wash duration (includes correction of residual time),

Number of additional heating cycles,

Number of rinses,

Water level in the rinse cycles,

Rinse duration,

Final spin speed.
