Water Level Senser
The water level senser is installed on the cabinet
right side top brace. The water level senser is
connected by a hose to an air chamber attached to
the bottom of the outer tub. The water level control
consists of
one internal senser that monitor water
level conditions.
When the water level rises in the outer tub, air is
trapped in the air chamber.
As the water level rises, the air pressure in the
air chamber increases.
The increased pressure operates the water
senser.
The washer has over fl ow protection and will
automatically pump out regardless of whether
the washer is on or off, as long as the unit is
plugged in. This action supersedes all other
commands.
The increased pressure will lead to the water
senser output different frequency. Different
frequency match the different water level. The
4 water level conditions monitored are empty,
foam, main, and overflow.

Water Level Control Operation
When the machine is empty, there is no water in the
outer tub and no pressure in the air chamber, the
sensor will output the empty frequency signal. As the
water level rises, the air pressure in the air chamber
increases, the water sensor frequency will change as
the pressure change until the foam level reach, the
tumble begins. Water temperature is read by the
thermistor and fill valve percentage of operation
(water tempering) is calculated for the main wash.
When calculated, and/or when the load absorbs
water, the tumbling will pause. Fill will continue until
the main water level is reached (Adaptive fill), the
water sensor output main level frequency signal,
and main wash tumbling begins.
Water Levels
The foam water level is approximately
3
inches
below the door opening and approximately
1.25
inch
deep at the bottom rear of the wash basket.
Foam Water Level
Main Water Level
The main water level is approximately
2.4
inches
below the door opening and approximately
1.85
inches deep at the bottom rear of the wash
basket.
