The wash water level is approximately 1.86
inches deep at the bottom center of the wash
basket.
The drain pump will be activated when the
main PC board detects frequency under 36 Hz.
(Flood Protection). In flood protection mode, the
pump will run until reset level is reached. Flood
protection is active even in the idle mode, as long
as the door is closed.
Operation of the water level sensor can be
checked by using Service Mode test 10. (See
the
Service Mode Test
in the
Diagnostics and
Service Information
section of this service
guide.)
Specific failures associated with the water level
sensor can initiate fault codes 6, 8, 20, 25, and
65 (see the
Fault Codes
section in this service
guide).
The water level sensor is located on the Main
Board, top right side of the cabinet.
The water level sensor is located on the main
board. It is connected by a hose to an air
chamber near the bottom of the outer tub and
operates by a DC voltage signal to the board.
The voltage is monitored by the Main Board,
which turns off the water valves when the desired
water level is achieved.
Sensor output voltage can be read from the
pressure sensor between pins 3 and 4. If shorted
between pin 2 and pin 3, it will cause the board to
shut down. The board will come back on.
When the water level rises in the washer tub, air
is trapped in the air chamber located on the rear
of the tub near the bottom.
As the water level rises, the air pressure in the air
chamber increases. The pressure is translated
into a DC voltage signal by the water level sensor.
The DC voltage will vary, depending upon water
level.
