4. Remove the dispenser from the front and left
side braces.
5. Tilt the dispenser clockwise and remove the
outlet hose:
a. Squeeze the clamp and slide it back.
b. If necessary, carefully break the hose loose
by inserting a small fl at blade screwdriver
under the hose to break the seal.
c. Remove the hose.
Note: Install dispenser outlet hose with notch cutout
engaged with notch on the dispenser body.

Water Level Sensor
The water level sensor is connected by a hose to an
air chamber near the bottom of the outer tub and
operates by a frequency (kHz) signal to the main
PCB.
Sensor Hose
The frequency is monitored by the main PCB, which
turns off the water valves when the desired water
level is achieved.
The water level sensor wires (orange, pink and
yellow) are connected at pins 9, 8, and 6 at the 4-pin
red connector CN11 on the main PCB. (See
).
Board Connections
The approximate resistance value of the transducer,
measured between the pink and orange wires, is
23.6 Ω.
• When the water level rises in the washer tub,
air is trapped in the air chamber. As the water
level rises, the air pressure in the air chamber
increases.
• The pressure is translated into an electrical
signal (frequency) by the water level sensor.
• The frequency will vary, depending upon water
level, from approximately 26 kHz (empty tub),
25.3 kHz (reset level), 24.8 kHz (heater safety
level), 24.2 kHz (wash level), to 22 kHz (overfl ow
level).
• This frequency can be measured at the water
level sensor between the pink and yellow wires.
