4. Lift the dispenser from the component tray.
5. Remove the 2 Phillips-head screws that attach
the dispenser inlet to the dispenser.
6. Lift the dispenser inlet out of the dispenser.
Note: Pink plastic pressure fi ttings are used on
the dispenser inlet for a tight fi t and to reduce the
possibility of leaks.

Pressure Sensor

The pressure sensor is connected by a clear
pressure hose to an air reservoir near the bottom
of the outer tub and operates by a frequency (kHz)
signal to the power board.
• When the water level rises in the washer tub,
air is trapped in the reservoir. As the water level
rises, the air pressure in the reservoir increases.
• The pressure is translated into an electrical
signal (frequency) by the pressure sensor.
• The frequency will vary from approximately 27
kHz (empty tub) to 21 kHz (full tub).
• This frequency can be measured at the pressure
sensor between the purple and orange wires.
To remove the pressure sensor:
1. Place the control panel in the service position.
