Be sure to perform the Diagnostic Tests before replacing the
system components.
Washer Pump Motor Continuity Test
Pins
1 to 2
Washer Motor Continuity Test
1. Unplug washer or disconnect power.
2. Disconnect the wire harness from the motor and measure the
resistance of the motor. Use the following table:
Pins
1 to 2
2 to 3
1 to 3
Transformer Connector
Primary 30–35 ohms
Blue to blue 1 ohm
White to white 2 ohms
Yellow to blue 0.5 ohms
Red to red 11 ohms
Water Temperature Sensor
1. Unplug washer or disconnect power.
2. Disconnect the wire harness from the water temperature sensor
and measure the resistance of the sensor. Use the following table.
An abnormal condition is an open circuit. This reading can be
taken from the cable attached to the CCU terminal SET2.
Temperature
32°F (0°C)
86°F (30°C)
104°F (40°C)
122°F (50°C)
140°F (60°C)
158°F (71°C)
203°F (96°C)
Results
Normal = approx. 12.3 Ω
Abnormal = Infinity

**The number 1 pin has been marked on the bottom part of the connector.
**An infinity measurement occurs when the multimeter does not detect an ohm reading.
Manually Unlocking the Door Lock System
1. Unplug washer or disconnect power.
2. Remove the toe kick panel.
3. Reach up along the inside of the front and locate the bottom
of the latch assembly.
4. At the bottom of the latch assembly is a tear-drop shaped tab.
5. Gently pull the tab down about 1/4" (6 mm) or until a click is heard.
