FOR SERVICE TECHNICIAN ONLY - DO NOT REMOVE OR DESTROY
Be sure to perform the Diagnostic Tests before replacing the
system components.
Pump Motor Continuity Test

1 to 2 Normal = approx. 12.3 Ω
Abnormal = Infinity
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:

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.

Manually Unlocking the Door Lock System
1. Unplug washer or disconnect power.
2. Remove the lower kick panel.
3. Reach up along the inside of the front and locate the bottom
of the door switch/lock mechanism.
4. Located on the bottom of the door switch/lock mechanism
is a tear-drop shaped tab.
5. Gently pull the tab down about 1/4" (6 mm) or until a click is
heard.
6. The door may be opened.
ELECTRONIC ASSEMBLIES -
REMOVAL OR REPLACEMENT
IMPORTANT: Electrostatic (static electricity) discharge may cause
damage to electronic control assemblies. See page 1 for details.
NOTE: Be sure to perform the Diagnostic Tests before replacing the
control board.
**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.
