Test
Test 5: 1. Is the water level above 4.5 inches?
2. Does water enter the washer continuously.
3. Remove power from washer. Does the water
stop coming in?
4. Replace the pressure sensor switch. Did this
correct the problem?
Test 6: 1. Is the loading door closed?
2. Disconnect the plug from J2 on the control
board and check for continuity between the
pins in the plug.
Test 7: 1. Start the diagnostic test. Turn the program knob 8
clicks clockwise from the start position.
Test 8: 1. Disconnect the plug from the drive motor and
measure the resistance pins 4 & 5 in the motor.
Test 9: 1. Remove the belt from the motor and spin the
motor pulley. Does the motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the motor and
measure the resistance of the windings (pin
1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All
readings should be between 4 and 6 Ohms.
Test 10: 1. Remove the belt from the motor and spin the
motor pulley. Does the motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the drive motor and
measure the resistance between pins 4 & 5
in the motor.
4. Disconnect the plug from the motor and
measure the resistance of the windings (pin
1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All
readings should be between 4 and 6 Ohms.
Test 11: 1. Communication problem. Check the wiring
between the control board and the speed
control board.
Test 12: 1. Check the resistance of the NTC. Is it
around 50K ohms?
Test 13: 1. Have the power company check the
frequency of the incoming power. If correct,
replace the control board.
