Test
1. Find out if the unit was overloaded. If not, remove
Test 8:
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 3 and 6 Ohms.

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 3 and 6 Ohms.

should be approximately 14 ohms.
2. Check the resistance between ground and both
heater terminals. It should be open when the heater
terminals are disconnected.

Correction
No. Replace the motor.
Yes. Go to step (2)
No. Check the tub bearings.
Yes. Go to step (3)
If the readings are correct, check wiring from motor to
motor control board, If good, replace the motor control
board.If the readings are incorrect, replace the motor.
No. Replace the motor.
Yes. Go to step (2)
No. Check the tub bearings.
Yes. Go to step (3)
If the meter reads other than between 105 & 130 Ohms,
replace the motor. If the reading is between 105 & 130
Ohms, Go to step (4)
If the readings are correct, replace the motor control
board. If the readings are incorrect, replace the motor.
Wiring bad, correct wiring problem.Wiring good, replace
the main control board. If the problem is not corrected,
replace the motor control board.
Wiring bad. Correct wiring problem. Wiring good.
Replace the user interface board. If the problem is not
corrected, replace the main control board.
No. Replace the water inlet valve assembly
Yes. Replace the control board.
If correct, for error code E5C, replace the motor control
board. If correct, for error codes EA1, EA2, EA3, EAE or
EA5, replace the main control board
If the readings are incorrect, replace the heating element.
If the readings are incorrect, replace the heating
element.If the problem is not corrected, replace the main
control board.
No, replace the heating element.
Yes, check the wiring.
If good, replace the motor control board.
If problem is not corrected replace main control.
