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.

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 3 and 6 Ohms.
Test 10:
1. Communication problem. Check the wiring between
the main control board and the motor control board.
1. Communication problem. Check the wiring between
Test 11:
the main control board and the user interface board.
Test 12:
1. Have the power company check the frequency and
voltage of the incoming power.
Test 13:
1. Check the resistance of the heating element. It
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.
1. Check the resistance of the drum water NTC. Is it
Test 14:
around 4.8K ohms?
1. Check wiring between the main control board and
Test 15:
motor control board.
1. Check wiring between main board and pump
Test 16:
2. Check wiring between main control and recirculation
board.
3. Check pump for open coil (resistance check).
Test 17:
1. Unplug the unit for 1 min. and retry.

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.
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 OK, then go to step (2).
If OK, then go to step (3).
If OK, then replace main control.
If problem is not corrected replace main control.
