1. Disconnect the plug from the drive motor and
measure the resistance pins 4 & 5 in the motor.
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.
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.
1. Communication problem. Check the wiring between
the control board and the speed control board.
1. Check the resistance of the water valve NTC. Is it
around 50K ohms?
1. Have the power company check the frequency of
the incoming power. If correct, replace the control
board.
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 tub NTC. Is it around
4.8K ohms?
1. Check the wiring harness between the console
control board & the interface board.

If the reading is between 80 & 130 Ohms, replace the speed
control board.
If the meter reads other than between 80 & 130 Ohms,
replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the readings are correct, replace the speed control board.
If the readings are incorrect, replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the meter reads other than between 80 & 130 Ohms,
replace the motor.
If the reading is between 80 & 130 Ohms, Go to step (4)
If the readings are correct, replace the speed control board.
If the readings are incorrect, replace the motor.
Wiring bad. Correct wiring problem.
Wiring good. Replace the control board. If the problem is not
corrected, replace the speed control board.
No. Replace the water inlet valve assembly
Yes. Replace the control board.
If the readings are incorrect, replace the heating element.
No, replace the heater assembly.
Yes, check the wiring - if good, rpl console control board.
If defective, correct wiring problem.
If the harness is good and none of the LEDs light, replace the
interface board. If this does not correct the problem, replace
the console control board.
Note: If only one of the LEDs will not light, replace the interface
board.
