Test Check Correction
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.
1. Remove the door lock assembly and
measure the resistance of the PTC.
1. Disconnecttheplugfromthedrivemotorand
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
1topin2,pin1topin3,pin2topin3)All
reading 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. Disconnecttheplugfromthedrivemotorand
measure the resistance pins 4 & 5 in the
motor.
4. Disconnect the plug from the motor and
measure the resistance of the windings (pin
1to2,pin1to3,pin2to3).Allreadings
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 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 the ground
and both heater terminals. It should be
open when heater terminals are
disconnected.
1. Check the resistance of the tub in NTC. If Is
it around 4.8 K Ohms?
1. Check the wiring harness between the
control board & the interface board.

No. Close the door.
Yes . Go the s tep (2).
Open. Check the door strike. If good, replace
the door switch assembly.
Closed. Replace the control board.

Around 1500 Ohms. Defective control board.
If the reading is between 105 & 130 Ohms, replace
the speed control board.
If the meter reads not than between 105 & 130
Ohms, replace the motor.
No. Replace the motor.
Yes . G o to step (3)
No. Check the tub bearings.
Yes . G o to step (3)
If readings are correct, replace speed control board.
If the readings are incorrect, replace the motor.
No. Replace the motor.
Yes . G o to step (3)
No. Check the tub bearings.
Yes . G o to step (3)
If the meter reads not other than between 105 & 130
Ohms, replace the motor.
If reading is between 105 & 130 Ohms, go to
step (4).
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, replaced the heating
element.
No, replace the heater assembly.
Yes , chec k t he wir ing.
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 control board.
Note: If only one of the LEDs will not light, replace
the interface board
If readings are correct, replace speed control board.
