1. Unplug power cord.
2. Remove rear panel.
3. Remove Washer Top.
4. Remove Main PCB Assembly cover as shown in Figure below.
5. Locate the white Hall Sensor 4 wire connector using wiring diagram wire colors

as your guide.

6. Plug in power cord, close door, and press power button. DO NOT PRESS

START!

7. Place meter leads on White & Gray wires. You should read 10 to 15 Vdc output

from the Main PCB Assembly to the Hall sensor. If no 10 to 15 Vdc is
measured the control board is defective.

8. Place meters leads on Blue to Gray. Turn motor rotor slowly by hand. You

should measure a pulsing 10 Vdc. Place meter leads on Red to Gray. Turn
motor rotor slowly by hand. You should measure a pulsing 10 Vdc. If both tests
measure a pulsing 10 Vdc, hall sensor and harness OK. If either or both tests
measures 9 to 10 volts, but does not pulse or change, Hall sensor has failed
and must be replaced. IF zero (0) voltage is measured on either test, check red
& blue wires for continuity. Repair or replace harness as needed.

7. To measure output signal voltage from the hall sensor, carefully move test

leads to terminals 1 to 4, blue and gray. Slowly rotate motor rotor by hand. 
You should read a pulsing 10 Vdc. If 10 Vdc is measured from 1 to 4, move
lead on blue wire to red wire, terminal 2. Repeat rotating motor rotor by hand.
You should read a pulsing 10 Vdc from red to gray.

8. If pulsing 10 Vdc is measured from 1 to 4 and 2 to 4, hall sensor is OK! If either

test netted only 9 to 10 Vdc without changing (no pulsing) the hall sensor is
likely defective. Disconnect power by unplugging washer and ohm check hall
sensor to verify failure of the hall sensor.

9-5. INLET VALVE ASSEMBLY

Depending on the cycle and water temperature, the controller will energize the hot or cold
water valve solenoids to meet the selected water temperature.

After pull out the connector of defective valve, check the resistance.

9-6. HEATER ASSEMBLY

1. The Wash Heater is designed to raise the wash water to the desired temperature

selection during certain wash cycles.

2. The Steam generator heater is designed to make the water to the steam during

steam cycles. 

* Each circuits of loads in wiring diagram are all same.
