Quick Test Mode
To enter press Spin, Soil, & Power simultaneously with the power
off.
1. All LED’s light up and the washer beeps as it
enters the Quick Test Mode.
2. After the displaying the software version, LCD
will display Model information. If EEEE is displayed the PCB ass’y is
defective.
3. When the version is displayed, turn the Jog-Dial CCW so that the
version disappears. Press the following keys to test the various
components:
Press Temp to cycle through the Water Valves circuit test (lock the door
first) in this order: Pre-Wash, Bleach, Cold Main, Hot, & Steam, then off.
Press My Cycle to test Door Lock/Unlock circuit
Press Spin to test Circulation/Drain Pump.
Press Soil to test the Water/Steam Heater.
When either Test or Spin is displayed on the LCD, press Start/Pause
to conduct the motor test.
In Test mode, you can test the clockwise and counterclockwise
movement of the motor.
In Spin mode, you can test the motor at a high rpm.
Service Mode:
This mode allows more detailed operation tests and
troubleshooting, to enter press Delay Start & Pre Soak
simultaneously with the power on.
In Service Mode the following tests can be performed:
Quick Spin Test: Press and hold Delay Start & Softener Option.
Note: This accelerates the drum motor from 0 to max RPM in a
few minutes. Stay with the washer during this test, out of balance
detection may be bypassed. Press Start/Pause during the test to
hold spinning speed for 10 minutes before going back to Quick Spin
Test Mode. Press and hold the Delay Start & Softener Option to
continue.
Cycle Count = Press Pre Soak to see how many times the unit was
used.
Software # = Press Soil level to see the SW version information.
Fault Code Test = Press Spin to view the stored fault codes – then
turn Jog Dial to view error codes. Push Start/Pause while the code is
displayed to view the number of cycles since the error occurred, Push
Start/Pause to go back to faults.
Peripheral (Main PCB) input Tests:
1. Select Eco Plus. Then turn the Jog-Dial so that the Perm Press
LED is turned on. Next, press Start/Pause and Water Temperature
will be displayed in Fahrenheit.
2. Select Eco Plus. Then turn Jog-Dial so that the Delicates/Hand
Wash LED is turned on. The door status will be displayed (OP if open,
CL if closed).
3. Select Eco Plus. Then turn Jog-Dial so that the Quick Wash LED
is turned on. The door lock Switch status is be displayed (UL =
unlocked, Lo = locked).
4. Select Eco Plus. Then turn Jog-Dial so that the Pure Cycle LED is
turned on and Water Level Frequency will be displayed.
EEPROM Clear Entering Quick Test Mode will clear
EEPROM
Caution: Error codes must be retrieved from Service Mode
BEFORE entering the Quick Test mode or else they will be deleted
