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. The unit displays the software version for a
second then clears the EEprom.
3. After the displaying the software version, LCD
will display Model information. If EEEE is displayed
the PCB ass’y is defective.
4. When the version is displayed. Press the following keys to test the various components
Press Temp Key to cycle through the Water Valves in
this order: Pre Cold, Cold Main, Bleach, Cold Main &
Bleach for Fabric Softener, Hot, then off.
Press Spin Key to test Motor circuit.
Press Signal Key to test Drain Pump
Press Soil to test door lock - unlock circuit
Service Mode:
This mode allows more detailed operation tests and
troubleshooting, to enter press Signal & Extra
Rinse simultaneously with the power on.
While in Service Mode the following tests can
be performed:
Quick Spin Test = Delay Start & Silver Care:
This accelerates the drum motor from 0 to maximum RPM over a few minutes. Note: Stay with the
washer during this test, out of balance detection
may be bypassed. Press the Start/Pause button dur-
ing the test to hold its spinning speed for 10 minutes
before going back to Quick Spin Test Mode.
Cycle Count = Press the Signal button to see how many times
the unit was used
Soft Ware # = Press Soil button shows software version
Fast Time Down = Press Temp button to advance to next cycle
Fault Code Test = Press the Silver Care button to view the stored
fault codes – then turn Dial to view error codes (Push Start/Pause
while the code is displayed to view the number of cycles since the
error occurred)
Peripheral (Main PCB) input Tests
1. Extra Wash. Then turn the Dial so that the Normal is turned on.
Next, press the Start/Pause Key. The Water Temperature will be
displayed in Fahrenheit.
2. Extra Wash. Then turn the Dial so that the Whites is turned on.
Next, press the Start/Pause Key. The door status will be displayed
(OP if open, CL if closed).
3. Extra Wash. Then turn the Dial so that the Perm Press is
turned on. Next, press the Start/Pause Key. The door lock Switch
status will be displayed (UL if unlocked, Lo if locked).
4. Extra Wash. Then turn the Dial so that the Delicate/Hand
Wash is turned on. Next, press the Start/Pause Key. ― ‾0 ‖ will illu-
minate if below level, ― ‾1 ‖ if above level (Overflow).
5. Extra Wash. Then turn the Dial so that the Wool is turned on.
Next, press the Start/Pause Key. ― -0‖ will illuminate if below level,
―-1‖ if above level (Heater-On).
6. Extra Wash. Then turn the Dial so that the Quick Wash is
turned on. Next, press the Start/Pause Key. ―_0‖ will illuminate if
below level (Reset), ―_1‖ if above level.
7. Extra Wash. Then turn the Dial so that the Towels is turned on.
Next, press the Start/Pause Key. The Water Frequency will be
displayed.
8. Extra Wash. Then turn the Dial so that the Rinse+Spin is
Turned on. Next, press the Start/Pause Key. Then, it will display
the Ag Kit Status in 3 seconds: ―- -‖ if AG kit is operated properly.
―7E‖ if AG kit is out of order (check wire harness & PCB)
9. Extra Wash. Then turn the Dial so that the Spin Only is turned
on. Next, press the Start/Pause Key. Then, it will display the
MEMS Sensor Kit status after displaying ―00‖ for 3 seconds:
―- -‖ if MEMS Sensor kit is operated properly. ―8E‖ if MEMS Sensor
kit is out of order (check wire harness & PCB)

EEPROM Clear Check
Power off, Press Delay Start, Signal and Power Key at the same time. Good = Good Fail = FAiL. All memory will be
cleared, including Fault Codes. This should be done when a new Main PCB is installed
