Quick Test Mode
Note: This test erases all faults and memory:
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, turn the Jog-Dial
so that the version disappears. Press the following
keys to test the various components
Press Temp Key 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 Spin Key to test Door Lock/Unlock circuit.
Press Soil Level to test Heater.
Press Signal Key to test the Water/Steam Heater.
Press Steam Key to test the Pump
When either Test or Spin is displayed on the LCD,
press Start/Pause key to conduct the motor test.
In Test mode, you can test the clockwise and counter-
clockwise movement of the motor. However, the water
level must satisfy the heater water level (24300) to en-
ter Test mode.
In Spin mode, you can test the motor at a high rpm.
Service Mode:
This mode allows more detailed operation tests and trouble-
shooting, 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 & Activ Fresh: This acceler-
ates the drum motor from 0 to maximum RPM over a few
minutes. Note: Stay with the washer during this test, out of
balance detection is bypassed and the door may not lock.
Press the Start/Pause button during the test to hold spin 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 the Soil button to see the software version
information
Fast Time Down = Press the Temp button to advance to the
next cycle
Fault Code Test = Press the Steam button 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)
Peripheral (Main PCB) input Tests
1. Select My Cycle. Then turn the Jog-Dial so that the Extra
Rinse LED is turned on. Next, press the Start/Pause Key. The
Water Temperature will be displayed in Fahrenheit.
2. Select My Cycle. Then turn the Jog-Dial so that the Extended
Spin LED is turned on. Next, press the Start/Pause Key. The
door status will be displayed (OP if open, CL if closed).
3. Select My Cycle. Then turn the Jog-Dial so that the Delay
Start LED is turned on. Next, press the Start/Pause Key. The
door lock Switch status will be displayed (UL if unlocked, Lo if
locked).
4. Water Frequency/Water Sensor Testing - Select a cycle &
start the washer, enter Service Mode & press My Cycle. Turn
the Dial so that the Steam LED is turned on. Next, press the
Start/Pause Key. The Water Frequency will be displayed. The
frequency will change as the unit fills.
5. Select My Cycle. Then turn the Jog-Dial so that Signal LED is
turned on. Next, press the Start/Pause Key. The AG Kit status
will be displayed after 3 seconds. (―ㅂE‖ if the AG kit is abnor-
mal. ―—‖ if the AG Kit is working properly)
