Quick Test Mode:
Note: This test erases all faults and memory
:
To enter press Soil, Signal, & 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.
3. After the displaying the software version, turn
Jog dial CCW until version disappears.
Press Spin to test Door Lock/Unlock circuit.
Press Temp Key (with door locked) to cycle through
the Water Valves circuit test in this order: Pre, Bleach,
Cold Main, Hot, Boot valve, then off.
Press Soil Key to test the Heater
Press Signal Key to test the Pump
Service Mode:
This mode allows more detailed operation tests and
troubleshooting, to enter press Signal & Delay Start
simultaneously with the power on.
While in Service Mode (the Service Mode can be entered
while the unit is in a wash cycle) the following tests can
be performed:
Quick Spin Test = Delay Start & Pre Wash: This acceler-
ates the drum motor from 0 to maximum RPM over a few
minutes. Press the Start/Pause button during the test to hold
its spinning speed up to 10 min. before going back to Quick
Spin Test Mode, return to spin with Delay Start & Pre Wash.
Cycle Count = Press the Signal button to see how many
times the unit was used.
Soft Ware # = Press the Soil Level button to see the software
version information
Fault Code Test = Press the Pure Cycle 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, push Start/Pause again to get
back to faults)
Peripheral (Main PCB) input Tests, enter Service Mode &
press Spin key.
1. Turn the Dial so that the Extra Rinse LED is turned on.
Next, press the Start/Pause Key. Temperature will be dis-
played in Fahrenheit.
2. Turn the Dial so that the Cold/Cold LED is turned on. Next,
press the Start/Pause Key. The door switch status will be dis-
played (CL if Closed, OP if Open).
3. Turn the Dial so that the No Spin 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. Turn the Dial so that the Light LED is turned on. Next,
press the Start/Pause Key. The Water Frequency will be dis-

Spin Only option:
Power on, Press and hold Spin until display changes.
Press Spin to select spin time.
Press Start/Pause to start cycle, Normal Cycle 10/12
minutes, Heavy Duty Cycle 11/13 minutes, Delicate
Cycle 8 minute. Spin speed varies with cycle.
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
Fabric Softener Dispenser Test:
Start Rinse and Spin Cycle. After fill is completed
remove detergent drawer, place towel below opening
and within 3 minutes the dispenser will activate
