Ƀ Where XX.YY.ZZ corresponds to the 3 sets of 2 digit numbers that
describe a software version and PN1.PN2.PN3.PN4.PN5.PN6.PN7.PN8
is the 8 digit settings file part number.
Ƀ The ACU, HMI and Settings file information will be displayed in the LEDs
(SENSE, SOAK, WASH, and DONE) in binary format. Consider SENSE
LED the most significant bit.
Ƀ The identifier value of the component information will be displayed in
LED Group1/TEMPERATURE Group in binary format. Consider HOT LED
from top as the most significant bit. (For Example: Cold LED blinks, then
the Identifier is 1. Cold and Cool LED blinks, then the Identifier is 3).

Ƀ Fault codes are composed by a F# and an E#. The F# has two digits
and indicates the suspect System/Category. The E# has two digits and
indicates the suspect Component system.
Ƀ The fault codes are displayed in binary format at the LEDs (SENSE,
SOAK, WASH, and DONE). When the LED is ON it represents a binary 1
and when the LED is OFF it represents a binary 0.
Refer to "Reading Binary Codes".
Ƀ When the F# digits are displayed, the LID LOCK LED will be turned ON.
Ƀ When the E# digits are displayed, the LID LOCK LED will be turned OFF.
Up to five Fault/Error codes may be stored. Additional presses of Key 3 will
cause the system to display the next fault code. If there are no fault codes
saved, the LEDs will blink two times for each Key 3 press.

Exiting Service Diagnostic Mode
Use below method to exit diagnostic mode.
dz Pressing the Key 6/POWER button once.
Factory Mode
The Factory Mode includes: Factory Cycle and Factory Calibration Cycle.
1. Be sure the washer is in standby mode (plugged in with all LEDs off) and
lid is closed.
2. Follow the steps below within 8 seconds:
dz Press and release Key 1.
dz Press and release Key 2.
dz Press and release Key 1.
dz Press and release Key 2.
3. Entry into service mode is confirmed by all LEDs blinking 1 time and lid
locks.
4. Rotate the Encoder 1 step. LED status changes in LED groups 5 and 6.
5. Press Keys 1 to 6 one by one. Each Key press turns ON/OFF
corresponding group LED.
6. Successful completion of Encoder and Key, unlocks the lid.
7. Open and close the lid.
8. Factory cycle will be initiated by locking the lid.
Factory Calibration Cycle
This calibrates the main control to the washer for optimal load size estimation.
Calibration must be performed when any of the following components have
been replaced:
dz Main Control
dz Basket
dz Drive Assembly
dz Suspension, Motor
dz Capacitor and Shifter
Not performing calibration will result in poor wash performance.
Do NOT interrupt calibration, disturb washer, or remove power; otherwise
calibration must be repeated.
Basket must be empty to perform test (no water or clothes).
Calibration cycle runs for approximately 2 to 4 minutes*. Cycle completes when
lid unlocks and all LEDs are off.
Exit Procedure
Pressing the Key 6/POWER button anytime will exit Factory Mode.
