Entering Diagnostic Mode:

1 Press power to turn machine on. 2 Rotate cycle selector ring (on some models) or repeatedly press cycle

button (on other models) to set cycle to normal. 3 Press the start button. 4 Power oﬀ machine by pressing the power button. 5 Power on machine by pressing the power button again. 6 Within 10 seconds, simultaneously hold temp + set buttons together for

3 seconds. 7 Diagnostic Mode is active when LED’s start blinking in sequence. This is

the pre-test position (00), which tests the lights and buttons.

Scrolling through Diagnostic Mode tests:

Tests are selected by using the same method used to select cycles. Models with the cycle selection button uses the cycles button to move forward, holding a little longer for the test 00 (cycle lights) to 01 transition and press the temp key to go back to the previous test. Models with the rotary cycle selector use the rotary selector ring to go forward and back.

Test numbers are brieﬂ y displayed when each test is selected. The test numbers also correspond to the selector LEDs numbered from 1 at the top going down.

Exiting Diagnostic Mode:

Hold the power key for 3 sec, when not in 00 test step Lights/Buttons, or unplug the unit.

Demo Mode/Washer Error Codes

Demo Mode:

The Demo works in two ways: interactive mode and automatic loop. The interactive mode enables the customer to use interface without activat-

ing the appliance. The machine behavior appears similar to operation. Start locks the door and the drum light turns on and the ETR is decreased each second. No water load/drain is executed.

If no one interacts with the interface for 3 minutes, or start button hasn’t been pushed, the machine an automatic loop instead, simulating the cycle execution only on display. This automatic loop cycles until someone touches the user interface and it goes back to interactive mode.

Entering Demo Mode:

1 Press power and look for console light up. 2 For Rotary Dial Cycle Select Washer: Within 10 seconds select fast

wash and then simultaneously press and hold temp and set buttons for 3 secs. Skip to Step 4.

3 For Push Button Cycle Select Washer: Within 10 seconds select rinse &

spin and then simultaneously press and hold temp and set buttons for 3 secs. Continue to Step 4.

4 The message “dn” will blink 3 times in the center display. 5 If “dn” message does not appear, turn oﬀ machine and repeat previous

steps.

NOTE

Once Demo Mode is activated, every time the machine is turned on, Demo Mode is automatically recalled; this occurrence is signaled at the start-up

by the text “dn” ﬂ ashing 3 times in the center display. Unplugging the unit will not clear Demo Mode. See “Exiting Demo Mode” for more information.

Exiting Demo Mode:

To exit Demo Mode, perform the same sequence that was described earlier to enter Demo Mode. If successful, the machine will beep, then the display will cycle oﬀ and on, followed by another beep. You may also perform a Factory Default Reset - see below.

Factory Default Reset:

1 Press power and look for console light up. 2 Wait at least 10 seconds, then simultaneously press and hold soil and

options buttons for 3 secs.

To return to factory settings, press the soil and options buttons at the same time and hold until the signal sounds.

Recalling Last Error Code:

1 Press power and look for console light up. 2 Wait at least 10 seconds, then simultaneously press and hold temp and

set buttons for 3 secs. 3 The display will show the last error in memory. 4 Clear the display and return to normal operation by touching any but-

ton or by pressing the power button.
