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 the interface

without activating the appliance. The machine behavior appears similar to normal operation. With the door closed, pressing start, the appliance turns on and the display counts down by the second from the maximum time displayed with its respective cycle. The appliance turns off when it reaches “ ”.

The Automatic Loop will engage if no one interacts with the user interface for 3 minutes, or the start button hasn’t been pressed. The machine will simulate a cycle execution on the display only.

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 select (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 select (set) buttons for 3 secs. Continue to Step 4.

4 The message “ ” will blink 3 times in the center display. 5 If “ ” 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 “ ” ﬂashing 3 times in the center display. Unplugging the unit will not clear Demo Mode. See “Exiting Demo Mode” for more information.
