GENERAL USER INFORMATION
Scrolling 'out of order' showing in display, followed by a
failure or diagnostic code
This condition indicates the washer is inoperative.
'0 Minutes' showing in display
This condition indicates the washer cannot be operated. Coins
dropped or debit inputs during this condition will be stored in escrow
but cannot be used until normal operation is restored by opening
and closing the door. If a door switch fails, it must be replaced before
normal operation can be restored.
Cold Start (initial first use)
Washer is programmed at the factory as follows:
11 minute wash period
I
3 rinses (extra rinse not enabled)
I
$1.75 wash price (PD models)
I
$0.00 wash price (PN models)

Warm Start (after power failure)
A few seconds after power is restored, if a cycle was in progress
at the time of the power failure, 'RESELECT CYCLE' will flash
in the display, indicating the need for a button press to restart
the washer.
PART NO. W10340707A
-OR-
Door Lock
The door will be locked when the cycle starts. The door will remain
locked until the end of a cycle or approximately 2 minutes after a
power interruption.
Pricing
After the door is opened following the completion of a cycle,
the display indicates the cycle price (unless set for free operation).
As coins are dropped or debit inputs arrive, the display will change
to lead the user through the initiation of a cycle.
Free Cycles
This is established by setting the cycle price to zero. When this
happens, 'SELECT CYCLE' will appear rather than a cycle price.
Display
After the washer has been installed and plugged in, the display will
show '0 MINUTES'. Once the washer has been plugged in and the
washer door opened and closed, the display will show the price. In
washers set for free cycles, the display will flash 'SELECT CYCLE'.
NOTE: Not displayed on washer as shown. Message scrolls
followed by the failure or diagnostic code.
