GENERAL USER INFORMATION
Scrolling ‘out of order’ message, followed by a failure
or diagnostic code, showing in display
This condition indicates the washer/dryer is inoperative. Diagnostic
codes being displayed on the upper portion of the display pertain
to the dryer section, and diagnostic codes displayed on the lower
portion of the display apply to the washer section. Diagnostic codes
displayed on both the upper and lower portions of the display
pertain to the control system of both the washer and dryer.
Cold Start (initial use):
‘0 Minutes’ showing in display
This condition indicates the cycle is complete and the washer/dryer
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 has failed, causing ‘0 MINUTES’ to remain in the display
after the door is opened and closed, it must be replaced before
normal operation can be restored.
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 key press to restart
the washer or dryer.
Washer is programmed at the factory as follows:
n
11 minute wash period
n
3 rinses (extra rinse not enabled)
n
$2.00 wash price
Dryer is programmed at the factory as follows:
n
5 minutes per quarter
n
$1.50 dry price
Washer Door Lock
Prior to beginning a cycle, there is a door lock routine of lock/
unlock/relock, then cycle begins. 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 and then closed following the completion
of a cycle, the display indicates the cycle price (unless set for free
operation, where the display will flash ‘SELECT CYCLE’). As coins
are dropped or debit inputs arrive, the display will change to lead
the user through the initiation of a cycle.
There are four (4) types of dryer pricing:
Fixed ‘Vend’ Pricing
A dryer set up for ‘Fixed Cycle’ operation can only accept
additional time accumulated by increments equal to the length
of a complete dry cycle. A maximum of 99 minutes may be
purchased; no additional credit is given for coins dropped
with 99 minutes in the display.
Accumulator Pricing
If the price is set to one coin 1, then accumulator pricing is in effect.
Cycle time can be purchased one coin at a time up to the maximum
time of 99 minutes.
Fixed Cycle With Top Off Pricing
A dryer set to offer ‘Top Off’ capability will allow time to be added
to an existing dry cycle in increments equal to the number of
minutes of dry time per quarter (coin 1), up to 99 minutes, regardless
of the cost required to start the dryer. No credit is given for coins
or debit inputs entered when the control is displaying 99 minutes.
With Card Payment System: In Enhanced Debit Mode, the top off
price can be set independently (see VALUE OF COIN 2), and the top
off time is calculated according to the following equation:
top off time =
top off price
x full cycle length
full cycle price
Penny increment offset is not applied to top off purchases.
Free Cycles
This is established by setting the cycle price to zero. When this
happens, ‘SELECT CYCLE’ will appear rather than a cycle price.
Any cycle started as a free cycle will automatically terminate
when the door is opened.
