BASIC OPERATION OF COMMERCIAL STACKED

WASHER/DRYER

For additional information, see

www.WhirlpoolCommercialLaundry.com

IMPORTANT

Electrostatic Discharge (ESD)

Sensitive Electronics

ESD problems are present everywhere. ESD may damage

or weaken the electronic control assembly. The new control

assembly may appear to work well after repair is finished,

but failure may occur at a later date due to ESD stress.

Use an anti-static wrist strap. Connect wrist strap to green

ground connection point or unpainted metal in the appliance.

Touch your finger repeatedly to a green ground connection point

or unpainted metal in the appliance.

Before removing the part from its package, touch the anti-

static bag to a green ground connection point or unpainted

metal in the appliance.

Avoid touching electronic parts or terminal contacts; handle

electronic control assembly by edges only.

When repackaging failed electronic control assembly in anti-

static bag, observe above instructions.

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.

PART NO. W10920938A

-OR-

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:

11 minute wash period

3 rinses (extra rinse not enabled)

$2.00 wash price

Dryer is programmed at the factory as follows:

5 minutes per quarter

$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 =

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.
