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.

-OR-

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

‘----’ Inoperative State

These lines on the display indicate the appliance is inoperative.

Enter set-up mode to view diagnostic code.

‘0 Minutes’ showing in display

This condition indicates the appliance 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)

Appliance is programmed at the factory as follows:

■

14 minute wash period

■

3 rinses (extra rinse not enabled)

■

$1.75 wash price (PD models)

■

$0.00 wash price (PR 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 key press to restart

the washer.

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.

Debit Card Ready

This appliance is debit card ‘cable’ ready. It will accept a variety

of debit card systems, but does NOT come with a debit card reader.

Refer to the debit card reader manufacturer for proper washer

set-up. In models converted to a Generation 1 debit card system,

debit pulses represent the equivalent of one coin (coin 1).

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’.
