When the wash cycle is finished, the
Machine Status
window displays “U” to indicate that the
safety delay timer has expired and the door latch is unlocked. The decimal point on the right
side of the
Minutes Remaining
window flashes to indicate that the door has not been opened
since the wash cycle ended. Open the door and remove the goods.
When the attendant opens the machine door after a wash cycle ends, the display immediately
goes dark except for the
Machine Status
window. The
Machine Status
window flashes “C” to
prompt the attendant to close the door.

Viewing and Clearing the Accumulator
The controller maintains a wash cycle counter—called an
accumulator
—which increments when
a wash cycle is started. The procedure for viewing the accumulator is described in Section
3.3.3.1. The accumulator resets when power is removed from the machine, or it can be manually
reset by following the steps in Section 3.3.3.2.
The value stored in the accumulator increases by one count each time the
Start
button is pressed
to start a wash cycle.
3.3.3.1.
Viewing the Accumulator
—The accumulator contains a value from “000” to “999,”
representing the total number of all wash cycles performed since the last time the machine was
powered off or the accumulator was cleared. To view the contents of the accumulator, open the
door and turn the
Attendant
switch to the
Attendant
(horizontal) position.

As shown in Figure 12, the
Minutes Remaining
window displays the first two digits of the
accumulator value, while the
Machine Status
window displays the third digit. In the example
shown here, the machine has completed 37 wash cycles since the accumulator was reset. The
Select Wash Cycle

coin count
windows display normal operating values not included in the
accumulator count.
3.3.3.2.
Clearing the Accumulator
—Clear the accumulator by turning off power to the machine at
the wall disconnect, or by pressing the
Select
button four times while the accumulator is visible.
The accumulated value immediately resets to “000.”

Error Recovery
An error condition occurs if the machine controller detects a condition which might be unsafe or
cause machine damage. See Section 4.1. “Error Codes” for a detailed description of possible
errors and corrective actions.
Some errors, such as a might occur if the machine does not fill to level within the allotted 10
minutes, might be caused by transient conditions and require no immediate corrective actions
other than clearing the error. When an error of this type occurs, use the following procedure to
return the machine to service:
