DIAGNOSTIC MODE

To enter the 'Diagnostic Mode,' first enter 'Start Operating Set-Up.'
Then press and hold the lower right (COLD) button for 1 second
while in set-up code six, anytime a diagnostic code is present, or while
dAS displays if operating with a Generation 2 card reader.
On entry to diagnostic mode, the entire display will flash, a cycle
in process is canceled, money in escrow is cleared, and diagnostic
codes are cleared. If a diagnostic code persists on the portion of
the washer/dryer not being tested, it can be acknowledged with the
lower middle (WARM) button prior to starting a diagnostic cycle.
This would be used when, for example, the dryer is out of service
and a diagnostic cycle is to be run on the washer.
There are six possible ways to initiate cycle activity from diagnostic
mode as follows:
1. Washer Cleanout Cycle – With the entire display flashing,
this cycle is started by pressing the center right (COLORS/
DELICATES) button.
Use the Washer Cleanout Cycle once a month to keep the inside
of your washer fresh and clean. This cycle uses a higher water
level. Use with liquid chlorine bleach to thoroughly clean the
inside of your washer. This cycle should not be interrupted.
IMPORTANT: Do not place garments or other items in the
washer during the Washer Cleanout Cycle. Use this cycle
with an empty wash drum.
2. Washer Cycle Credit – With the entire display flashing, a cycle
may be credited by pressing the lower left (HOT) button (CC will
display). When the service mode is exited, 'SELECT CYCLE' will
be displayed unless the end-of-cycle door opening is required.
3. Washer Manual Overview Test Cycle – With the entire display
flashing, this cycle is started by pressing the center left (COTTON/
WHITES) button. This cycle provides more typical full length fills,
tumbles, and drains, and allows for a more thorough analysis of
the washer operation, including pressure sensor behavior.
4. Washer Quick Spin Cycle – With the entire display flashing, this
cycle is started by pressing the center middle (PERM PRESS)
button. This cycle provides a method to quickly drain and spin
(remove water from the washer), if desired.
5. Washer Quick Overview Test Cycle – With the entire display
flashing, this cycle is started by pressing the lower middle
(WARM) button. This cycle provides a quick verification that
the cold and hot water valves, dispenser, and pump motor are
working. It also includes door lock, drain, and spin operations.
6. Dryer Field Diagnostic Cycle – With the entire display flashing,
this cycle is started by pressing the upper middle (PERM PRESS)
button. Additional time can be added by pressing the upper left
(COTTON/WHITES) button. This cycle can be used to credit lost
customer dryer time.
Pressing the lower right (COLD) button will exit diagnostic mode
and cancel a diagnostic cycle in process.
