Troubleshooting Electronic Control; Diagnostic Cycle - ALLIANCE AA9231 Service

Section 8 Service Procedures Unique to the Electronic Control Model Washers
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.
ADVANCE The ADVANCE option removes the
time from a cycle, starting at the
beginning of the cycle. The
ADVANCE pad moves you quickly
through a selected cycle in one or
five minute increments. By
watching the STATUS lights while
using ADVANCE, you can see to
which area in the cycle you have
advanced.
To use ADVANCE, select a cycle.
Press the ADVANCE pad. You will
notice the total cycle time will be
displayed when the ADVANCE pad
is pushed. Pressing the pad
momentarily will advance the cycle
one minute at a time. Holding the
pad down will advance the time in
five-minute increments.
If the washer is running and
ADVANCE is pressed, the washer
will stop and allow you to advance
through the cycle. The GO pad must
then be pressed to start or continue
the cycle.

The diagnostic cycle is used in conjunction with a
self-diagnostic routine chart located on the wiring
diagram sticker. Refer to Figure 56. To begin the
diagnostic cycle, follow the flow chart in Figure
56.
NOTE: If the symptom or problem corresponds to
one of the symptoms detailed on the following
