,¸ !ii! i,iiiiiiiiio :! ::! ii
To enter the "Washer Diagnostic Mode," first enter "Start
Operating Set-up." Then press and hold the QUICK CYCLE
button for 1 second while in set-up code 6, anytime a diagnostic
code is present, or while dAS displays if operating with Maytag
Data Acquisition set-up.
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,
it must be corrected before the following cycle options are
permitted.
There are five 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 BRIGHTS 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 the 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. Cycle Credit - With the entire display flashing, a cycle may
be credited by pressing the PERM. PRESS 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. Manual Overview Test - With the entire display flashing, this
cycle is started by pressing the WHITES button. This cycle
provides more typical full length fills, tumbles, drains, and
actuator dispenser movement, allowing for a more thorough
analysis of the washer operation, including pressure switch
behavior.
4. Quick Spin Cycle - With the entire display flashing, this
cycle is started by pressing the COLORS button. This cycle
provides a method to quickly drain and spin (remove water
from the washer) if desired.
5. Quick Overview Test - With the entire display flashing, this
cycle is started by pressing the DELICATES AND KNITS
button. This cycle provides a quick verification that the cold
and hot water valves, dispensers, and pump motor are
working, as well as actuator dispenser movement. It also
includes door lock, drain, and spin operations.
Pressing the QUICK CYCLE button will exit diagnostic mode
and cancel a diagnostic cycle in process.
