Before servicing, check the following:
Make sure there is power at the wall outlet
n
and that the polarity is correct.
n Are both hot and cold water faucets open
and water supply hoses unobstructed?
n Check all connections before replacing
components. Look for broken or loose
wires, failed terminals, or wires not pressed
into or onto connections far enough.
n A potential cause of a control not functioning
is corrosion on connections. Observe
connections and check for continuity with an
ohmmeter.
Connectors: Look at top of connector.
n
Check for broken or loose wires. Check for
wires not pressed into connector far enough
to engage metal barbs.
n Resistance checks must be made with
power cord unplugged from outlet, and with
wiring harness or connectors disconnected.

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 six, 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 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. 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 Cycle – With the
entire display flashing, this cycle is started
by pressing the WHITES button. This
cycle provides more typical full length fills,
tumbles, and drains, 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 Cycle – 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, and pump motor are working. 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.
