Washer Diagnostic Modes - Maytag MHN33PD Instrucciones De Instalación

Washer Diagnostic Modes

To enter the "Washer Diagnostic Mode," first enter "Start
Operating Setup." Then press and hold the QUICK CYCLE key
pad for one second while in set-up code 6, anytime a diagnostic
code is present, or while dAS displays if operating with Maytag
Data Acquisition setup.
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 STOP/PAUSE key pad.
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 BRIGHTS key pad (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 key pad. This cycle
provides more typical full length fills, tumbles, drains, and
dispenser actuator 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 key pad. 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
key pad. This cycle provides a quick verification that the
cold and hot water valves, dispensers, and pump motor
are working, as well as dispenser actuator movement.
It also includes door lock, drain, and spin operations.
Pressing the QUICK CYCLE key pad will exit diagnostic mode
and cancel a diagnostic cycle in process.
DIAGNOSTIC CODES
If one of the following has occurred, the appropriate diagnostic
code will be in the display.
d5 Blocked coin 1 or coin drop control circuit failure (coin
recognition and price display disabled while blockage
persists).
PN Models Only: Set-up mode J. should be set
to _d to eliminate coin related diagnostic codes.
d9 Low voltage detected for eight seconds.
d13 Blocked coin 2 or coin drop control circuit failure (coin
recognition and price display disabled while blockage
persists).
F20 Slow Fill. The washer will not detect water input for four
minutes. Pressure switch failure or no water inlet. This
code is reported as d8 on d7.
F22 The door is not able to lock. Door lock error or someone
trying to start the washer, by pressing the door switch
with the finger. This code is reported as d17 on Accu Trac.
(For any other codes, check supplied Technical Sheet.)

SERVICE ACCESS CODE
This code can be entered to access service mode without
removing the console. It only functions on washers set up for 0
vend price without any Special Pricing setup, and the Coin/Debit
Option must be set to "J._d". If the washer is not in failure mode,
the door must be opened to proceed.
To enter the Service Access Code, press these key pads
in the following order: 1 – upper left, 2 – lower right, 3 – upper
right, 4 – lower left.
NOTE: If the Service Access Code procedure is not completed
properly, as noted above, there is a 15-second delay before it can
be attempted again.
There are three options to exit from the Service Mode:
1. Power down the washer; then reapply power.
2. Wait two minutes without touching any key pads (without
diagnostic modes running).
3. From Set-Up Code 8, press key pad #1 for four seconds.
WASHER HELP MODE
This mode is entered by pressing the BRIGHTS key pad while
in special pricing option mode 2.XX (or while dAS displays
if operating with Maytag Data Acquisition setup).
In help mode, other display symbols and elements are mapped
to reflect the state of various inputs and outputs as follows:
