Successful Entry
All LEDs turn off except the POWER button indicator and the
START button indicator begins to flash.
Load and Test Cycle Selection Procedure
Loads, the Service Diagnostic Verification Cycle, and the
Calibration Cycles are all assigned function numbers. These are
defined in the chart on the following page.
The seven segment display will indicate the current selected
function number.
Use the Soil Level and Temperature buttons or the cycle
selector knob (Maytag) to select a function number. The Soil
Level button or turning the cycle selector knob clockwise will
increment through the function numbers and the Temperature
button or turning the cycle selector knob counterclockwise will
decrement through the function numbers.
Commanding Functions 'On' and 'Off' in Service
Test Mode
With the desired function number on the seven segment
display, the function can be toggled on and off by pressing the
START button. Each press will toggle the state of the function
from 'off' to 'on' or from 'on' to 'off'. If the selected function
is currently active (commanded 'on'), the seven segment
display will flash the function number at a 1 Hz rate (1 flash
per second). If the load is currently commanded 'off', the
seven segment display will show the function number without
flashing. NOTE: Activating any of the spin or agitate functions
will result in functions 10–14 reporting their status as 'on'
because reported status is based on motor motion being
commanded.
Failure to Turn Load On Indication
If the number of functions (pumps, valves, and motor) allowed
on at the same time or the conditions to actuate the function
are not correct, the display will turn off momentarily and a
tone will sound. NOTE: There is a limit of four functions 'on' at
a time.
