TECH SHEET - DO NOT DISCARD
IMPORTANT
Electrostatic Discharge (ESD)
Sensitive Electronics
ESD problems are present everywhere. ESD may
damage or weaken the electronic control assembly. The
new control assembly may appear to work well after repair
is finished, but failure may occur at a later date due to
ESD stress.
Use an anti-static wrist strap. Connect wrist strap to
green ground connection point or unpainted metal
in the appliance
Touch your finger repeatedly to a green ground
connection point or unpainted metal in the
appliance.
Before removing the part from its package, touch
the anti-static bag to a green ground connection
point or unpainted metal in the appliance.
Avoid touching electronic parts or terminal contacts;
handle electronic control assembly by edges only.
When repackaging failed electronic control
assembly in anti-static bag, observe above
instructions.
DIAGNOSTIC GUIDE
Before servicing, check the following:
Is the power cord firmly plugged into a live circuit
with proper voltage?
Has a household fuse blown or circuit breaker tripped?
Time delay fuse?
Are both hot and cold water faucets open and water
supply hoses unobstructed?
All tests/checks should be made with a VOM or DVM
having a sensitivity of 20,000 ohms per volt DC or greater.
Check all connections before replacing components.
Look for broken or loose wires, failed terminals, or wires
not pressed into connectors far enough.
The most common cause for control failure is corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary throughout test
procedures.
Connectors: Look at top of connector. Check for
broken or loose wires. Check for wires not pressed into
connector far enough to engage metal barbs.
FOR SERVICE TECHNICIAN'S USE ONLY
-OR-
Voltage checks must be made with all connectors
attached to the boards.
Resistance checks must be made with power cord
unplugged from outlet, and with wiring harness or
connectors disconnected.
DISPLAY FAULT/ERROR CODES
DISPLAY
EXPLANATION AND RECOMMENDED PROCEDURE
(PF) POWER FAILURE
"PF" flashes if the washer loses power during a running cy-
cle. The washer does not flash PF when it is first plugged in.
Press START to continue the cycle from the moment that
power was lost, - OR -
Press STOP/CANCEL to clear the display and
completely cancel the cycle.
(FL) OVERFILL CONDITION
"FL " flashes if an over fill condition occurs. This condition
occurs when excessive water in the tub causes the flood
switch to trip. The control must realize that the trip was due
to an over fill instead of a suds lock condition in order for FL
to be displayed.
With an over fill condition, the beeper repeats a warning
beep every 10 seconds with no timeout. The pump is cycled
in drain mode for a half minute on, half minute off until the
flood switch resets or power is discontinued to the unit.
Press STOP/CANCEL to clear the display.
(Er) PROCESSOR RESET ERROR
This error code is displayed if the control failed to save cycle
information during a power failure. This does not generate
an error code beep.
Press STOP/CANCEL to clear the display.
(LF) LONG FILL
If the water fill time exceeds 10 minutes, the water valves are
turned off and "LF" is flashed.
Press STOP/CANCEL to clear the display.
