DISPLAY FAULT/ERROR CODES
“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” 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.
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.
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.

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
-OR-
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.
DISPLAY
EXPLANATION AND RECOMMENDED PROCEDURE
■
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.

Summary

Important Safety and Handling

Electrostatic Discharge (ESD) Protection

ESD can damage electronic control assemblies. Use anti-static measures.

Diagnostic Guide

Pre-Service Checks

Essential checks before servicing include power, fuses, water supply, and using a VOM/DVM.

Common Failure Cause

Corrosion on connectors is the most common cause for control failure.

Display Fault and Error Codes

PF (PF) Power Failure

Indicates washer lost power during a cycle. Press START or STOP/CANCEL to clear.

FL (FL) Overfill Condition

Excessive water tripped flood switch. Press STOP/CANCEL to clear.

Er (Er) Processor Reset Error

Control failed to save cycle info during power failure. Press STOP/CANCEL to clear.

LF (LF) Long Fill

Water fill time exceeds 10 minutes. Valves turn off. Press STOP/CANCEL to clear.

Display Fault and Error Codes (Continued)

CE (CE) Communications Error

Breakdown in communication between controllers. Unit beeps once. Check serial communication.

Ld (Ld) Long Drain

Takes over 5 minutes to pump out water. Press STOP/CANCEL to clear.

CA/CI Current Limit

Motor controller senses current limit trip. Returns to standby. Press STOP/CANCEL.

ob Off Balance

Unrecoverable off-balance condition. Lid switch must be opened to redistribute load.

Diagnostic Tests Overview

Diagnostic Tests Activation

Tests activated by 'Key Dance' sequence within 5 seconds. STOP/CANCEL stops tests.

Water Inlet and Dispenser Valve Test

Tests water valves using specific touchpad sequences and observing control actions.

Specific Diagnostic Tests

Nutate and Recirculate Test

Tests drive motor nutation, recirculation, and fill valves. Self-terminates after 3 minutes.

Spin and Drain Test

Tests spin and drain functions. Activates 60-rpm spin and drain for 40 seconds.

Automatic Service Diagnostics

Test Procedure

Checks drive motor (nutate/spin), fill valves, and pump motor. Self-terminates after 2 minutes.

Motor and Component Resistance

Provides resistance values for drive motor, pump motor, and electronic components.

Console Switches and Indicators Test

Test Procedure and Functionality

Tests keypad and LED functionality. Pressing touchpads should produce a beep.
