When performing live voltage measurements, you must do the following:
Verify the controls are in the off position so that the appliance does not start when energized.
Allow enough space to perform the voltage measurements without obstructions.
Keep other people a safe distance away from the appliance to prevent potential injury.
Always use the proper testing equipment.
After voltage measurements, always disconnect power before servicing.
ESD problems are present everywhere. Most people begin to feel an ESD discharge at
approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control
assembly. The new main control assembly may appear to work well after repair is finished,
but a malfunction 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 main control assembly in anti-static bag, observe above instructions.
This service data sheet is intended for use by persons having electrical, electronic, and
mechanical experience and knowledge at a level generally considered acceptable in the
appliance repair trade. Any attempt to repair a major appliance may result in personal injury
and property damage. The manufacturer or seller cannot be responsible, nor assume any
liability for injury or damage of any kind arising from the use of this data sheet.

DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown, or circuit
breaker or GFCI tripped? Was a regular fuse
used? Inform customer that a time-delay fuse
is required.
Is dryer vent properly installed and clear
of lint or obstructions?
Make sure both hot and cold water faucets
are open and water supply hoses are
unobstructed.
Make sure drain hose is not sealed into
drain pipe, and that there is an air gap for
ventilation. See Installation Instructions for
other drain hose installation considerations.
All tests/checks should be made with a
VOM (volt-ohm-milliammeter) or DVM
(digital-voltmeter) having a sensitivity of
20,000 Ω per volt DC or greater.
Resistance checks must be made
with washer/dryer unplugged or power
disconnected.
IMPORTANT: Avoid using large
diameter probes when checking harness
connectors as the probes may damage
the connectors upon insertion.
Check all harnesses and connections
before replacing components. Look for
connectors not fully seated, broken or
loose wires and terminals, pin insertion,
or wires not pressed into connectors
far enough to engage metal barbs.
A potential cause of a control not
functioning is corrosion or contamination on
connections. Use an ohmmeter to check for
continuity across suspected connections.

FAULT/ERROR CODES (WASHER) – The fault codes below may be indicated
under various conditions.
Display Explanation and Recommended Procedure
EAWater Level Sensor
This error code will appear if the pressure sensor is damaged (outside a
specific frequency range). The washer will beep and this error code will
appear when the water level reaches approximately 3/4" (18 mm) below
the overflow point for 3 seconds. It will then pause, drain the water to the
highest load size level, then turn off the pump. The lid will remain locked.
Check connections between UI and water level sensor. Test water level
sensor in Manual Load Test, page 10.
E1Low/No Water Fill
This error code will appear if the water level in the washer does not reach
the lowest level within 10 minutes or the set level within 20 minutes of
starting a cycle. Check water valve connections. Test water valves and
water level sensor in Manual Load Test, page 10.
E2Abnormal Drain
This error code will appear if the washer fails to reach the reset level after
draining the water for 8 minutes. Check installation of drain hose, check
drain hose for obstructions, and check connections between UI and drain
pump. Test drain pump in Manual Load Test, page 10.
E3Abnormal Spin
This error code will appear if the tub strikes the tub switch several times
without balancing itself. In a spin only cycle, the error code will appear the
first time the tub strikes the tub switch. See Spin Test, page 10.
ECAbnormal Circuit Motor Pulse Detection
The motor functions, but the circuit cannot detect the motor pulses.
The lid will remain locked for 5 minutes.
E4Lid Open
This error code will appear if the washer lid is opened or if the lid switch
is open at the start of the spin during a rinse and spin cycle. Close lid.
See Lid Switch Test, page 10.
ELLid Lock Malfunction
This error code will appear if the washer makes 10 unsuccessful attempts
to lock the lid or if the lid is detected as open during the wash or spin phase
where it must be closed and locked. Check for interference with lid or lid
lock mechanism. See Manual Load Test and Lid Switch Test, page 10.
E5Class B Software Error
Any class B software error will display E5.
EPEEPROM Abnormal
EEPROM is corrupted.
