IMPORTANT 
Electric 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 ground connection 
point or unpainted metal in the appliance.
  –OR–
  Touch your finger repeatedly to 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 contact; handle electronic 
control assembly by edges only.
•  When repackaging failed electronic control assembly in anti-static bag, 
observe above-mentioned precautions.
IMPORTANT 
Electrical Shock Notes
•  The power must be disconnected before servicing by unplugging 
the machine or disconnecting the circuit breaker.
• 
The machine must be electrically grounded through the lead 
in the 3-prong power cord. The cord must be plugged into a 
grounded appliance outlet that has been properly installed. 
If local codes require an additional ground connection, use a 
16-gauge or larger wire to connect the washer cabinet to an 
established ground. In all cases, the grounding method must 
comply with all local electrical codes and ordinances.
DIAGNOSTIC GUIDE
Before testing washer operation, check the following:
•  Is the power cord firmly plugged into a live circuit?
•  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? Before opening the unit make sure the washer is unplugged 
from power outlet.
•  Check all connections before replacing components. Look for broken or loose 
wires, failed terminals, or wires not pressed into connections 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.
•  Resistance check must be made with power cord unplugged from outlet, 
and with wiring harness or connectors disconnected.
