Troubleshooting
To avoid risk of electrical shock, personal injury or death; disconnect power to washer before servicing, unless
testing requires power.
Will Not Start
• Plug cord into live electrical outlet. Check for proper voltage.
• Check fuse or reset circuit breaker.
• Push any key to turn on the clothes washer and press the
Rotary Selector button to start the clothes washer.
• Close door and push the Rotary Selector
button to start the clothes washer.
• Check to see if the washer in a pause, soak or suds period in
the cycle. Wait briefly and it may start. (If washer is in suds
period, "Sd" will display instead of remaining time.)
• Check for restricted drain system.(If there is electrical problem
in drain system, "nd" Error will occur after 15 minutes.
• Check water supply.
• Check the line screen and water valve screen.
• Connection terminals for good connections.
• Check the machine control board terminal connections CN5,
CN6 for good connections.
(Refer to the component testing procedure.)
• Replace Main control board.
Leaking
• Make sure inlet hose connections are not leaking.
Check for rubber gasket damage due to over-tightening.
• Check standpipe for leak. Wrap a dry rag around the standpipe
opening. If rag becomes wet, leak is fault of home plumbing.
Be sure the standpipe is capable of accepting the flow of
water from the washer.
• Make sure end of drain hose is correctly inserted and secured
to drain standpipe.
• Check internal hose connections (fill, drain systems,
dispenser hoses & clamps).
• Check rubber boot. Remove, reposition and reinstall, if
necessary.
• Check for possible kinked dispenser to outer tub hose. Hot
water pressurization may force door open.
No Tumble
• Start normal cycle with an empty machine and allow a
fill to check tumble.
• Perform Board Output Test. or Quick Spin Test
(Before test, make sure that the tumbler is empty.)
• Check for loose connections at machine control board,
pressure switch, motor, tach harness and motor control.
(Refer to the component testing procedure)
• Check motor windings resistance. (CN9 pins
1 &3 = 11.6ohms(±7% 20°C/68°F basis), pins
1 & 2 = 11.6ohms(±7%20°C/68°F basis), Pin2
& 3 = 11.6 ohms (±7% 20°C/68°Fbasis)
• Check belt.
• Faulty Main Control Board.
• Faulty motor.
WARNING
Will Not Spin
• Check to make sure the door is fully closed.
• Check for water left inside the washer.
If present, see Will Not Drain.
• Perform Board Output Test or Quick Spin Test.
(Before test, make sure that the tumbler is empty.)
If it doesn't tumble after the test above, check unbalanced
load scenario, Main Control Board, and motor.
• Check for loose connections at Machine Control Board,
Pressure Switch, Motor, Tach Harness and Motor Control.
• Check belt.
No Water Fill
• Test water fill. Perform Board Output Test.
• Check to make sure water supply is turned on fully.
• Check electrical circuit and connections at the water valve,
and pressure switch.
• Check for kinks in inlet hoses.
• Check for clogged inlet screens.
• Visually check hot, cold, bleach and softener separately for fill.
• Check for low water pressure. May be dependent on
pressure entering home.
Variations may occur due to usage in the home at the time
machine is used.
• Check for frozen pipes and hoses.
• Check resistance of water valve coils. (Normal 1.18K ohms;
Check resistance of water valve coils. Check Pin #1 of CN5
and Pin # 1,2,3,4 of CN10.
• Check for loose connections at the pressure switch or on the
machine control board, CN3. (Refer to the component Testing
procedure)
