TROUBLE SHOOTING
To avoid risk of electrical shock, personal injury or death; disconnect power to washer
before servicing, unless testing requires power.
TROUBLE DIAGNOSIS
Will Not Start
• Plug the unit into the wall outlet. Check for proper voltage.
• Check fuse or reset circuit breaker.
• Push any key to turn on the washer and press the Start/Pause key to run the washer.
• Close door and push the Start/Pause key to run the washer.
• Check if washer is in a pause, soak or suds process. Wait briefly and it may start. (If the washer is in suds
period, Suds will light up instead of remaining time.)
• Check for restricted drain system. (If there is electrical problem in drain system, "NO Draining" error will occur
after 15 minutes.)
• Check Water Supply.
• Check the line or water valve screen filter.
• Check if PCB connectors are assembled LCD / LED properly.
• Check if CN6 terminals on PCB are in good condition. (Refer to PCB Connector Check.)
• Replace PCB.
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 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.
CN8 pins 1 & 3 = 11.6ohms ±7%,
Pins 1 & 2 = 11.6ohms ±7%,
Pins 2 & 3 = 11.6 ohms ±7%
• Faulty Main Control Board.
• Faulty motor.
Will Not Spin
• Make sure to close the door completely.
• Check for water left inside the washer. If so, go to "Will Not Drain".
• Perform Quick Test Mode or Quick Spin Test. Does the washer spin? (Before the test, empty the unit inside.)
If it doesn't tumble after the above, change PCB. When the problem persists, change the motor.
• Perform Quick Test Mode or Quick Spin Test. Does the washer spin? If it does, Check Possible unbalanced
load scenario in normal mode.
• Check for loose connections at PCB, Water Level Sensor, Motor, Hall Sensor Wire Harness. (CN7,CN5,CN6)
(Refer to the Component Testing Procedure.)
• Check motor windings resistance. (CN8 Pin1&3 = 11.6 ohms (at ±7% 20°C/68°F),
Pin1&2 = 11.6ohms (at ±7% 20°C),
Pin2&3 = 11.6 ohms (at ±7% 20°C))
