28 _ Troubleshooting

Problem

What To Do

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, “nd” error will occur after 30minutes.)

• Check Water Supply.
• Check the line or water valve screen filter.
• Check if PCB connectors are assembled properly.
• Check if CN2 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.

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. 

 

(CN9,CN1,CN8) (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))

No Water Fill

•  Perform Quick Test Mode. Check all of Water Valves visually. (Cold Water Valve, Bleach Water 

Valve, Softener dispenses using Cold & Bleach Water Valve, and Hot Water Valve.)

• Check if water taps are turned on fully.
• Check Water Valves and Water Level Sensor (Refer to PCB Connector Check)
• Check if there is any kink in inlet hoses.
• Check if inlet screens are clogged up.
• Check if water has enough pressure. If so, find out its contributors.
• Check if there is any frozen area in the unit (Drain Hose, etc)
•  Measure the resistance of Water Valve Coil.

 

(It should read 1.18K ohms. Check Pin#3 of CN6 and pin#1.2.3.4 of CN4)

• Check Pressure S/W and PCB for loose connections. (Refer to PCB Connector Check.) 

Tub Full of Suds

• Go to “Will Not Drain” and “Will Not Spin” and check the draining.
• Check PCB and Drain Pump for any loose wire connection.
• Perform Quick Test Mode or Board Output Test to drain.
• Use HE (High-Efficiency) or low sudsing detergent specially formulated for front load washers.
•  Reduce the amount of detergent for that specific load size and soil level. 

 

Keep in mind that towel creates more suds generally.

• Reduce the amount of detergent when water is soft, or laundry is small or lightly soiled.
• Do one more washing cycle with cold water and a table spoon of salt without detergent.
