TROUBLE SHOOTING
To avoid risk of electrical shock, personal injury or death; disconnect power to washer
before servicing, unless testing requires power.
TROUBLE DIAGNOSIS
No Water Fill
• Perform Quick Test Mode. Check all of Water Valves visually.
(Pre Wash Valve, 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#1 of CN2 and PIN#1,2,7,8,9 of CN3)
• 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.
Wet Clothes
• Unbalance due to not enough load. Put additional load.
• Due to excessive suds by using general detergent. Use HE (High-Efficiency) or reduce its quantity.
• Low Spin Speed or Drain Only was selected.
• Go to " Will Not Spin".
Will Not Lock
• Door is not aligned or closed properly.
• Perform Quick Test Mode. Check Door Lock.
Check the output voltage of Door Lock Coil.
If it reads 120V, change Door Lock Switch, and if not, change PCB. (Refer to PCB Connector Check.)
• Read Lock Switch and PCB (CN3). (Refer to PCB Connector Check.)
• Try Door Lock and check for 120V to Door Lock Connector. If 120V present, change Main Control Board and
if not, change Door Lock switch.
Will Not Unlock
• Check if the door is being pushed out, which may keep it from unlocking.
• Door locks itself when the water level is too high. Opening door will result in water draining from door
opening.
• Check the following with Board Input Test Mode.
Water Level (frequency): Over 23.80 KHz.
 If so, refer to "Will Not Drain".
Temperature (Inside Drum): Higher than 60ºC/140ºF.
 If so, wait until it drops.
When everything is normal, check PCB connectors and Door Lock Switch.
• Drain manually after removing the plastic drain hose holder.
• Display shows "LO". Turn off and on the unit. If "LO" keeps illuminating, check PCB and Door Lock Switch.
