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.
(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.
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
• Perform Quick Test Mode. Check Door Lock.
Check the reistance for door lock. if Approx 0.2 ohm between the terminal of contact (white-Red wire),
and if not, change pcb(refer to pcb connector check).
• Read Lock Switch and PCB (CN3). (Refer to PCB Connector Check.)
Will Not Unlock
• Display shows "LO". Turn off and on the unit. If "LO" keeps illuminating, check PCB and Door Lock Switch.
• Read Lock Switch and PCB (CN3). (Refer to PCB Connector Check.)
• Perform Quick Test Mode. Check Door Lock. Check the resistance for door unlock if Approx 0.2 ohm between
the terminal of contact (white-blue wire), and if not, change pcb(refer to pcb connector check).
