TROUBLE SHOOTING WARNING 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). 15 [Technical information]WA484DSHA_03051B_EN.indd 15 2012-06-25 �� 11:12:02

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).
TROUBLE SHOOTING
To avoid risk of electrical shock, personal injury or death; disconnect power to washer
before servicing, unless testing requires power.
