TROUBLE SHOOTING
To avoid risk of electrical shock, personal injury or death; disconnect power to washer
before servicing, unless testing requires power.
TROUBLE DIAGNOSIS
• Read Lock Switch and PCB (CN6 & CN1). (Refer to PCB Connector Check.)
• 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.)
No Key Operation
• Option and Function buttons respond differently according to each cycle.
• Child Lock is being activated. To exit, hold down Soil Level Key and Signal Key simultaneously until it sends
out a beeping sound.
• When "End" illuminates on the display, only Power button works. Press Power button and make new cycle
selections.
Will Not Drain
• Check for any kink on the drain hose. If any, straight it out.
• Check for any restriction in the drain hose.
• Close the door and press the Start/Pause Button. For safety reasons, the washer does not tumble or spin with
the door open.
• When it is freezing outside, check if it is frozen inside the drain hose.
• Check if the water level signal input is correct. Go to Board Input Test Mode.
• Go to Quick Test Mode and do Drain Pump Test.
• Check if there is any twist in the hose (the one between Tub and Drain Pump).
• Check if it reads AC 120V at the pump when a spin cycle is selected.
• Read the winding resistance of the pump motor. (14.2±7% Ohms)
• Check the pump at CN1(PIN3) on PCB. It should read AC 110~120V. (Refer to PCB Connector Check)
Wrong Water Temperature
• Check if both of the water taps are fully open.
• Make sure the domestic water heater is set to deliver water lower than 120°F (49°C) hot water at the tap.
Also check water heater capacity and recovery rate.
• If the water heater is located far from the washer, screw out the hot water tap and let its water pass until you
get hot water.
• Too Hot/Too Cold: Reduced amount of water is supplied while PCB controls the influx to regulate the actual
temperature of the water in the tub. This may appear to be significantly hotter/colder than expected.
• Check if the temperature selection is correct.
• Disconnect inlet hoses from the Water Valve and remove any residue in the inlet screens.
Noisy and/or Vibration/Walking
• Check if the washer is leve LCD / LED and the lock nuts are tightened up on the bottom plate.
• Check if all of the shipping bolts and spacers are removed from the back panel.
• Check if load is big enough and there is no unbalance.If there is not enough load, put in a few towels to balance it.
• Check if the motor is fastened enough.
• Remove various trouble contributors (such as dust coat on the floor).
Rubber Feet Leaving Marks on Floor
• Use a pencil eraser to remove mark.
• Walk washer into location, do not drag.
Additive Cups Full of Water
• Small amount of water in bottom of additive cups is normal.
• Remove and wash Dispenser Tray, removable Cup, and Rinse Cap.
• Level washer.
Buttons do not Respond
• Option and Function buttons respond differently according to each cycle.
• Child Lock feature has been selected. To disable feature press and hold Temp and Spin simultaneously until a
beep is heard.
• When display shows "End", only the Power button will function. Press Power and make new cycle selections.
