4. INSTALLATION
Before servicing ask trouble the customer, what the trouble is. Check the adjustment (power supply is 120V~ remove the transit bolts....) Check the troubles referring to the troubleshooting. Decide service steps referring to disassembly instructions. Then, service and repair. After servicing, operate the appliance to see whether it works O K or NOT.
STANDARD INSTALLATION
The appliance should be installed as follows.
1 2
The appliance goes up by rotating the feet clockwise. The appliance come down by rotating the feet counterclockwise.
The drain hose should be placed under 100cm from the floor. CONNECT POWER PLUG
TEST OPERATION
Preparation for washing. Press the power button. Press the Start/Pause button.
START/PAUSE
POWER
Connect the power plug to the outlet. Connect the inlet hose.
Press the button TEMP. and the present temperature will be displayed.
Water removal
Power off and then power on. Check if the door can be opened after 3 minutes.
If SVC is needed during check, remove the remaining water by pulling out the hose cap.
5. OPERATION
Option
Extra Wash If the laundry is heavily soiled, Extra Wash course is effective. Extra Wash is available in Sanitary, Cotton and Perm. press. Extra Rinse This option can be used to add a rinse for people with sensitive skin. Selecting the Extra Rinse button is also recommended when washing heavily soiled fabrics which needs a lot of detergent, or when the wash load contains towelling fabrics that have a greater tendency to retain detergent.
Rinse hold
If you desire to leave fabrics in the machine without spinning after rinse to prevent them wrinkling, you may select rinse hold by pressing the spin button. If you want to drain and spin, when Rinse Hold function is proceed, Press the Start/Pause button to cancel the Rinse Hold function and select spin speed or program. Press the Start/Pause button again to start program. If you want to drain only, select the no spin. If lamp turns on, that function has been selected.

7. TROUBLESHOOTING
7-1.BEFORE PERFORMING SERVICE
Be careful of electric shock or disconnecting the parts while trouble shooting. Voltage of each terminal in 120V~ and DC while applying an electric current.
The digits means water level frequency (10-1 ex) 241 : Water level frequency = 241 =24.1 10-1

7-5.ERROR DISPLAY.
If you press the START/PAUSE button when an error is displayed. any error except will disappear and the machine will change into pause status. In case of if the error is not resolved within 20 sec., the in case of other errors, if the error is not resolved within 4 min., power will be turned off automatically and the error code will blink. But in the case of , power will not be turned off. ERROR 1
WATER INLET ERROR
SYMPTOM
CAUSE
Not reached to the water level (2 level) within 4 minutes after water supplied or not reached to the preset water level within 25 minutes.
