7. TROUBLESHOOTING 7-1. BEFORE PERFORMING SERVICE Be careful of electric shock when disconnecting parts for while troubleshooting. The voltage of each terminal is 120V AC and DC when the unit is plugged in. 7-2. QC TEST MODE. The washer must be empty and the controls must be in the off state. ¤Á Press the SPIN SPEED and SOIL LEVEL buttons simultaneously. ¤Ł Press the Power button, while the above condition. Then buzzer sound twice.
7-4. ERROR DISPLAY If you press the START/PAUSE button when an error is displayed, any error except will disappear and the machine will go into the pause status. In case of if the error is not resolved within 20 sec., or 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 8 9 OVER CURRENT ERROR LOCKED MOTOR ERROR SYMPTOM CAUSE • MAIN PWB ASSEMBLY is out of order. • Winding in the STATOR ASSEMBLY is short-circuited. • The connector (3-pin, male, white) in the MOTOR HARNESS is not connected to the connector (3-pin, female, white) of STATOR ASSEMBLY. • The electric contact between the connectors (3-pin, male, white) in the MOTOR HARNESS and 4-pin, female, white connector in the MAIN PWB ASSEMBLY is bad or unstable.
8. ERROR DIAGNOSIS AND CHECK LIST 8-1.DIAGNOSIS AND SOLUTION FOR ABNORMAL OPERATION SYMPTOM No power GUIDE FOR SERVICE CALL Is the power plug connected firmly to 120V AC outlet? YES Power failure? or Breaker opened? Is the outlet controlled by a switch? NO Visit to service. Water inlet trouble Is displayed? YES Is the tap opened? YES Is the tap frozen?
