lights flashing on SMART AUTO & HEAVY ?

Here are some troubleshooting information and diagnostics below.

Temp Sen-sor error
When 0.2V or below, or 4.5V or above is maintained for over 3 seconds
Thermistor terminal is not connected
Possible defect: Thermistor Main PBA
Heater error
When the temperature change is 4℃ or less within the first 10 minutes after the heating starts
Heater terminal is not connected
Possible defect : Main Wire-Harness, Heater, Main PBA
High temp
Heating error.
When the temperature of the Thermis-tor is 80℃ or above for more than 3 seconds during operation.
Water temperature is 80℃ or above
Possible defect : Thermistor , Main PBA
Low-level water error
1.When low level sensor is detected
over 5 seconds during wash opera-
tion, this error occurs.
2.When high level sensor is not
detected after water supply was done,
drain & refill the water. After then, if
high level sensor is not detected
again, this error occurred.
Water Level Sensor terminal is not connected
Possible defect : Assy case sensor, Water Level Sensor , Main PBA
Water supply error
1. When the pulse of 100 or less is de-tected even 73 seconds after the water supply
2. When flow meter pulse is 5 or less for 13 seconds after the water supply starts
3. When the water supply is not fin-ished until 6 minutes after the water supply starts
Alien particles within water supply valve
Water supply valve terminal not con-nected
Possible defect : Main PBA, Water supply valve , Flow Meter
High temp
Water sup-ply error
When 80℃ or above is detected during water supply
Water supply temperature is 80℃ or above
Possible defect: Thermistor, Main PBA
Drain error
When OFF status of Low Level S/W is not detected within 3 minutes during the drain.
Alien particles clogging in drain hose
Drain pump terminal is not connected
Possible defect : Drain pump, Water Level Sensor , Main PBA
Over-level water error
When overflow detection AD data is 3.5V or below for 3 seconds. (When leakage sensor detects 3.5V or below for 1 second during water supply)
Alien particles within water supply valve
Case Sensor part breakdown
Possible defect : Flow Meter, Main PBA, Water supply valve
Leakage error
When leakage sensor detects 3.5V or below for 1 second
Possible defect : Each hose connec-tion , Sump and Tub assembly, Drain Pump assembly , Main PBA
Button error
When the button is pressed continu-ously for over 10 seconds
Possible defect : Sub PBA in control panel, Main PBA
Door open warning
When door is open in washing period.
Door is not close properly in test mode only.
Possible defect : Door lock switchSmart Auto‘ LED
•Drain pump •Inlet Valve •Flow Meter •Water Level Sen-sor •Turbidity
Door open warning
Water supply Error
Low level wa-ter Error
Turbidity Error
If Door is open, Door open warning (‗Delicate + Smart Auto‘ LED) will blink. If low level sensor is not detected, Drain is executed. Water sup-ply will be executed when low level sensor is detected. If water is not fully supplied (sensing on flow-meter), the Water Supply Error (‗Smart Auto‘ LED) will blink. When high level sensor is not detected after water supply was done, Low-level water error (‗Normal + Heavy + Smart auto‘ LED) will blink. When Turbidity problem is occurred after water supply was done, Turbidity Error (‗Normal + Heavy‘ LED) will blink. If all func-tions in this mode are completed, Wash LED will blink.
No.2
‗Delicate‘ LED
•Circulation Motor
A nozzle does not inject wa-ter.
If Low Level sensor is detected before Circulation Motor is operating, (‗Delicate + Sanitize‘ LED) will blink. When water is filled enough, Circu-lation Motor -2(190W) will be operated.
No.3
‗Delicate‘ + ‗Smart Auto‘ LED
•Circulation Motor
A nozzle does not inject wa-ter.
If Low Level sensor is detected before Circulation Motor is operating, (‗Delicate + Smart auto + Sanitize‘ LED) will blink. When water is filled enough, Circulation Motor- 1(150W) will be operated.
No.4
‗Heavy‘ LED
•Circulation Mtor •Heater •Thermistor •Dispenser
Heater Error
If Low Level sensor is detected before Circulation Motor is on, (‗Heavy + Sanitize‘ LED) will blink. When water is filled enough, Circulation Motor 1(150W) and Heater will be operated. When the temperature meet 60℃ or above, the heater is turned off. If Heater or Thermistor have prob-lems, the Heater Error (‗Heavy + Delicate‘ LED) will blink.
Dispenser will operate during 130 seconds only one time.
No.5
‗Heavy‘ + ‗Delicate‘ + ‗Smart Auto‘ LED
•Dry Fan Motor • Dispenser
The Dry Fan motor does not work.
Operate the Dry Fan Motor and check whether Rinse aid is filled or not.
If there is not rinse aid in Dispenser, Rinse Refill lamp is ON.
No.6
‗Normal‘ LED
Valve Overflow
Over level water Error
Water is supplied until Over-level water error (‗Heavy + Smart Auto‘ LED) is blinked. If Over-level water error occurs, overflow sensor OK.
No.7
‗Normal+ Smart Auto‘ LED
Drain Pump Wa-ter Level Sensor
Drain Error
Drain pump will drain until low level sensor is detected.
If Low level sensor is not detected after 60 seconds, Drain Error (‗Delicate‘ LED) will blink.
No.8
‗Normal‘ + ‗Delicate‘ + ‗Smart Auto‘ LED
•Inlet Valve •Circulation Mo-tor •Dry Fan Mo-tor •Drain Pump •Heater
Operates each part when the key is pressed. (See the below)
When the ‘Smart Auto’ Key is pressed Water supply is On (‘Smart Auto’ LED On) and pressed again it is Off (‘Smart Auto’ LED Off)
When ‘Heavy’ Key is pressed each time, it works the Circulation Motor-1 is On (‘Heavy’ LED On) -> Off (‘Heavy’ LED Off) -> Circulation Mo-tor-2 is On (‘Heavy’ LED On) -> Off (‘Heavy’ LED Off) -> Dry Fan Mo-tor is On (‘Heavy’ LED On) -> Off (‘Heavy’ LED Off), Drain Pump is On (‘Heavy’ LED On) -> Off (‘Heavy’ LED Off). When ‘Delicate’ Key is pressed, Heater is On (‘Delicate’ LED On
